A local recent supernova: evidence from X rays, 26Al radioactivity and cosmic rays.
Abstract
Several lines of astrophysical investigation suggest that the solar system is immersed in a low-density medium of high temperature (n ≡4×10-3cm-3, T ≡106K) extending roughly 100 pc from the Sun, and that the latter medium was reheated by a supernova event some tens of parsecs from the Sun about 105yr ago. This paper reviews observational evidence from cosmic ray isotopic abundance studies indicating that solar system material may have been contaminated by a recent local supernova.
