Using the AstroSat spacecraft and the Neutron star Interior Composition Explorer (NICER) onboard the International Space Station (ISS), Indian astronomers have observed an X-ray binary known as GX 349+2. Results of the observational ...
An international team of astronomers has analyzed the data from the latest phase of the Sloan Digital Sky Survey (SDSS). They discovered eight new cataclysmic variables (CV) systems. The finding is reported in a paper published ...
Using INTEGRAL and Swift spacecraft, European astronomers have observed an unidentified X-ray source known as XTE J1906+090. Results of the observational campaign, presented May 11 on the arXiv preprint server, suggest that ...
An accretion disk is a colossal whirlpool of gas and dust that gathers around a black hole or a neutron star like cotton candy as it pulls in material from a nearby star. As the disk spins, it whips up powerful winds that ...

Using AstroSat and NuSTAR space telescopes, astronomers have observed an X-ray binary known as XTE J1739−285 during its recent period of bursting activity. Results of the observational campaign, published March 23 on the ...
By analyzing the data from the Hubble Space Telescope (HST), astronomers from the University of Bologna in Italy and elsewhere have found that the millisecond pulsar PSR J1835−3259B has a young white dwarf companion. The ...
A white dwarf star can explode as a supernova when its mass exceeds the limit of about 1.4 solar masses. A team led by the Max Planck Institute for Extraterrestrial Physics (MPE) in Garching and involving the University of ...

Using the Guillermo Haro Observatory (OAGH) in Mexico, astronomers have performed spectroscopic observations of a dwarf nova known as U Geminorum. Results of the observational campaign, published March 10 on the arXiv pre-print ...
Using the Imaging X-ray Polarimetry Explorer (IXPE), an international team of astronomers has conducted X-ray polarimetric observations of an accreting X-ray pulsar known as Vela X-1. Results of the observational campaign, ...
Using multiple telescopes, astronomers have detected two new magnetic cataclysmic variable systems of the polar subclass and determined their fundamental properties. The finding, which could help us better understand the ...
