Astronomers of Ibaraki University in Japan have recorded a rare event accretion of the explosion, the source of which became supermassive protostar G358-MM1. This publication reports Science Alert.

Accretion the explosion usually occurs with the formation of a star when the latter absorbs from the interstellar medium too much substance. Such outbreaks have been observed in the milky Way only three times. It is well known that become active natural masers — radio-wave equivalent of lasers, which are observed at centimeter wavelengths.

In 2019, scientists using the Australian antenna array with long bases (Australian Long Baseline Array) recorded increased activity of the masers associated with the protostar G358-MM1. Subsequent observations revealed the heat coming from the source through the matter surrounding the star. A similar phenomenon was observed for the first time and was not observed in two previously discovered accretion explosions.

According to scientists, they recorded a previously unknown type of the accretion burst. It is possible that there are a number of varieties of these phenomena, whose properties depend on the mass and evolutionary stage of the young star.
