Binary star - Wikipedia
A binary star or binary star system is a system of two stars that are gravitationally bound to and in orbit around each other. Binary stars in the night sky that are seen as a single object to the naked eye are often resolved as separate stars using a telescope, in …
What are binary stars? | Space
2023年11月22日 · A visual binary is a binary star system in which the stars can be individually seen as separate bodies in a telescope from Earth.
Multiple Star Systems - NASA Science
Some multiple star systems include three stars or more, their orbits intricately intertwined by gravity. As many as seven stars have been observed in a single system. Like binaries, triple-star systems can host planets.
Binary star | Definition, Types, & Facts | Britannica
3 天之前 · binary star, pair of stars in orbit around their common centre of gravity. A high proportion, perhaps one-half, of all stars in the Milky Way Galaxy are binaries or members of more complex multiple systems.
Binary system - Wikipedia
The most common kinds of binary system are binary stars and binary asteroids, but brown dwarfs, planets, neutron stars, black holes and galaxies can also form binaries. A multiple system is similar but consists of three or more objects, for example trinary stars and trinary asteroids.
Introduction to Binary Stars - Australia Telescope National Facility
A binary system is simply one in which two stars orbit around a common centre of mass, that is they are gravitationally bound to each other. Actually most stars are in binary systems. Perhaps up to 85% of stars are in binary systems with some in triple or even higher-multiple systems.
The Astrophysics Spectator: Binary Star Systems
2008年4月4日 · Binary stars, when they are widely separated, are described as the action of Newtonian gravity on two point-masses. Each star moves in an elliptical orbit, and the motion of one star relative to the other also traces an ellipse.
23.5 The Evolution of Binary Star Systems - OpenStax
But as we saw in The Stars: A Celestial Census, it now appears that as many as half of all stars may develop in binary systems—those in which two stars are born in each other’s gravitational embrace and go through life orbiting a common center of mass.

6 天之前 · In our close vicinity, we also find binary stars. Thus, Alpha Centauri is a binary system of solar-like stars, located just 4.3 light-years from the Sun, and appearing as a visual binary with an orbital period of about 80 years (Heintz, 1982; Pourbaix & Boffin, 2016).In fact, it is likely that Alpha Centauri forms with the closest star to the Sun, Proxima Centauri, a triple system!
Binary Star Systems | Formation, Dynamics & Evolution
2024年5月28日 · Binary star systems, consisting of two stars orbiting a common center of mass, are among the most common celestial phenomena in our galaxy. The dynamics and evolution of these systems provide crucial insights into stellar processes and …
