VY Sculptoris stars as magnetic cataclysmic variables [PDF]

open access: yesAstronomy and Astrophysics, 2002
AbstractWe show that VY Scl stars must be magnetized in order to account for the absence of outbursts during their low and intermediate states. Absence of outbursts during low states requires only rather low magnetic moments but in systems in which the drops and rises of luminosity are slower than it takes for the accretion disc to adjust viscously to ...

Accretion in Cataclysmic Variable Stars [PDF]

open access: yes, 2005
We consider accretion onto the white dwarfs in cataclysmic variables in relation to nova eruptions, dwarf nova outbursts, hibernation and non-radial oscillations.

The absence of jets in cataclysmic variable stars [PDF]

open access: yesAstronomy and 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 cataclysmic variable stars.

The winds in cataclysmic variable stars [PDF]

open access: yesAIP Conference Proceedings, 1986
Ultraviolet spectrophotometry of two dwarf novae, CN Ori and RX And, at various phases of their outburst cycles, confirms that the far UV flux increases dramatically about 1–2 days after the optical outburst begins. At this time the UV spectral line profiles indicate the presence of a high velocity wind.

ABOUT THREE CATACLYSMIC VARIABLE STARS

open access: yesOdessa 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

An X-Ray-dim “Isolated” Neutron Star in a Binary?

open access: yesThe Astrophysical Journal Letters, 2023
We report the discovery of a dark companion to 2MASS J15274848+3536572 with an orbital period of 6.14 hr. Combining the radial velocity from LAMOST observations and modeling of the multiband light curve, one obtains a mass function of ≃0.131 M _⊙ , an ...

Cataclysmic Variable Stars [PDF]

open access: yesInternational Astronomical Union Colloquium, 1984
AbstractThe properties of cataclysmic variable outbursts are reviewed, and interpreted in terms of dynamical instabilities by the red component, and subsequent evolution of the white dwarf accretion disc subject to a mass transfer burst in the transfer stream.

The donor stars of cataclysmic variables [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2006
Abstract We carefully consider observational and theoretical constraints on the global properties of secondary stars in cataclysmic variable stars (CVs). We then use these constraints to construct and test a complete, semi-empirical donor sequence for CVs with orbital periods Porb≤ 6 h.
