Influence of the initial orbital period and accretion efficiency on the low-mass binary evolution

Influence of the initial orbital period and accretion efficiency on the low-mass binary evolution

This paper presents detailed evolutionary models of low-mass binary systems (1.25 + 1 M⊙) with initial orbital periods of 10, 50 and 100 days and accretion efficiency of 10%, 20%, 50%, and a conservative assumption. All models are calculated with the MESA (Modules for Experiments in Stellar...
