Cluster), NGC 7789 (the White Rose Cluster), NGC 663, and NGC 654, and the irregular starburst galaxy IC 10, one of our neighbours in the Local Group. Achernar was only recognized as a Be star in 1976. Gamma Cassiopeiae does not have a formal name. From Redmond , Gamma Cassiopeiae Nebula is visible all night because it is circumpolar. 4.00 – 4.26), and Kappa Canis Majoris (mag. The name Navi (Ivan spelled backwards) was given to it by the American astronaut Virgil Ivan “Gus” Grissom, commander of the Apollo 1 mission, which ended with the deaths of all three crew members during a pre-launch test on January 27, 1967. It is the prototype of the class of Gamma Cassiopeiae variable stars. Looking through our home galaxy - the Mikly Way with its countless wonders as well as at other galaxies closer or more distant from the Milky Way, all of that make us to believe that one day we could better understand the universe and our role in it. Gamma Cassiopeia Region The bright star near the center, Navi, is part of the constellation Cassiopeia, and it ionizes the nearby gases in the emissions and reflections nebula cataloged as IC 63 and IC 59. Stars classified as Gamma Cassiopeiae variables include Gomeisa in Canis Minor (mag. 495. Gamma Cassiopeiae, also known as Navi, is the prototype Gamma Cassiopeiae variable star, a type of star that has a variable disc of material flung off by the high rotation rate of the star. Like other exceptionally massive stars, it has evolved very quickly and will not live a very long life. It will continue to be observable until around 04:20, when it sinks below 22° above your north-western horizon. Thanks to astrophotography you can see things not not available to an open eye, a colorfull wonders of the Universe. Please take a deep breath and dive in together with me if you have not done it already.

Vermutlich handelt es sich um ein enges Doppelsternsystem, bestehend aus einem Riesenstern und einem Neutronenstern. Schedar and other bright stars of Cassiopeia lie in a rich field of the Milky Way and can be used to find a number of bright deep sky objects. Since there were no signs of a companion in the spectrum of Gamma Cassiopeiae, the system was adopted as a single-lined spectroscopic binary, that is to say, a system where the spectrum of only one component is seen and the presence of a companion is inferred from spectral lines periodically shifting towards the blue, then towards red and then towards blue again, indicating that the components are moving toward us and away from us, i.e. IC 59 lies a bit farther from the star and shows less hydrogen-alpha emission and more reflected blue light. These lines are caused by a circumstellar disk of material lost from the star. Navi occasionally outshines the brightest star in Cassiopeia – Alpha Cassiopeiae, reaching a magnitude of 1.6, due to its variability in brightness. Gamma Cas is the middle star of Cassiopeia, a 2nd magnitude star that is the prototype for a class of eruptive variable stars. The star is running out of the supply of hydrogen in its core and is on its way to evolving into a giant. Guiding … Im Ausbruch kann sich der Spektraltyp bis zu F5 abkühlen. The study suggested that the companion had a mass between 0.7 and 1.9 solar masses and was not responsible for the X-ray emission detected from the star.

Pictures, altitude charts, data sheet and sky map for Gamma Cassiopeiae Nebula - - Bright nebula in Cassiopeia Constellation The star pattern appears as a W during the northern hemisphere spring and summer. Typically, they are fast spinning class B subgiants, giants or sometimes main sequence stars, that show brightness variations with larger amplitudes than other Be stars. A study of the star’s X-ray flux found variations with a period interpreted as the star’s rotational period (1.21 days), indicating that the X-rays did not come from a companion. High overhead in northern autumn evenings lies the W- shaped constellation Cassiopeia, in mythology the Queen and mother to Andromeda, to us brilliant against the background of the Milky Way and fully circumpolar from most of the United States and all of Canada. 4.8 – 5.5), Lambda Pavonis in Pavo (mag. Cassiopeia is one of the 88 modern constellationswe see today. Gamma Cassiopeiae also has two visual companions, catalogued as components B and C. The first companion is a magnitude 11 star separated by about 2 arcseconds from the primary, and the second is a magnitude 13 star almost an arcsecond away from the primary. Also known as the ghost of Cassiopeia, IC 63 is being shaped by radiation from a nearby unpredictably variable star, Gamma Cassiopeiae, which is slowly eroding away the ghostly cloud of dust and gas. IC 59 und IC 63 sind gemischte Emissions-Reflexionsnebel die vom hellen Stern Gamma Cassiopeiae zum Leuchten gebracht werden. 2.24) and Caph (mag.

