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 ...
Astronomers from India have conducted a long-term photometric variability survey of an open cluster known as NGC 559. As a result, they detected 70 new variable stars in the field of this cluster. The finding is presented ...
Chinese astronomers have conducted a study of variable stars in the galactic open cluster NGC 1912 and its surrounding field, detecting 11 new variables in this cluster, including binary systems. The study was detailed in ...
Astronomers studying galaxy evolution have long struggled to understand what causes star formation to shut down in massive galaxies. Although many theories have been proposed to explain this process, known as "quenching," ...

By conducting photometric observations of the open cluster Stock 8 and its surrounding region, astronomers have identified 130 short-period variable stars, classifying 51 of them as members of the cluster. A paper detailing ...
An international team of astronomers has conducted multiwavelength observations of the star-forming region G345.5+1.5. The observational campaign discovered dozens of massive stars as well as protostellar and bound starless ...
Today, at the 233rd AAS meeting in Seattle, astronomers from the Sloan Digital Sky Survey (SDSS) announce that they have developed a new tool to find otherwise-hidden galaxy mergers in data from the Mapping Nearby Galaxies ...
