Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered two new young planetary systems. They found that two stars not older than 320 million years, namely TOI-251 and TOI-942, are orbited by ...
An international team of astronomers reports the discovery of a new eclipsing binary system using NASA's Kepler spacecraft during its prolonged mission known as K2. The system, designated EPIC 216747137, appears to be a post-common-envelope ...
Using India's AstroSat space observatory and ESA's XMM-Newton spacecraft, astronomers have carried out X-ray observations of a symbiotic recurrent nova known as V3890 Sgr during its outburst in 2019. Results of this study, ...
Astronomers from the California Institute of Technology and elsewhere report the detection of a new eclipsing detached double white dwarf binary. The system, designated ZTF J2243+5242 has an orbital period of below 10 minutes, ...
Using data from the Rossi X-ray Timing Explorer (RXTE) satellite, astronomers from the Florida Institute of Technology have discovered a quasi-periodic oscillation (QPO) in the galaxy NGC 4945. The finding, reported in a ...
An international team of astronomers has performed photometric observations of a binary system known as CXOGBS J175553.2-281633. Results of the study indicate that the object is a cataclysmic variable system. The finding ...
