(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 metal-rich areas. In their paper published in the journal Science, describing their research, the team details how after analyzing data from the remnants of 188 type 1a supernovas, they found that those stars that existed in metal-rich areas and maybe in younger systems, tended to produce more violent explosions and associated diverse spectral features.
