Study of Photometric Variability of Selected SU UMa Dwarf Novae
Acta 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 ...

Theory of Nova Outbursts and Type Ia Supernovae
Acta 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
The 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 ...

Discovery of a new photometric sub-class of faint and fast classical novae [PDF]
, 2010 We present photometric and spectroscopic follow-up of a sample of extragalactic novae discovered by the Palomar 60-inch telescope during a search for "Fast Transients In Nearest Galaxies" (P60-FasTING). Designed as a fast cadence (1-day) and deep (g < 21

Two-dimensional simulations of mixing in classical novae: The effect of white dwarf composition and mass [PDF]
Astronomy & Astrophysics, 2018 Context. Classical novae are explosive phenomena that take place in stellar binary systems. They are powered by mass transfer from a low-mass main sequence star onto either a CO or ONe white dwarf.

Eruptive novae in symbiotic systems [PDF]
Monthly notices of the Royal Astronomical Society, 2023 We conduct numerical simulations of multiple nova eruptions in detached, widely separated symbiotic systems that include an asymptotic giant branch (AGB) companion to investigate the impact of white dwarf (WD) mass and binary separation on the ...

Infrared spectroscopy of cataclysmic variables: III. Dwarf novae below the period gap and novalike variables [PDF]
, 2000 We present K-band spectra of the short-period dwarf novae YZ Cnc, LY Hya, BK Lyn, T Leo, SW UMa and WZ Sge, the novalike variables DW UMa, V1315 Aql, RW Tri, VY Scl, UU Aqr and GP Com, and a series of field dwarf stars with spectral types ranging from K2-

Observations of Eclipsing Dwarf Novae [PDF]
International 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 ...

Statistical properties of dwarf novae-type cataclysmic variables: the outburst catalogue [PDF]
, 2015 The outburst catalogue contains a wide variety of observational properties for 722 dwarf nova (DN)-type cataclysmic variables (CVs) and 309 CVs of other types from the Catalina Real-time Transient Survey.

MULTI-FREQUENCY STUDY OF SYMBIOTIC NOVAE
Odessa 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 ...
