Binary Star Systems
As is our brother / sister, so in our universe most of the brothers have sisters. In our solar system in which our sun is alone, in reality it is a coincidence coincidence. They have twins with most stars. In the 16th article of 'Basic Basics of Astrophysics' series, we will discuss in detail about Combination Tara System.

What is a pair of stars?
Combination star system is the star system in which two stars are bound to gravitationally by one another. In such a star system, either a star orbiting another star, or both stars revolve around a gravitational center in between the two of them. Most stars in the universe are in the pair system. In these stars, the darkest star is called the primary star (A) while the second lesser star is called the secondary star (B). If the two stars have the same lamp, those who find them, provide them primary and secondary status. According to an estimate, 85% of the star stars in the stars in our night sky are twin stars. Some of these three star systems and some systems have more stars than this.
Classification of Combination Star System
Combination star systems are basically classified as either remote or near pair pairs. As if by name itself it is clear that in the remote pair of stars, their orbit keeps each other at a distance. In their lifetime, these stars have little or no effect on each other. In contrast to the pairs of proximate stars, these stars are so close that they react physically to each other. In this, gravity of a star distorts or feeds another star. In some cases, the substance of a star is grabbed by another star.
In addition to this basic classification, the pair system is also classified on the type of their exploration.
Visual Binaries
There is so much distance between visible pair stars that they can be seen separately from any binoculars. From their long-term inspection, the members can be documented in relative positions of the stars and their inspection can be calculated by this inspection. For us, 5 to 10% of visible stars have visual pair stars.
Spectroscopic binaries
Although spectroscopy is seen in a pair of telescope with telescope, they are also very close, they can not be seen separately. Their spectrum lines are studied for independent inspection and study of these stars. Most couples have been searched with Dappler deviation in their spectrum lines. If the pair has not been identified separately then its spectrum will be a mixture of spectrum of member strings of that star system. With the time of these spectral lines, the study gets information about the orbital speed of its member wires. Many other factors are also taken care of for the spectroscopy study of the pair of stars.
Eclipsing Binaries
In this star system the stars revolve each other with an angle that when we inspect them from the Earth, they pass through each other in front of them. This is an eclipse taken by a star on another star. This method combines the pair of stars with the orbit of those stars from the earth on a line, and that star is not dependent on the effect of any property of the system.
Astrometric Binaries
If there are frequent inspections of some stars, their speed changes with noticeable changes over time. If this change is predominant, then we assume that this motion in its motion is the effect of the gravity of the unknown companion star. In simple words, a star appears dancing around an empty space in which its companion star inspection is ineptly blurred. Only a few stars have been discovered by astrophysicical combinations, because this method requires long periods of inspection and there is a possibility of more uncertainty in measuring their status and speed.
Joint Star Systems
Combination stars provide the best method for calculating the mass of a remote star. The gravitational attraction between these fellow stars forces them to revolve around their middle center. The mass of those stars can also be calculated by deviation in the spectrum of spectroscopy or spectroscopy of the visual pair stars. With the help of these figures, it is possible to study the connection between the star and the mass of that star.

This study can be estimated by the mass of stars alone. Some pairs of strings have provided a good laboratory for the study of general relativism and gravitational waves. Combination stars also have the possibility of creating the necessary conditions for the development of life.
