Fig. 4.


Predicted mass accretion rate, , of Bildsten et al. (2006) as a function of orbital period, where the accretor is a 0.65 M white dwarf and the blue track has a cool donor star and the red track a hot donor star. We show the mass transfer rate derived using a white dwarf plus accretion disc model, GDR2 parallax data and multi-wavelength photometric measurements.
