Gamow-Teller strength distributions and neutrino energy loss rates due to chromium isotopes in stellar matter

Gamow-Teller transitions in isotopes of chromium play a consequential role in the presupernova evolution of massive stars. \(\beta\)-decay and electron capture rates on chromium isotopes significantly affect the time rate of change of lepton fraction (\(\dot{Y_{e}}\)). Fine-tuning of this parameter is one of the key for simulating a successful supernova explosion. The (anti)neutrinos produced as a result of electron capture and \(\beta\)-decay are transparent to stellar matter during presupernova phases. They carry away energy and this result in cooling the stellar core. In this paper we present the calculations of Gamow-Teller strength distributions and (anti)neutrino energy loss rates due to weak interactions on chromium isotopes of astrophysical importance. We compare our results with measured data and previous calculations wherever available.
