Abstract: We investigated the effect of different angular momentum loss during the mass transfer of long-period sdB binaries by implementing a variable angular momentum loss efficiency parameter in MESA code. Our preliminary results show the impact on the mass ratio, orbital period, and metallicity. In particular, the number of long-period sdBs produced is reduced for higher angular momentum loss efficiency.
