A research team from the Yunnan Observatories of the Chinese Academy of Sciences has conducted a study on the binary fraction of blue horizontal-branch (BHB) stars. Their findings, recently published ...

Blue stragglers are anomalously massive core hydrogen-burning stars that, according to the theory of single star evolution, should not exist. They are suspected to form in mass-enhancement processes, ...

Most of what we know about the universe comes from studies on stars, and about half of the stars are found to be in binary systems. The close binary interaction between the stellar components may ...

Blue stragglers are anomalously luminous core hydrogen-burning stars formed through mass-transfer in binary/triple systems and stellar collisions. Their physical and evolutionary properties are ...

Scientists analyzed over a decade's worth of data about 16 young supermassive stars orbiting the supermassive black hole at the center of the Milky Way galaxy. Supermassive stars typically are formed ...
