Black holes roz'yidaly first stars inside

Astronomers have found that the mechanism of first birth of black holes in the universe different from the mechanism of the birth of their modern brethren. Article scientists appeared in the journal Monthly Notices of the Royal Astronomical Society, and its summary is given in the press release, University of Colorado team, who participated in the work.

It is believed that black holes resulting from the gravitational collapse of stars in the final stage of its development. According to astronomers, the previous model does not take into account that the first stars many times exceeded the mass of existing lights, so the process of emergence holes in them differed.

According to investigators, billions of years ago, events were developing in the following manner. First, inside the star utvoryuvalasya black hole - embryo, which began to intensively absorb matter. This star joined the so-called phase kvazizirky - a black hole in the center and the stellar envelope outside. Then gas shell stars began to grow until it reached a size comparable to the size of the solar system.

Then utvoryuvalasya cloud of gas, which is located in the center of a black hole mass which could reach 10 thousand solar, which is many times more current stellar mass black holes.

According to researchers, the new scheme to explain how a young universe existed nadmasyvni black holes. Cchytayetsya that these objects are formed through the merger of smaller holes. In this case, because of the high-mass objects initial growth process nadmasyvnyh holes went very quickly.

More recently, another group of astrophysicists proposed an alternative theory nadmasyvnyh formation of black holes. Scientists believe that the first hole were normal size. They nahrivaly gas that surrounded them, which prevented the formation of stars (this process requires a relatively low temperature of matter). As a result, the universe appeared og romnyye gas clouds in which star formation has not happened. According to scientists, as a result of the collapse of these clouds and black holes formed nadmasyvni.
