An evolutionary channel towards the accreting millisecond pulsar
... In the MESA code, we consider three types of orbital-angularmomentum loss during the evolution of LMXBs: (1) gravitationalwave radiation; (2) magnetic braking: we adopt the standard magnetic braking prescription given by Rappaport, Verbunt & Joss (1983), and take γ = 4; (3) mass-loss: the mass-loss ...
