Researchers discovered two irradiation sources comparable in size with the Sun

Using astronomical observatory «Radioatron» and ground-based radiotelescopes located in several countries, Russian researchers have managed to discover two sources of maser radiation, with each of these two sources having sizes comparable with a diameter of the Sun. This finding has been reported by the press-office of Ural Federal University (UrFU), which is a member of the project.

An international team of «Radioaston» has investigated an area of active star formation Ser A located in about 2 thousand light-years from the Earth. As a result, they have managed to distinguish in this object two ultra-compact bright spots of maser radiation, while each spot is comparable with the diameter of the Sun.

Maser is an analog of the laser, emitting not visible light, but radiowaves. «Most probably, we observe an interaction of a gas jet going out of a neighbor star with a hindrance. In a gas of such jet, turbulent events take place. In vortices appearing most closely to the hindrance, we observe ultra-compact maser details,» - a coauthor of the article, leading research assistant of Kourovskaya astronomic observatory of UrFU Andrei Sobolev commented.
