The Orbital Period Changes for Novae
The Astrophysical JournalCataclysmic variables (CVs) are close interacting binaries in which a white dwarf accretes materials from a low-mass main-sequence companion. CVs can experience nova eruptions due to low mass transfer rates.

Analysis of cataclysmic variable star energy distributions
The Astronomical Journal, 1982 I analyze spectrophotometry of cataclysmic variable stars covering the wavelength range 0.32--1.1 ..mu..m. The contributions due to the cool secondary star and the accretion disk are separated, subject to the requirement that the spectrum attributed to the accretion disk be ''physically plausible.'' The results for individual stars, which are largely ...

The First Hours and Days of the 2021 Explosion of the Recurrent Symbiotic Nova RS Ophiuchii
The Astrophysical JournalThe accretion of matter onto a massive white dwarf (WD) can lead to repeated nuclear explosions on its surface over a timescale of years to decades. The seventh explosion of the recurrent symbiotic nova RS Ophiuchi (RS Oph) was recorded on 2021 August 8.

Optical identification of IGR J18308-1232 as a cataclysmic variable [PDF]
, 2008 We report on a spectroscopic analysis of optical sources inside the error circle of the XMM-Newton slew source XMMLS1 J183049.6-123218 (see Ibarra et al., ATel #1527), associated with the unidentifiedINTEGRAL source IGR J18308-1232 (Bird et al.

V1047 Cen: The First Z And-type Outburst Observed in the Classical Nova Binary
The Astrophysical JournalIn 2019, the classical nova V1047 Cen experienced an unusual outburst, the nature of which has not yet been clearly determined. In this paper, we show that the 2019 V1047 Cen outburst is of Z And-type—a type that is characteristic of and has so far been ...

The Astrophysical JournalAs cataclysmic variables (CVs) that have evolved past their minimum orbital period, period bouncers have been proposed to be a substantial fraction of the CV population, yet the observed number is significantly lower, posing the “missing bouncer” problem.

The Astronomical JournalWe present photometric and spectroscopic studies of a new WZ Sagittae (Sge)-type dwarf nova (DN) KSP-OT-202104a discovered by the Korea Microlensing Telescope Network Supernova Program. The source exhibits outburst amplitudes of ∼8 mag with a duration of

Stepanyan's star - A new eclipsing cataclysmic variable
The Astrophysical Journal, 1980 High-speed photometry of the nova-like variable Stepanyan's star shows a 3-hr 48-min orbital period marked by a 2.2-mag eclipse which spans orbital phases 0.91-0.09. The uneclipsed light is variable by typically 0.15 mag on time scales of minutes to seconds and shows no obvious modulation with orbital phase. Intermediate-band colors show an enhancement

Positive Superhumps in High-mass-ratio Cataclysmic Variables Driven by Apsidal Disk Precession
The Astrophysical Journal LettersPreviously it has been assumed that a cataclysmic variable (CV) disk can only become eccentric and display superhumps if the 3:1 resonance is located within the disk.
