Reduced Beta Decay Rates of Iron Isotopes for Supernova Physics Available to Purchase

During the late phases of stellar evolution beta decay on iron isotopes, in the core of massive stars, plays a crucial role in the dynamics of core‐collapse. The beta decay contributes in maintaining a ‘respectable’ lepton‐to‐baryon ratio $(Ψe)$ of the core prior to collapse which results in a larger shock energy to power the explosion. It is indeed a fine tuning of the parameter $Ψe$ at various stages of supernova physics which can lead to a successful transformation of the collapse into an explosion. The calculations presented here might help in fine‐tuning of $Ψe$ for the collapse simulators of massive stars.
