A new star that increases its brilliance hundreds or even thousands of times in a few hours, then gradually dims and returns to its original radiance after a few weeks. The presence of the nova is due to the presence of large-age stars that have almost completed the process of evolution. It appears in close binary systems when one of the components – a white dwarf or neutron star – is a degenerate star. When the evolutionary development of such systems occurs, the matter of the second component – a normal star – may begin to transfer to a neighboring star with signs of degradation. A thermonuclear explosion occurs on the surface of a white dwarf or in the magnetosphere of a neutron star, when a critical mass of matter accumulates there. It causes an explosion that destroys the shell of the star and increases its luminosity up to several thousand times. There have also been repeated outbreaks of new outbreaks.
