Binary stars are ideal to determine the mass of the components.
The mass of a binary star(s) can be directly determined from its gravitational attraction.
Single stars cannot be directly determined.
Luminosity
Stellar masses can be determined by observing binary star-systems. The calculations of the orbits of the binary stars allow the masses of their component stars to be directly determined, which in turn allows other stellar parameters, such as radius and density, to be indirectly estimated.

By definition, a binary star system has two stars in it.

Star system with 2 star called? binary star system
binary star systems
Yes. No, it is called a binary system.
A binary star is not any particular color. A binary star system can contain stars of any spectral type.
Stellar masses can be determined by observing binary star-systems. The calculations of the orbits of the binary stars allow the masses of their component stars to be directly determined, which in turn allows other stellar parameters, such as radius and density, to be indirectly estimated.
A binary star is simply a system containing two stars, which does not say anything about the system's mass.
No - it is a single star system
A binary star system is two stars that orbit around each other
