(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 ...
This 10.5-billion-year-old globular cluster, NGC 6496, is home to heavy-metal stars of a celestial kind! The stars comprising this spectacular spherical cluster are enriched with much higher proportions of metals—elements ...

(Phys.org)—Globular clusters have for a long time been considered as formed of stars with similar initial chemical composition, but recently, increasing evidence has emerged regarding their more complex nature. On Apr. ...
(Phys.org)—An international team of astronomers has recently detected two new so-called Be stars (non-supergiant stars with B spectral types and emission lines) residing in the open cluster NGC 6830, located some 5,300 ...
Young massive star clusters are systems of stars with more than about ten thousand solar-masses of material and ages less than about one hundred million years that are gravitationally bound together. In these clusters the ...
