With surface temperatures Rho Cassiopeiae is a yellow hypergiant star, the brightest one in the night sky. be close to exploding as supernovae. It is classified as a variable star The location of Rho Cassiopeiae in the night sky. Gamma Cassiopeiae is a Be star, a variable star, and a binary. of Elements Heavier Cassiopeia. Rho Cassiopeiae, one of the brightest yellow hypergiants, is the best candidate to undergo a supernova explosion in the near future, according to astronomers using the Utrecht Echelle Spectrograph on the William Herschel Telescope.This star is 550,000 times brighter than our Sun, and although it is over 8,000 light-years distant, it can be seen without optical aids. This book presents the status of research on very massive stars in the Universe. (7,000 �K) to 5,000 �F (3,000 �K). These include Rho Cassiopeiae, Eta Carinae, RS Ophiuchi, U Scorpii, VY Canis Majoris, Betelgeuse, Antares, and Spica. molecules such as Titanium The star, 450 times bigger than our Sun, is a likely candidate to go supernova within the next 50,000 years. CfA Despite being located some 10,000 light-years (ly) away, the star is visible to the naked eye because it is over 500,000 times . V509 Cassiopeiae. Im sure that the next naked-eye Type II supernova will come from a progenitor star that already has a photographic record somewhere. Two of the most luminous stars in the entire galaxy lie in this region. The star is one of the brightest stars in the Milky Way and is thought to be a type of variable star. Its outer layer stars that are at a very evolved stage of their life and may Caph lies at a distance of 54.7 light years from Earth. But it will retain more than enough to detonate as a supernova in the next several hundred thousand years. The star is likely ejecting mass at a rapid rate.

With an absolute magnitude of -9.5, some 500,000 times as bright as our Sun, it still appears visible without optical aid. With a spectral type of F8-G2 Ia0 (Teff= 6500-7200 K), and a luminosity of log (L*/Lsun)~5.7 (R*~ 400-500 Rsun), Rho Cas is one of a small sample of Galactic YHGs.

It is about 3,400 light-years from Earth, yet can still be seen by the naked eye as it is over 300,000 times brighter than the Sun. and images. CfA Discover world-changing science. The supernova, however, may have been recorded by the English astronomer John Flamsteed, who noted a sixth magnitude star on August 16, 1680 and recorded it as 3 Cassiopeiae. Found insideSeveral large stars within the Milky Way have been suggested as possible supernovae within the next million years. These include Rho Cassiopeiae, Eta Carinae, RS Ophiuchi, UScorpii, VY Canis Majoris, Betelgeuse, Antares, and Spica. Credit : Stellarium Rho Cass is one of the few naked eye examples of a yellow hypergiant star, and varies from magnitude +4.1 to +6.2 over an . Dr. Garik Israelian, one of the members of the discovery team, said: "Rho Cassiopeiae could end up in a supernova explosion at any time as it has almost consumed the nuclear fuel at its core. It is also a particularly rare type of star as it is a yellow hypergiant, and only six other such stars have been observed in our galaxy. In 2003, an international team of astronomers named ρ Cas as the best candidate for an imminent supernova explosion.
