(Phys.org)—Astronomers have detected a new low-mass eclipsing binary star in an open cluster named NGC 2632, better known as the Beehive Cluster (or Praesepe). The newly identified binary, designated PTFEB132.707+19.810, ...
(Phys.org)—Astronomers have determined chemical abundances of several elements for six giant stars of a recently discovered stellar cluster known as Gaia1. The results, available in a paper published June 5 on arXiv.org, ...
(Phys.org)—An international team of astronomers led by Liliana Rivera Sandoval of the University of Amsterdam, Netherlands, has found 22 new cataclysmic variable stars in a globular cluster known as 47 Tucanae (47 Tuc for ...
European astronomers have recently studied the chemical composition of the low-mass globular cluster designated NGC 6362. Their detailed analysis of chemical abundances for 17 elements in the cluster provides important insights ...
All known black holes fall into two categories: small, stellar-mass black holes weighing a few Suns, and supermassive black holes weighing millions or billions of Suns. Astronomers expect that intermediate-mass black holes ...

(Phys.org)—The Hubble Space Telescope Hubble Tarantula Treasury Project (HTTP) survey has revealed new insights on the star formation history of the oldest star cluster in the Tarantula Nebula (also known as 30 Doradus), ...
(Phys.org)—Astronomers from Heidelberg University in Germany and the Observatory of Strasbourg in France have detected nine new open star clusters within 1,500 light years from the sun. The discovery, presented in a paper ...
(Phys.org)—A team of Brazilian astronomers, led by Denilso Camargo of the Federal University of Rio Grande do Sul in Porto Alegre, has discovered seven new embedded clusters located unusually far away from the Milky Way's ...
(Phys.org)—Australian astronomers have uncovered evidence of halo stars in two globular clusters residing in the Milky Way galaxy. According to a new study published on June 21 on the arXiv pre-print server, the globular ...
(Phys.org)—An international team of astronomers, led by Rodolfo Smiljanic of the Nicolaus Copernicus Astronomical Center in Toruń, Poland, has detected two new giant lithium-abundant stars in an old open cluster named ...
