Binary stars can be any color that stars can be. There's no need for the two stars in a binary to be the same color.
No, in fact they are quite common. Many stars that, with the naked eye, look like a single star, are actually double or multiple stars.
All serious astronomers realize that there are binary stars.
The stars are said to be a "gravitational binary pair"
Not exactly, while a pulsar is a specific type of neutron star (that being a "spinning neutron star") and a binary system is a pair of stars orbiting each other, a pulsar does not need to be part of a binary system. It would be possible, however to have a binary system with one of the pair being a pulsar and the other a neutron star (assumed to be the non-spinning or "normal neutron star" variety).
The nearest ones to us are:Sirius- BinaryArcturus - Possible binaryAlpha Centauri ARigel - BinaryProcyon - BinaryAchernar - BinaryAnswer:Alpha Centuri is not a binary star system as it contains three stars, not two. Proximia Centuri aka Alpha Centuri C is the closest star to us. Alpha Centuri A and Alpha Centuri B are the other two stars.
Two stars orbiting each other are "binary stars" ...a group of stars near each other, may be formally or informally known as a "cluster".
Binary stars
Yes all binary stars are part of the star system because all galaxies and universes have stars and you have to have at least two stars for it to be binary stars.
Binary what? Binary numbers? Binary stars? Binary fission?
About 50% of all stars are binary stars - they all have different temperatures.
the orbits of binary stars
55%
Binary stars are very useful for determining the mass of the stars and thus any objects orbiting around them.
"Binary" means there are two stars. And "protostar" means the stars are in an early, or preliminary, stage.
By definition, a binary star system has two stars in it.
There are lots of binary stars. Doing a search on "binary stars" should get you several. It seems that binary (or multiple) stars are about as common as single stars; at least, they are in the same order of magnitude.
binary stars are two stars that orbit each other while supernovas and novas stars are stars that explode when it runs out of fuel
