Scientists call the “new” those stars, the luminosity of which suddenly increases ten thousand times.
Such a star and was SMCN 2016-10a, located in the galaxy called the Small Magellanic cloud. Due to increments of the mass of the star by the gravitational attraction of matter, so-called process of accretion, the scientists noted an unusual brightness of the star.
SMCN 2016-10a is a white dwarf and source energy is the companion star. When “the star-recipient” experiencing uncontrolled fusion reaction due to reaching critical density, there is an increase in brightness.
At the moment a new star is recognized as one of the brightest in the known Universe and the brightest star in the galaxy, which is 200 thousand light-years from the milky way and is one of the nearest to him.
