Stellar Mass Black Hole Analysis

When a star runs out its star's fuel supply, it will collapse under its own gravity. Depending on the quality, the stars eventually become white dwarfs or more compact neurons. When the stellar mass exceeds Tolman-Oppenheimer-Volkof limit of about 5 to 0 M (Bombaci 1996), a stable neutron star can not be obtained and continues to collapse, and when reaching r black hole (BH) 2 GM / c 2 is formed . Where G is the gravitational constant, M is the mass of the object, and c is the speed of light.

In black hole astrophysics, we know the "stellar mass" black hole - basically 5 to 100 solar mass black holes are left behind a massive supernova. Millions to millions (and even billions) solar mass. You may have noticed a big quality gap between these two types of black holes. When the black hole begins to shrink and grows with time, what kind of black hole bridges the stellar mass black hole and the super monsters?

In general, the most common black holes in the modern universe fall into two broad categories. Stellar mass black hole and super mass black hole. You thought that a stellar mass black hole was formed after a huge star exploded into a supernova. A massive black hole "heavier" among millions to billions of sun masses is a monster living in the center of the Galaxy. (There are many studies to understand how black holes evolve from stars to super masses There are several ways to solve this problem, but "middle quality" black holes are "missing links" It may be.

Astronomers are looking for a "medium quality" black hole (IMBH) to fill this gap and have to know a lot of IMBH, as they know the advantages of stellar masses and super mass black holes. However, there are only a few candidates. This is a very strange thing. If the theory of black hole evolution is correct, it is not too difficult to track the middle black hole that falls within the mass range of 100 million to 1 million solar masses. Are these emissions hard to find for us? Or is the lack of observational evidence a clue to their scarcity?
