A Mini-Review of Accreting Pulsating White Dwarfs

open access: yesFrontiers in Astronomy and Space Sciences, 2021
The discovery in 1998 of a pulsating white dwarf in the cataclysmic variable GW Lib opened up a new avenue of exploration in the asteroseismology of white dwarfs.

WZ SGE STARS

open access: yesOdessa Astronomical Publications, 2007
The WZ Sge type stars is a rare subclass of the cataclysmic variables (CVs). It possesses the properties of both dwarf novae and recurrent novae. The WZ Sge stars have the shortest orbital periods (typically 80 - 90 minutes) known among the dwarf novae ...

Flares in dwarf novae [PDF]

open access: yesInternational Astronomical Union Colloquium, 1995
AbstractThis report provides a summary of flares observed visually in the dwarf novae V442 Cen, OY Car, TU Men and Z Cha. The flares precede an outburst by an average of around ten days.

The orbital and superhump periods of the dwarf nova HS 0417+7445 in Camelopardalis [PDF]

open access: yes, 2011
We present the 2005-2010 outburst history of the SU UMa-type dwarf HS 0417+7445, along with a detailed analysis of extensive time-series photometry obtained in March 2008 during the second ecorded superoutburst of the system.

Theory of Nova Outbursts and Type Ia Supernovae

open access: yesActa Polytechnica CTU Proceedings, 2015
We briefly review the current theoretical understanding of the light curves of novae. These curves exhibit a homologous nature, dubbed the universal decline law, and when time-normalized, they almost follow a single curve independently of the white dwarf

Theoretical Light-curve Models of the Symbiotic Nova CN Cha—Optical Flat Peak for 3 Yr

open access: yesThe Astrophysical Journal, 2023
CN Cha is a slow symbiotic nova characterized by a 3 yr long optical flat peak followed by a rapid decline. We present theoretical light curves for CN Cha, based on hydrostatic approximation, and estimate the white-dwarf (WD) mass to be ∼0.6 M _☉ for a ...

Classical Novae Masquerading as Dwarf Novae? Outburst Properties of Cataclysmic Variables with ASAS-SN

open access: yes, 2021
The unprecedented sky coverage and observing cadence of the All-Sky Automated Survey for SuperNovae (ASAS-SN) has resulted in the discovery and continued monitoring of a large sample of Galactic transients.

Observations of Eclipsing Dwarf Novae [PDF]

open access: yesInternational Astronomical Union Colloquium, 1987
AbstractHigh Speed Photometry of four eclipsing dwarf novae, Z Cha, OY Car, HT Cas and IP Peg, is used to determine the orbital parameters and the masses of the two stars in each system. The mass ratio, q, and inclination, i, are found by constraining theoretical stream trajectories (Lubow and Shu 1975) to pass through the observed light centre of the ...

MULTI-FREQUENCY STUDY OF SYMBIOTIC NOVAE

open access: yesOdessa Astronomical Publications, 2017
Symbiotic novae are subclass of symbiotic stars - interacting binaries with wide orbits, whose photometric history is characterized by a single nova- like outburst lasting decades and caused by a thermonuclear runaway on the surface of a wind accreting ...
