We propose a physically motivated and self-consistent prescription for themodeling of transient neutron star (NS) low-mass X-ray binary (LMXB)properties, such as duty cycle (DC), outburst duration and recurrence time. Weapply this prescription to the population synthesis (PS) models of field LMXBspresented by Fragos et al. (2008), and compare the transient LMXB population tothe Chandra X-ray survey of the two elliptical galaxies NGC 3379 and NGC 4278,which revealed several transient sources (Brassington et al., 2008, 2009). Weare able to exclude models with a constant DC for all transient systems, whilemodels with a variable DC based on the properties of each system are consistentwith the observed transient populations. We predict that the majority of theobserved transient sources in these two galaxies are LMXBs with red giantdonors. Our comparison suggests that LMXBs formed through evolution ofprimordial field binaries are dominant in globular cluster (GC) poor ellipticalgalaxies, while they still have a significant contribution in GC rich ones.
