John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Supernovae are important astronomical objects. They tell us about how stars die and are used as measuring sticks to investigate distant galaxies. But there is still some uncertainty as to how the supernova process proceeds in some cases. It is believed that the most common progenitor of Type II supernova is the collapse of supergiant stars. In this phase of their evolution stars oscillate between red supergiant and more...

redOrbit Staff & Wire Reports - Your Universe Online A team of Japanese researchers has discovered evidence that a yellow supergiant (YSG) was, in fact, the progenitor for a recently discovered supernova -- a discovery which they say raises serious questions regarding our understanding of the evolution of massive stars. Melina Bersten of the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) and colleagues analyzed evidence and discovered that supernova...

Astronomers have spied a faraway star system that is so unusual, it was one of a kind -- until its discovery helped them pinpoint a second one that was much closer to home.In a paper published in a recent issue of the Astrophysical Journal Letters, Ohio State University astronomers and their colleagues suggest that these star systems are the progenitors of a rare type of supernova.They discovered the first star system 13 million light years away, tucked inside Holmberg IX, a small galaxy that...

Supergiant Star -- A star of 15 solar masses exhausts its hydrogen in about one-thousandth the lifetime of our sun. It proceeds through the red giant phase, but when it reaches the triple-alpha process of nuclear fusion, it continues to burn for a time and expands to an even larger volume. The much brighter, but still reddened star is called a red supergiant. Betelgeuse, at the shoulder of Orion, is the best-known example. Absolute luminosities may reach -10 magnitude compared to +5...
