A team of astrophysicists from Nanjing University and University of Bonn have demonstrated that, rather than being random, the mass of new stars born inside a star cluster is actually governed by a defined process of self-regulation. Their work has been published in the journal Research in Astronomy and Astrophysics.
How galaxy size shapes newborn stars
When a galaxy welcomes new stars, they are usually formed in star clusters inside vast gas clouds...

Researchers provide the first plausible explanation to why one of the most massive black hole pairs observed to date by gravitational waves also seemed to merge on a non-circular orbit. Their suggested solution, now published in Nature, involves a chaotic triple drama inside a giant disk of gas around a super massive black hole in a galaxy far, far away.
Black holes are one of the most fascinating objects in the Universe, but our knowledge of them is still limited — especi...

Finding lost star siblings. Star clusters have been part of the Imaginarium of human civilization for millennia. The brightest star clusters to Earth, like the Pleiades, are readily visible to the naked eye. A team has now revealed the existence of massive stellar halos, termed coronae, surrounding local star clusters.
“Clusters form big families of stars that can stay together for large parts of their lifetime...

An image of the Wild Duck Cluster was captured by the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile. The blue stars at the center of the image are the stars of the cluster. Every star in the Wild Duck Cluster is roughly 250 million years old. Older, redder stars surround the cluster.

Do star clusters harbor many generations of stars or just one? Scientists have long searched for an answer and, thanks to the University of Arizona’s MMT telescope, found one in the Wild Duck Cluster, where stars spin at different speeds, disguising their common age.
In a partnership between the UA and the Korean Astronomy and Space Science Institute, a team of Korean and Belgian astronomers used UA instruments to solve a puzzle about flocks of stars call...
