What is a ' binary star system ' ?

Answer 1

A true binary star is a pair of stars in orbit around each other and bound together by thier mutual gravitational attraction.
They are also called double stars .
the classification of binaries includes those stars that appear to have nearby companions .

Answer 2

A binary star is a stellar system consisting of two stars orbiting around their center of mass. For each star, the other is its companion star. Recent research suggests that a large percentage of stars are part of systems with at least two stars. Binary star systems are very important in astrophysics, because observing their mutual orbits allows their mass to be determined. The masses of many single stars can then be determined by extrapolations made from the observation of binaries

binary star

A binary star is a stellar system consisting of two stars orbiting around their center of mass. For each star, the other is its companion star. Recent research suggests that a large percentage of stars are part of systems with at least two stars. Binary star systems are very important in astrophysics, because observing their mutual orbits allows their mass to be determined. The masses of many single stars can then be determined by extrapolations made from the observation of binaries.

Binary stars are not the same as optical double stars, which appear to be close together as seen from Earth, but may not be bound by gravity. Binary stars can either be distinguished optically (visual binaries) or by indirect techniques, such as spectroscopy. If binaries happen to orbit in a plane containing our line of sight, they will eclipse each other; these are called eclipsing binaries.

Systems consisting of more than two components, known as multiple stars, are also not uncommon and are generally classified under the same name. The components of binary star systems can exchange mass, bringing their evolution to stages that single stars cannot attain. Examples of binaries are Algol (an eclipsing binary), Sirius, and Cygnus X-1 (of which one member is probably a black hole).

Answer 4

The word "binary" means "two. A binary star system has two stars . . . usually one orbits the other, or in some instances, they orbit around each other. There are many binary star systems that can be seen with a good teloscope. The naked eye sees them as one star, but a good telescope has the ability to resolve them into their individual selves.

Answer 5

Binary means two so a binary star system is one composed of two stars orbiting each other. About half the stars in our galaxy are binary stars.

Answer 6

Our solar system would be a binary star system if we had two suns, some believe Jupiter used to be a star. Remember that shot in Star Wars when luke looks at the sky and sees to stars, they live in a binary star system.

Answer 7

A stellar system consisting of two stars orbiting about a common center of mass and often appearing as a single visual or telescopic object. Also called double star.

Answer 8

A star system which contains 2 stars. They may be in orbit around each other or one may orbit the other like a planet.
