The stars.

The Stars - are the shining (plasma) spheres like the Sun. Generated from the gas and dust medium due to the gravitational instability. The star’s masses M are from 0,04 to 60 л¤, luminary (L) from 0,5 to hundreds thousand L¤ (see later). The stars are classified by their luminance mass, the surface temperature, chemical composition, the spectrum peculiarities. On the definite step of the stars evolution the stars come through the period of nonstationarity (see "nonstationary stars"). Depending on mass the stars become at the end of evolution the white dwarfs or the neutron stars or the black holes.

Rigel

The blowing stars.

The supernew stars.

Supernew star are unexpectedly bursting star, the power of which during the burst is from 10^40 erg/s and higher. The gravitational collapse brings these bursts.

The doublestars.
