Thermal Timescale Mass Transfer Rates in Intermediate-Mass X-ray Binaries [PDF]

open access: yes, 2007
Thermal timescale mass transfer generally occurs in close binaries where the donor star is more massive than the accreting star. The mass transfer rates are usually estimated in terms of the Kelvin-Helmholtz timescale of the donor star.

Nova-induced mass transfer variations [PDF]

open access: yes, 2001
We investigate variations of the mass transfer rate in cataclysmic variables (CVs) that are induced by nova outbursts. The ejection of nova shells leads to a spread of transfer rates in systems with similar orbital period.
