To Explode or Not Explode? An Analysis of the Explodability of Binary and Single Stars
Year: 2024
Type: article
Abstract: Most massive stars in our universe are born in binary systems, and yet their fates are quite uncertain, due to a poor understanding of their evolution. It is well known, however, that the density profile of a collapsing core, particularly at the interface between silicon and oxygen shells, is important when determining the explodability of a star. While this has been studied for single stars, it has been rarely studied for binary stars. In this note, we explore the explodability of single and binary stars using self-consistent supernova simulations. We study the differences in the silicon–oxygen interface and compactness of the progenitor stars and how they affect the explodability. We find that binary-stripped stars with initial masses above 37 M ⊙ are not as explodable as their single-star counterparts.
