An international team of astronomers has performed a comprehensive spectroscopic and photometric study of a pulsating eclipsing binary star known as AI Hya. Results of the study, published January 11 on the arXiv pre-print ...
One of the biggest achievements of quantum physics was recasting our vision of the atom. Out was the early 1900s model of a solar system in miniature, in which electrons looped around a solid nucleus. Instead, quantum physics ...

Russian astronomers have performed spectroscopic and photometric observations of a peculiar eclipsing polar known as BS Tri. Result of this observational campaign, presented in a paper published December 23 on arXiv.org, ...
Astronomers from Argentina and France have investigated the evolutionary history of an eccentric high-mass X-ray binary known as GX 301-2. Results of the study, published December 22 on the arXiv pre-print repository, deliver ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new "hot Jupiter" exoplanet. The newfound alien world, estimated to be nearly three times as massive as Jupiter, ...
For the first time, astronomers have spotted an exoplanet whose orbit is decaying around an evolved, or older, host star. The stricken world appears destined to spiral closer and closer to its maturing star until collision ...
