1. Absolute magnitudes of cataclysmic variables
ID:
ivo://CDS.VizieR/J/other/NewA/12.446
Title:
Absolute magnitudes of cataclysmic variables
Short Name:
J/other/NewA/12.
Date:
21 Oct 2021
Publisher:
CDS
Description:
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-Ks)_0_ colours of 2MASS (Two Micron All Sky Survey) photometric system. The calibration equation covers the ranges 0.032d<P_orb_<=0.454d, -0.08<(J-H)_0_<=1.54, -0.03<(H-Ks)_0_<=0.56 and 2.0<M_J_<11.7; It is based on trigonometric parallaxes with relative errors of ({sigma}{pi}/{pi})<=0.4. By using the period-luminosity-colours (PLCs) relation, we estimated the distances of cataclysmic variables with orbital periods and 2MASS observations and compared them with distances found from other methods. We suggest that the PLCs relation can be a useful statistical tool to estimate the distances of cataclysmic variables.

Title:
A VLA survey of magnetic CVs. I. The data
Short Name:
J/AJ/154/252
Date:

Publisher:
CDS
Description:
The Jansky Very Large Array was used to observe 121 magnetic cataclysmic variables (MCVs). We report radio detections of 18 stars. Thirteen are new radio sources, increasing the number of MCVs that are radio sources by more than twofold, from 8 to 21. Most detections are at 8.7 GHz (X-band) with a lesser number at 5.4 and 21.1 GHz (C- and K-bands). With the exception of AE Aqr, whose flux density is typically >5 mJy, the flux densities are in the range of 24-780 {mu}Jy. Thirteen of the detections show highly circularly polarized emission, which is characteristic of electron-cyclotron maser emission. The data suggest that MCVs could possibly be divided into two classes of radio emitters: those dominated by weakly polarized gyrosynchrotron emission and those by highly polarized electron-cyclotron maser emission.

Description:
This compilation contains the current content (as of 1 September 1993) of the Catalogue of cataclysmic binaries, low-mass X-ray binaries and related objects (previous version: A&AS 85, 1179, catalogue <V/59>) Please refer to the introduction (file "intro.tex") for a more complete introduction.
5. Cataclysmic Binaries and LMXB Catalogue
ID:
ivo://CDS.VizieR/V/99
Title:
Cataclysmic Binaries and LMXB Catalogue
Short Name:
V/99
Date:
21 Oct 2021
Publisher:
CDS
Description:
Cataclysmic Binaries are semi-detached binaries consisting of a white dwarf or a white dwarf precursor primary and a low-mass secondary which is filling its critical Roche lobe. The secondary is not necessarily unevolved, it may even be a highly evolved star as for example in the case of the AM CVn-type stars. Low-Mass X-Ray Binaries are semi-detached binaries consisting of either a neutron star or a black hole primary, and a low-mass secondary which is filling its critical Roche lobe. Related Objects are detached binaries consisting of either a white dwarf or a white dwarf precursor primary and of a low-mass secondary. The secondary may also be a highly evolved star. The catalogue lists coordinates, apparent magnitudes, orbital parameters, stellar parameters of the components and other characteristic properties of 318 cataclysmic binaries, 47 low-mass X-ray binaries and 49 related objects with known or suspected orbital periods together with a comprehensive selection of the relevant recent literature. In addition the catalogue contains a list of references to published finding charts for 394 of the 414 objects. A cross-reference list of alias object designations concludes the catalogue. Literature published before 30 June 1997 has, as far as possible, been taken into account. This catalogue supersedes the 5th edition (catalogue <V/59>) and the updated list by Ritter and Kolb (1995; catalogue <V/82>).

9. Cataclysmic variables from CRTS
ID:
ivo://CDS.VizieR/J/MNRAS/441/1186
Title:
Cataclysmic variables from CRTS
Short Name:
J/MNRAS/441/1186
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present 855 cataclysmic variable candidates detected by the Catalina Real-time Transient Survey (CRTS) of which at least 137 have been spectroscopically confirmed and 705 are new discoveries. The sources were identified from the analysis of five years of data, and come from an area covering three quarters of the sky. We study the amplitude distribution of the dwarf novae cataclysmic variables (CVs) discovered by CRTS during outburst, and find that in quiescence they are typically 2mag fainter compared to the spectroscopic CV sample identified by the Sloan Digital Sky Survey. However, almost all CRTS CVs in the SDSS footprint have ugriz photometry. We analyse the spatial distribution of the CVs and find evidence that many of the systems lie at scale heights beyond those expected for a Galactic thin disc population. We compare the outburst rates of newly discovered CRTS CVs with the previously known CV population, and find no evidence for a difference between them. However, we find significant evidence for a systematic difference in orbital period distribution. We discuss the CVs found below the orbital period minimum and argue that many more are yet to be identified among the full CRTS CV sample. We cross-match the CVs with archival X-ray catalogues and find that most of the systems are dwarf novae rather than magnetic CVs.
10. Cataclysmic variables from LAMOST DR3
ID:
ivo://CDS.VizieR/J/other/RAA/18.68
Title:
Cataclysmic variables from LAMOST DR3
Short Name:
J/other/RAA/18.6
Date:

Publisher:
CDS
Description:
Big data in the form of stellar spectra from the spectroscopic survey associated with the Large Sky Area Multi-object Fiber Spectroscopic Telescope (LAMOST) are important for studying properties of cataclysmic variables (CVs). By cross matching the catalogs of CVs compiled with LAMOST DR3, acquired from October 2011 to July 2015, we obtained the first spectroscopic catalog for CVs observed by LAMOST with high signal to noise ratio, above 8. By integrating line profiles, their equivalent widths (EWs) of the H{alpha}, H{beta}, H{gamma} and H{delta}, as well as HeI 5876 and 6678{AA} lines, were calculated. There were 74 stellar spectra from 48 known CVs and three spectra from three new CV candidates. At the same time, we also collected their previously published EWs. Thirty-three objects had repeated spectra and 30 stars showed spectral variability in the H{alpha} line. Moreover, we carried out photometric follow-up studies for five CVs (UU Aqr, TT Tri, PX And, BP Lyn and RW Tri). We obtained nine new light curves and revised their linear ephemerides. For RW Tri, there is a possible oscillation with an amplitude of 0.0031(2) days and a period of 47.6+/-0.4 years, which might be caused by a third body (brown dwarf) or magnetic activity cycle.
