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.

### What is the double dark theory?

"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 the 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."

### The mass of a star can be determined by studying?

### Where in the world uses the binary systems?

Everywhere. All computers use binary systems.

### How are contact binaries different than binary systems?

A binary system is a stellar system which has two stars orbiting each other (actually their combined centre of mass). When their gravitational attraction pulls them together so that their masses begin to merge, they become contact binaries.

### Which property of a star can be determined from binary star system?

Binary stars are ideal to determine the mass of the components.

### Why all of the observed stellar -remmant black-hole candidates members of close binary systems?

Those are easier to observe than an isolated black hole, because the black holes are usually discovered because of infalling matter that emits X-rays, or because other objects move around an invisible object (the black hole).

### How many black holes make one binary system?

well you wouldn't need any to make a black holes to make binary systems but what do make binary systems are two stars.

### How do you know if compound is binary or ternary?

This is determined by chemical analysis.

### Do open source operating systems use binary code as a base like WindowsTM?

All operating systems have to use binary code in order to operate. The difference between open-source operating systems and Windows is that you can see the code before it is converted into a binary format.
