الوصف: | We estimate the mass of the compact object in the gamma-ray binaries LSI+61303 and MWC 148, using the latest data for the inclination, orbital motion and assuming that the orbital plane coincides with the equatorial plane of the Be star. For LSI+61303 we find the mass of the compact object to be most likely in the range 1.3 M_sun < M_2 < 2.0 M_sun, which means that it is probably a neutron star. For MWC 148, we find the mass of the compact object in a higher range, 2.1 M_sum < M_2 < 7.3 M_sun, which increases the chances for this system to host a black hole companion.
