Abstract
AM CVn-type stars and ultra-compact X-ray binaries are extremely interesting
semi-detached close binary systems in which the Roche lobe filling component
is a white dwarf transferring mass to another white dwarf, neutron star or a
black hole. Earlier theoretical considerations show that there is a maximum
mass ratio of AM CVn-type binary systems (qmax ? 2/3) below which the mass
transfer is stable. In this paper we derive slightly different value for qmax
and more interestingly, by applying the same procedure, we find the maximum
expected white dwarf mass in ultra-compact X-ray binaries.
