— In a movement of zone «D» from the border of zones «A» — «B» to the border of zones «B» — «C». In zone «B» the greater weights of gas are moving on a circle and deform a rising zone «D», mixing up with it. Under the action of powerful dynamic processes, «the accretion disk» is broken off, at the process of movement of zone «D», from zone «A» to zone «C», figure №R-8.5.

     (140)  Figure №R-8.5

  — Other possible variant: zone «D» rises to the border of zones «B» and «C», under the action of powerful dynamic processes directed to the center of «the accretion disk», zone «A» is being compressed and disappears, figure №R-8.6.

                                                                  (141)  Figure №R-8.6

The force of dynamic processes is concentrated in the center and being reflected to the opposite side and meets the shock waves directed to the center. At such movement of dynamic waves there are new centers of thermonuclear synthesis which strengthen the dynamic processes in «the accretion disk» and break it off.

It is probable, that for the break of «the accretion disk», there is enough force of the reflected shock waves. The capacity of shock waves and the dynamic processes depends on the weight collected in «the accretion disk».

Different variants of the events succession, depending on the weight collected in «the accretion disk» are possible.

               Variant 2

  Thermonuclear synthesis (zone «D») begins at the borders of zones «B» — «C», figure №R-8.7. 

                                                                      (142)  Figure №R-8.7

Under the action of the dynamic processes directed to the center of «the accretion disk», the zone «A» will probably disappear. The shock waves born in zone «D» are focused and collide in the center of «the accretion disk», and they should be reflected to the opposite side, figure №R-8.8a.

At the returning, the reflected shock wave should meet a shock wave going from zone «D» to the center. In the place of this meeting of shock waves, a formation of thermonuclear synthesis zones, zone «E», is possible figure №R-8.8b.

                                                      (143) Figure №R-8.8

In case when «a black hole» and its «accretion disk» aren’t of greater sizes, there is a birth of one star.

  If «the black hole» and its «accretion disk» are commensurable with the sizes of a galaxy, there is a birth of more than one star. Such birth of stars, probably, occurs under the following scheme: very powerful shock wave directed from zone «D», to zone «A», focused on the center, breaks off all the collected weight and throws out this weight packed into stars, in different directions, figure №R-8.9.

                                                                  (144)  Figure №R-8.9

Probably, the break and the emission of weights occur after the meeting of shock waves directed from zone «D» to the center and the reflected waves. In this case, the capacity of the action of forces directed on the break should increase due to the occurrence of zones «E», in the place of meeting of shock waves and the occurrence of thermonuclear synthesis. In places of shock waves passage, since it aimed to the center, and back, occurrence of zones of thermonuclear synthesis is probable, figure №R-8.10.
