W75N(B)-VLA2

W75N (B) -VLA2, also known as VLA2 or Very Large Array 2, is a protester in the star cluster W75N (B), which is 4200 light years away from Earth. The formation of heavier stars than the sun can be observed on this relatively close object.

He is named after the Radiotelcope Very Large Array, with which he was observed. The formation of massive stars can be observed on the protostern, which is less well-known than the formation of sun-like stars. They develop considerably faster (here the star has eightfold solar mass, is 300 times brighter than the sun and is created within 100,000 years); however, it is unclear whether the development is similar to that of light stars (typically dust-accretion disk around the star in which the planets are formed, with two gas jets perpendicular to it), or whether several protosters collide to produce heavy stars. The VLA has made recordings of 20 years (1996, 2014) (conducted by the Mexican astronomer Carlos Carrasco-González, participation, among others, Huib van Langevelde from Leiden) and the observations supported the hypothesis that they are similar to light stars. An originally isotropic gas cloud became more elliptical. This is confirmed by observations of the natural astronomical maser (water and methanol) in this system, which testify to high magnetic fields consistent with a jet mechanism. There are also two other radio sources in the star cluster (VLA 1 is older, VLA 3 younger than VLA 2). Weblinks Edit sourcetext Single-level Edit source text
