The CV Period Minimum
Ulrich Kolb, Isabelle Baraffe
Using improved, up-to-date stellar input physics tested against observations of low-mass stars and brown dwarfs we calculate the secular evolution of low-mass donor CVs, including…

Are the red dwarfs in cataclysmic variables main-sequence stars?
K. Beuermann, I. Baraffe, U. Kolb +1
We show that the secondaries in short-period cataclysmic variables with orbital periods hr are close to the solar-abundance main sequence defined by single field stars. In…

The CV period gap: still there
U. Kolb, A. R. King, H. Ritter
We consider a recently-proposed alternative explanation of the CV period gap in terms of a revised mass-radius relation for the lower main sequence. We show that no such thermal-eq…
