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 ...
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, ...
Using the NICER instrument, astronomers have conducted a detailed X-ray spectral and variability study of an outburst from an X-ray transient source known as MAXI J1727-203. Results of this investigation could shed more light ...
An exploding white dwarf star blasted itself out of its orbit with another star in a "partial supernova" and is now hurtling across our galaxy, according to a new study from the University of Warwick.

German astronomers have conducted photometric observations of a cataclysmic variable (CV) star known as PTF1J2224+17. Results of the observational campaign confirm that this object is a polar, as suggested by previous studies. ...
A team of researchers, led by astrophysicist Sumner Starrfield of Arizona State University, has combined theory with both observations and laboratory studies and determined that a class of stellar explosions, called classical ...
