The destruction of stars occurs for the different reasons, but not from ěčôč÷ĺńęîăî of exhaustion of nuclear fuel, as it is considered in a modern astrophysics.

First, this occurrence of conditions of nuclear explosion in íĺäđŕő of a star as a result of issue(emission) of neutrons by its(her) nucleus in atmosphere and enrichments by last by isotopes which are capable to enter in nuclear reaction (deuterium, ňđčňčé etc.). Such explosion refers to as as a "supernew" star. After him(it) there is a small rest(remainder) of the supercompressed matter named as a pulsar or " as a neutron star ", and cloud, scattered on a galaxy, of dust and gas.

Secondly, this collision of stars. Thus, if even one star is not the red giant, that is has the supercompressed nucleus, occurs âçđűâîîáđŕçíîĺ destruction of this nucleus to allocation of a plenty of energy of phase transition. Such event refers to as as a "new" star. Thus one smaller object from pair(vapour,couple) disappears only.

In third, this absorption of a star ęâŕçŕđîě.
