Web17 giu 2009 · Specifically, I’m looking for the range within a galaxy that a supernova would pose a mass extinction event to animal life. I’ve heard that some Type 1a Supernova can be a potential threat to humans within a range as large as 3300 LY. However, the terms of threat to humans were somewhat vague in all the sources I’ve read. Webrameters (explosion energy E, mass of the envelope expelled M and pre-supernova radius R) on the other. The correlation is used, together with adopted distances from the expanding photosphere method, to estimate E, M and R for a dozen well-observed SNIIP.

The majority of massive stars are likely members of binary star systems (e.g., Abt and Levy, 1978 ). Furthermore, close binary systems are likely the progenitors of many core-collapse SNe. mouthpiece nfl
