Spectroscopy of Nine Cataclysmic Variable Stars [PDF]

Publications of the Astronomical Society of the Pacific, 2007
We present optical spectroscopy of nine cataclysmic binary stars, mostly dwarf novae, obtained primarily to determine orbital periods Porb. The stars and their periods are LX And, 0.1509743(5) d; CZ Aql, 0.2005(6) d; LU Cam, 0.1499686(4) d; GZ Cnc, 0 ...

Parallax and Distance Estimates for Twelve Cataclysmic Variable Stars [PDF]

The Astronomical Journal, 2008
We report parallax and distance estimates for twelve more cataclysmic binaries and related objects observed with the 2.4m Hiltner telescope at MDM Observatory. The final parallax accuracy is typically about 1 mas.

The absence of jets in cataclysmic variable stars [PDF]

Astronomy & Astrophysics, 2004
We show that the recently developed thermal model which successfully describes how jets are launched by young stellar objects, when applied to system containing disk-accreting white dwarfs naturally explain the otherwise surprising absence of jets in ...

Nine New Cataclysmic Variable Stars with Negative Superhumps [PDF]

The Astrophysical Journal, 2023
Negative superhumps (NSHs) are signals a few percent shorter than the orbital period of a binary star and are considered to originate from the reverse precession of the tilted disk.

ABOUT THREE CATACLYSMIC VARIABLE STARS

Odessa Astronomical Publications, 2017
In order to detect the new outbursts of the three cataclysmic variable TV Crv, NSV 1775, NSV 895, their positions was scanned on the plates of the Odessa collection of the sky service obtained for the period 1958 - 1988. The new outbursts were detected

Parallax and Distance Estimates for Fourteen Cataclysmic Variable Stars [PDF]

, 2003
I used the 2.4 m Hiltner telescope at MDM Observatory in an attempt to measure trigonometric parallaxes for 14 cataclysmic variable stars. Techniques are described in detail.

Exploring the SDSS Dataset with Linked Scatter Plots: I. EMP, CEMP, and CV Stars. [PDF]

Astrophys J Suppl Ser, 2017
We present the results of a search for extremely metal-poor (EMP), carbon-enhanced metal-poor (CEMP), and cataclysmic variable (CV) stars using a new exploration tool based on linked scatter plots (LSPs).

A spectrophotometric survey of cataclysmic variable stars

The Astronomical Journal, 1982
A sample of dwarf novae and other cataclysmic variable stars were observed using the multichannel spectrophotometer on the 5-m Hale reflector. A preliminary qualitative description of the continuum distributions is given and a discussion of the Balmer emission-line fluxes is made.

Searching for Cataclysmic Variable Stars in Unidentified X-Ray Sources [PDF]

Astrophysical Journal, 2022
We carry out a photometric search for new cataclysmic variable stars (CVs), with the goal of identification for candidates of AR Scorpii-type binary systems.
