The Periods of Cataclysmic Variables
نویسنده
چکیده
The present status of the period studies of cataclysmic variables is briefly reviewed, mainly from the observational point of view. A few comments on individual objects include EM Cyg, Z Cha, WZ Sge and AM CVn.

ar X iv : a st ro - p h / 05 11 46 1 v 1 15 N ov 2 00 5 Spectroscopy of Four Cataclysmic Variables with Periods above 7 Hours 1
We present spectroscopy of four cataclysmic variables. Using radial velocity measurements, we find orbital periods Porb for the first time. The stars and their periods are GY Hya, 0.347230(9) d; SDSS J204448-045929, 1.68(1) d; V392 Hya, 0.324952(5) d; and RX J1951.7+3716, 0.492(1) d. We also detect the spectra of the secondary stars, estimate their spectral types, and derive distances based on ...

متن کاملOn the orbital period distribution of cataclysmic variables
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.
متن کاملA new absolute magnitude calibration with 2 MASS for cataclysmic variables
A new absolute magnitude calibration with 2MASS for cataclysmic variables Abstract Using reliable trigonometric measurements, we find that the absolute magnitude of cataclysmic variables depends on the orbital period and de-reddened (J − H) 0 and (H −K s) 0 colours of 2MASS (Two Micron All Sky Survey) photometric system. The calibration equation covers the ranges 0.032 d < P orb ≤ 0.454 d , −0....
متن کاملEvidence of Precession of the White Dwarf in Cataclysmic Variables
Cataclysmic Variables (CV) are close binary systems, in which the primary, the more massive star, is a white dwarf. CVs usually exhibit a number of periodicities, most of which are now understood. However, recently, a new phenomenon was discovered that does not fit the standard picture. Two objects have been discovered to show periods that are much longer than orbital, and have no relation to i...
