主題: Veiled supernovae provide clue to stellar evolution 作者: peter 於 2018-09-05 10:18:16 https://www.sciencedaily.com/releases/2018/09/180904103251.htm
At the end of its life, a red supergiant star explodes in a hydrogen-rich supernova. By comparing observation results to simulation models, an international research team found that in many cases this explosion takes place inside a thick cloud of circumstellar matter shrouding the star. This result completely changes our understanding of the last stage of stellar evolution. |
