GSC 4560–02157: a new long-period eclipsing cataclysmic variable star [PDF]

, 2015
We study the newly discovered variable star GSC 4560–02157. CCD photometry was performed in 2013–2014 at the Tien Shan Astronomical Observatory, and a spectrum was obtained with the 6-m telescope of the Special Astrophysical Observatory in June, 2014 ...

TT Arietis – observations of a Cataclysmic Variable Star with the MOST Space Telescope [PDF]

, 2009
We measured the photometric flux of the cataclysmic variable TT Arietis (BD+14 341) using the MOST space telescope. Periodic oscillations of the flux reveal the orbital period as well as other features of this binary system. We applied a Discrete Fourier

MULTICOLOR PHOTOMETRY OF CATACLYSMIC VARIABLE STAR BG TRIANGULUM [PDF]

BOOK OF ABSTRACTS: XIV Serbian-Bulgarian Astronomical Conference
In this study we present the multicolor UBVRI observations of the cataclysmic variable star BG Tri during its superhump activity. The variability amplitudes and color indices during the active and quiescent phases of the system are determined and ...

The intermediate polar cataclysmic variable GK Persei 120 years after the nova explosion: a first dynamical mass study [PDF]

Monthly notices of the Royal Astronomical Society, 2021
We present a dynamical study of the intermediate polar and dwarf nova cataclysmic variable GK Persei (Nova Persei 1901) based on a multisite optical spectroscopy and R-band photometry campaign.

A Stellar Constraint on Eddington-inspired Born–Infeld Gravity from Cataclysmic Variable Binaries [PDF]

Astrophysical Journal, 2021
Eddington-inspired Born–Infeld gravity is an important modification of Einstein’s general relativity, which can give rise to nonsingular cosmologies at the classical level, and avoid the end-stage singularity in a gravitational collapse process.
