Paper Spotlight: “Determinations of the 12C/13C Ratio for the Secondary Stars of AE Aquarii, SS Cygni, and RU Pegasi”

A Type Ia supernova is the complete explosion of a white dwarf that was being orbited by a secondary star prior to the explosion. Their high luminosity allows them to be used as the primary cosmological distance indicator, yet their progenitors remain unknown. It is almost certain that the progenitors of Type Ia supernovae are…
