It really goes case by case. Some single stars are so massive and large that its very easy to determine its mass. Same goes for single stars of far less mass in our neck of the woods in our galaxy(within 300 light years) While determining the mass of multiple star systems get tricky, while its easy to determine the mass of nearby binary star systems such as Alpha Centauri system and the Cappella System. but sometimes its very tricky when the primary star in a system is many times larger then their counterparts. for example we know that Polaris (North Star) has 2 smaller companions and we even have rough estimates of their orbits. but since Polaris A is so large and massive its hard to tell the mass of its smaller compatriots.

How many stars make up binary star?
By definition, a binary star system has two stars in it.
To calculate the mass of a star scientists study?
the orbits of binary stars
What is the difference between a single-line and a double-line spectroscopic binary?
A single-line spectroscopic binary contains two stars, but only one star's spectrum is visible due to the other being too faint or obscured. In contrast, a double-line spectroscopic binary allows for the detection of both stars' spectra, as both are bright enough to be observed. This distinction helps astronomers determine orbital parameters and mass ratios of the stars in the system.
Are all binary stars part of star systems explain?
Yes, all binary stars are part of star systems. Binary stars are pairs of stars that orbit around a common center of mass due to their gravitational attraction to each other. While they may be the only two stars in their system, they are still considered part of a larger system.
How can stellar masses be determined by observing binary star systems?
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.
Are all stars single?
Current observation suggest that about 50% of all star systems are binary stars.
Why are binary stars common?
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.
Stars that are found in pairs are called?
Two stars orbiting each other are "binary stars" ...a group of stars near each other, may be formally or informally known as a "cluster".
What colors are binary stars?
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.
What percent of stars in the sky that appear to be stars are actually binary stars?
From Wikipedia, article binary star: "It is estimated that approximately 1/3 of the star systems in the Milky Way are binary or multiple, with the remaining 2/3 consisting of single stars."It should be emphasized that this is just an estimate - some double or multiple stars are hard to detect.
What are the names of the 2 famous stars that revolve around each other?
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.
Why are most visual binary stars of low luminosity?
Most visual binary stars are of low luminosity because they are often close together and both stars have similar masses, resulting in them being fainter than single stars of the same age. Additionally, the companion stars in these binary systems may not be large or hot enough to emit high levels of light.
What percentage of stars are binary stars?
Roughly half of all stars in the galaxy are estimated to be part of binary or multiple star systems. This means approximately 50% of stars are binary stars.
What are two stars bound by gravity called?
Binary stars
Parallax would be easier to measure if?
Parallax would be easier to measure if the Earth were farther from the sun. This way, there will be a wider angle to the stars using the parallax method.
How many stars make up binary star?
By definition, a binary star system has two stars in it.
How is a binary used?
Binary what? Binary numbers? Binary stars? Binary fission?
