Polish astronomers have performed photometric observations of a short-period variable star known as NSVS 2983201. They have found that the object is a contact binary system with a mass ratio of about 0.36. The finding was ...
Using the Indian Astronomical Observatory (IAO) in Hanle, India, astronomers have observed a globular cluster known as NGC 7006. Results of the study, presented December 9 on the arXiv pre-print server, yield important insights ...
Using the 1-m Ritchey–Chrétien–Coudé telescope of the Konkoly Observatory in Budapest, Hungary and NASA's Transiting Exoplanet Survey Satellite (TESS), Hungarian astronomers have observed a variable star known as GD ...
If humanity is ever going to find life on another planet in the solar system, it's probably best to know where to look. Plenty of scientists have spent many, many hours pondering precisely that question, and plenty have ...

Italian astronomers have reported the discovery of a new lithium-rich galactic Cepheid star, identified by high-resolution spectroscopic observations. The newfound object, designated V363 Cas, is the fifth lithium-rich classical ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have detected Beta Cephei-type pulsations in an eclipsing binary system known as V453 Cygni. The finding, detailed in a paper published May 15 on arXiv.org, ...
The interiors of stars are largely mysterious regions because they are so difficult to observe directly. Our lack of understanding about the physical processes there, like rotation and the mixing of hot gas, introduces considerable ...
