Even with eclipsing binaries, measuring the properties of stars is no easy task. Stars are deformed as they rotate and pull ...

Astronomers have made a groundbreaking discovery that defies the conventional understanding of planetary formation in binary ...

The article discusses the challenges in measuring the basic properties of stars due to their astronomical distances. It ...

Astronomers have identified a rare type of binary star system containing a rapidly spinning millisecond pulsar and a helium star companion, formed via common envelope evolution. Although such ...

Due to its high density of stars, there should in theory be many binary stars. However, the five known binary stars are actually located in other, more distant regions, while none have yet been ...

Astronomers confirmed the first case of a star surviving a black hole encounter, challenging long-held beliefs about tidal disruption events.

The researchers are already excited to get a closer glimpse of a similar binary star system, such as HD 59686, which also hosts an enormous gas giant with six times the mass of Jupiter.

When the binary star system disappears, one single star will remain. "We calculated that it could be tomorrow, next week or maybe in a million years -- which, from an astrophysical point of view ...

Binary star systems, or pairs of stars that orbit around each other, are very common. In fact, it’s estimated that 85% of stars in the universe have at least one companion.
