Secondary Stars in CVs: The Theoretical Perspective [PDF]
, 1999 We apply the new generation of theoretical models of low-mass stars to secondaries in CVs, focussing on systems above the period gap. The models confirm that the spectral type should be a good indicator of the donor mass. The orbital period-spectral type
