WebMass loss For massive stars, mass loss in stellar winds means that the present mass is smaller than the initial mass. These difficulties mean that although the local IMF is well … Webray luminosity but also on the mass of the BH. While the masses of BH XRBs are typically around ∼10M , this mass-term provides an additional uncertainty compared to the accretion rate measure based on the radio luminosity. Thus, we will estimate the accretion rate from the radio luminosity if quasi-simultaneous measurements