At its brightest, the star outshines both Schedar (mag. It allows us to look into the history and take a picture of it. High overhead in northern autumn evenings lies the W- shaped constellation Cassiopeia, in mythology the Queen and mother to Andromeda, to us brilliant against the background of the Milky Way and fully circumpolar from most of the United States and all of Canada. It varies from a maximum of 1.6 magnitude during an eruption to 3.0 magnitude when the mass it is expelling from its equator blocks some of its light. It has an apparent magnitude of 7.0 and lies at a distance of 2,143 light years. It is one of the 48 Greek constellations, first listed by the Greek astronomer Claudius Ptolemy in the 2nd century CE. Complex nebula to capture (only mag. It exhibits irregular variations in brightness, which ranges between 2.20 magnitudes and 3.40 magnitudes. IC59 & IC63: The Gamma Cassiopeiae Nebulae Gamma Cassiopeiae, the middle star of the famous W-shaped constellation, is a hot giant with a surface temperature of 25,000°C (compared to 5,500°C for our Sun) and a mass fifteen times our Sun's. Gamma Cassiopeiae is 70,000 times more luminous than the Sun and is surrounded by two faint reflection / emission nebulae, IC 59 and IC 63. Many Be stars are variable in brightness. The entire constellation is visible from locations between the latitudes 90° N and 20° S. The 10 brightest stars in Cassiopeia are Gamma Cassiopeiae (mag. This asterism is formed by five bright stars; Epsilon, Ruchbah (Delta), Gamma, Schedar (Alpha Cassiopeiae) and Caph (Beta Cassiopeiae). Notable deep sky objects in the constellation include the neighbouring Heart and Soul nebulae (IC 1805 and IC 1848), two large emission nebulae 7,500 light years away, the emission nebulae NGC 281 (the Pacman Nebula) and NGC 7635 (the Bubble Nebula), the open clusters Messier 52, Messier 103, NGC 457 (the E.T. Gamma Cassiopeiae is classified as a Be star, a non-supergiant blue class B star showing Balmer (hydrogen) emission lines in its spectrum. 10), also with this dominant variable star close who makes so difficult obtain all details and nuances. The decretion disk causes both brightness variations and hydrogen emission lines in the star’s spectrum. With a temperature of 25,000 K, a mass 17 times that of the Sun, luminosity 34,000 times solar, and an age of 8 million years, Gamma Cassiopeiae is the youngest, most luminous, hottest and most massive of the five stars that form the W. At a distance of 550 light years, it is also by far the most distant. 4.92 – 5.39) in Canis Major. The companion is believed to be more evolved than the primary and to have transferred some of its mass to the brighter star during an earlier evolution phase. Its high mass seals its fate as a supernova in the not-too-distant astronomical future. It will then reach its highest point in the sky at 20:44, 65° above your northern horizon. Reply . Posted by. Der Stern ist eine starke Röntgenquelle am Himmel. Emission and reflection nebulas located in Cassiopeia. Like its neighbour Caph, Gamma Cassiopeiae is an example of gravity darkening. Gamma Cassiopeiae is informally known as Navi or Tsih. Maybe the ISO is too high. Gamma Cassiopeiae was identified as an X-ray source in 1976, but it was unclear whether the star itself was the source or it had a mass-accreting binary companion. Gamma Cassiopeiae is located in the northern constellation Cassiopeia. Circumpolar in the northern hemisphere, Cassiopeia has been known to observers since ancient times. With a declination of +60° 43’, the star is visible from all locations north of the equator, but cannot be seen south of the latitude 29° S. Observers in southern latitudes where the star rises can only see it appear low above the horizon at certain times of year. GAMMA CAS (Gamma Cassiopeiae). IC 59 appears north of the star, while IC 63 is more to the northeast. 