Binary star - Wikipedia
网页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 which case they are called visual binaries.
NASA’s Fermi Finds Record-breaking Binary in Galaxy Next Door
网页2016年9月29日 · Using data from NASA’s Fermi Gamma-ray Space Telescope and other facilities, an international team of scientists has found the first gamma-ray binary in another galaxy and the most luminous one ever seen. The dual-star system, dubbed LMC P3, contains a massive star and a crushed stellar core that interact to produce a …
Multiple Star Systems - NASA Science
网页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. For example, our nearest stellar neighbor, the Alpha Centauri system, includes three stars.
