Tremendous outburst amplitude dwarf novae

open access: yesThe Astrophysical Journal, 1995
For many years, observers have noted the existence of a number of tremendous outburst amplitude dwarf novae. We present a summary of the known observational parameters for these exceptional systems. They show outburst amplitudes of 6-10 mag, have rare outbursts (interoutburst times being months to decades), and only seem to exist in dwarf novae with ...

Investigation of Superhumps in SU UMa-type Dwarf Novae Based on the Observations of TESS

open access: yesThe Astrophysical Journal, 2023
We report a superhumps analysis of seven SU UMa-type dwarf novae based on observations made by the Transiting Exoplanet Survey Satellite (TESS). Superhumps are seen during the superoutbursts of SU UMa-type dwarf novae. The monthlong data sets of TESS are

Symbiotic Star T CrB as an Extreme SU UMa–type Dwarf Nova

open access: yesThe Astrophysical Journal Letters, 2023
T CrB is a symbiotic recurrent nova that exhibits quiescent and active phases between its classical nova eruptions. The statistical properties of these active phases have been poorly studied thus far. Because of that their nature remained unknown.

Search for sub-TeV Neutrino Emission from Novae with IceCube-DeepCore

open access: yesThe Astrophysical Journal, 2023
The understanding of novae, the thermonuclear eruptions on the surfaces of white dwarf stars in binaries, has recently undergone a major paradigm shift. Though the bolometric luminosity of novae was long thought to arise directly from photons supplied by

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.

Study of Photometric Variability of Selected SU UMa Dwarf Novae

open access: yesActa Polytechnica CTU Proceedings, 2015
In this work we present time-resolved photometry of several poorly-studied dwarf novae during recent superoutbursts. Observations were made with a CCD, mounted on 50- and 60-cm telescopes of the Sternberg Astronomical Institute in Crimea in April - May ...