3.37), Achird (Eta Cas, mag. Gamma Cassiopeiae is an eruptive variable star. The best time of year to see the stars and deep sky objects of Cassiopeia is during the month of November, when the constellation is prominent in the evening sky. Gamma Cassiopeiae underwent two such events in 1935-36 and 1939-40, brightening to above magnitude +2.0, then rapidly dimming to magnitude +3.4. Segin, the other hot class B star in the asterism, has 9.2 solar masses, a temperature of 15,174 K, a luminosity 2,500 times that of the Sun and it is about 140 light years closer to us. Despite their almost identical proximity to Gamma Cassiopeia and similar appearance, Sh2-185, or IC 59 (lower) and IC 63 (above and right) are actually quite different in … 3.95), Kappa Cassiopeiae (mag. The star rotates very rapidly and bulges outward along the equator. The other three stars are much cooler, less luminous, less massive, considerably older, and much closer to us. Gamma Cassiopeiae is a star at the center of the distinctive "W" asterism in the northern circumpolar constellation of Cassiopeia. Informally known as Navi, it is one of the four brightest stars in Cassiopeia. A more advanced amateur astrophotography could require some more sophisticated and expensive equatorial mounts and potentially cooled CCD cameras. 3.44), Fulu (Zeta Cas, mag. The emission-reflection nebulae IC 59 and IC 63 lie only 3-4 light years from the star. share. As another effect of the star’s fast rotation, a lot of material from the surface is ejected and forms a hot disk of gas. Originally, the name was applied to Kappa Cassiopeiae and Gamma Cassiopeiae represented one of the horses pulling the chariot of Wang Liang, but this was later changed and Gamma came to represent the whip. In the late 1930s it underwent what is described as a shell episode and the brightness increased to above magnitude +2.0, then dropped rapidly to +3.4. Other bright stars that are examples of this include Achernar, Alderamin, Altair, Rasalhague, Regulus, and Vega. Nicknamed the Ghost of Cassiopeia or the Ghost Nebula, IC 63 is slowly being eroded away by the star’s radiation. The star’s estimated age is only 8 million years. In winter, it appears inverted. It lies near several other constellations associated with the myth of Perseus: Perseus, Andromeda, Cepheus and Pegasus. Gamma Cassiopeiae has the stellar classification B0.5 IVe, indicating a subgiant star appearing blue or blue-white in colour. With an apparent magnitude that varies from 1.6 to 3.0, it sometimes outshines its neighbours Schedar, Caph and Segin to become the constellation’s brightest star. However the final results would also depend on the quality of skies you use and which should be affected by light polution as little as possible and your processing skils. The star is a known X-ray source. Amateur astronomy can be a rewarding and fascinating hobby. It will become visible around 17:55 (EST) as the dusk sky fades, 54° above your north-eastern horizon. It is one of the five stars that form Cassiopeia’s recognizable W asterism. Please join me with my adventure through a starry night sky. Guiding telescopes or lenses:Celestron OAG Deluxe, Teleskop Service TSOAG9 Off-Axis Guider. Imaging cameras:ZWO ASI183MM-Cool, ZWO ASI1600MM-Cool. Seen from locations south of the equator (where the asterism is visible), it always appears inverted. 2.68), Segin (Epsilon Cas, mag. The star was reported to be a binary with a period of 203.59 days in a study published in 2000. I really like this ‘subject’ … and you did a great job on it. No está en la foto pero aun así es posible sentir la fuerte presencia de esta estrella tan béstia (en la parte superior derecha de la imagen) como esa luz azul que va a la nebulosa. Gamma Cassiopeiae itself usually shines at magnitude 2.25, but it has been observed to fade to magnitude 3.0 and brighten to magnitude 1.6. With an apparent magnitude of 10, they are quite faint. Gamma Cassiopeiae Nebula (IC63) DSOs. At dusk, it will become visible around 19:33 (PDT), 47° above your north-eastern horizon. The X-ray radiation emanating from the star is about 10 times stronger than the radiation detected from other Be or B stars. that they are orbiting around a common centre of mass. Stretching across an area of 598 square degrees, it is the 25th constellation in size.
