An international team of astronomers has conducted spectroscopic and photometric observations of a cataclysmic variable (CV) known as V1460 Her. Results of the study indicate that the system consists of a fast-spinning white ...
The enigmatic variations of light in a binary system, located in Sagittarius constellation, could be explained by the presence of a variable gas disc around a hot star that revolves around a cooler star. These are the conclusions ...

Using the AstroSat spacecraft, Indian astronomers have identified thermonuclear X-ray bursts on the low-mass X-ray binary (LMXB) Cygnus X-2. The finding, reported in a paper published August 17 on the arXiv preprint server, ...
Using NASA's Kepler spacecraft, astronomers have detected a new bright transient event. After further analysis, the newly found transient source turned out to be a cataclysmic variable (CV) star. The finding is detailed in ...
Astronomers have investigated a nearby cataclysmic variable system known as CTCV J2056-3014 using ESA's XMM-Newton satellite. Results of the study, presented in a paper published July 28 on the arXiv pre-print repository, ...
The direct detection of gravitational waves from at least eleven sources during the past five years has offered spectacular confirmation of Einstein's model of gravity and space-time, while the modeling of these events has ...
