On the orbital period distribution of cataclysmic variables
نویسندگان
چکیده
Using the latest compilation of cataclysmic variable orbital periods by Ritter & Kolb we argue against Verbunt’s conclusion that the period gap is not significant for novalike variables. We also discuss the relation of the VY Scl stars to the dwarf novae.

A search for brown - dwarf like secondaries in cataclysmic variables ⋆
We present VTL/ISAAC infrared spectroscopy of a sample of short orbital period cataclysmic variables which are candidates for harboring substellar companions. We have detected the K i and Na i absorption lines of the companion star in VY Aqr. The overall spectral distribution in this system is best fit with a M9.5 type dwarf spectra, implying a distance of 100 ± 10 pc. VY Aqr seems to fall far ...

متن کاملThe Lower Main Sequence and the Orbital Period Distribution of Cataclysmic Variable Stars
The color-magnitude diagram of the lower main sequence, as measured from a volume-limited sample of nearby stars, shows an abrupt downward jump between MV ∼ 12 and 13. This jump indicates that the observed mass-radius relationship steepens between 0.3 and 0.2 M⊙, but theoretical models show no such effect. It is difficult to isolate the source of this disagreement: the observational mass-radius...
متن کاملNova–induced Mass Transfer Variations
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. The effect is maximal if the specific angular momentum in the shell is the same as the specific orbital angular momentum of the white dwarf. We show analytically that in this...
متن کاملEvolutionary Effects of Irradiation in Cataclysmic Variables
The orbital evolution of cataclysmic variables in which the companion is illuminated by a fraction of the accretion luminosity consists of irradiation–driven limit cycles on thermal timescales, superimposed on a secular evolution toward shorter periods due to systemic angular momentum losses. We show that positive orbital period derivatives during bright phases are a natural consequence of the ...
