(Phys.org) —A team of researchers working in China has found evidence to suggest that stars that exist in metal-rich galactic areas tend to explode more violently when they go supernova, than do stars that explode in less ...
A group of researchers led by Melina Bersten (Kavli IPMU) has presented evidence that the yellow supergiant (YSG) star found at the location of supernova SN 2011dh in the famous nearby galaxy M51 was indeed the SN progenitor, ...
