Expanded calculations of pn-QRPA electron capture rates on ${}^{55}$Co for presupernova and supernova physics

Abstract

Due to its abundance and its relatively high capture rates, ${}^{55}$Co is one of the key nuclide that can control the dynamics of core collapse of a massive star. Previously we introduced our microscopic calculations of capture rates on ${}^{55}$Co using the proton-neutron quasi-particle random phase approximation (pn-QRPA) theory. Here we present for the first time an expanded calculation of the electron capture rates on ${}^{55}$Co on an extensive temperature-density scale. These type of scale is appropriate for interpolation purposes and of greater utility for simulation codes.
