Astronomers zahlyanuly childhood in brown dwarfs
Astronomers were able to detect brown dwarfs in the early stages of their development. Article scientists appeared in the journal Astronomy and Astrophysics, and its summary is given in the press release at the Jet Propulsion Laboratory (Jet Propulsion Laboratory - JPL).
Brown dwarf - a failed star, that is, objects weighing more than 75-80 yupiterianskyh, but not enough to support thermonuclear reactions inside the object, specific to the stars. So far, among the astronomers were not unanimous about how these objects appear - as a star or a planet.
Within the new work of scientists interested in young brown dwarfs. To find them requested to use the space telescope Spitzer. With this apparatus astrophysicists observed object Sstb213 J041757. As a result they were able to establish that he is two brown dwarf surrounded by dense clouds of dust.
According issledovat unction, new results show that dwarfs formed as stars. In particular, changes in the distribution of electromagnetic energy on frequencies which are observed in these objects, like a picture, typical for low-mass stars. Scientists note that the detection of the object at this early stage of development - a great success. The fact that dwarfs evolving very quickly measure the space, so to see their "childhood" is extremely daunting task.
Brown dwarfs are very interesting objects for study. So recently, astronomers have found in these objects weather. In particular, dwarf atmosphere were dust clouds.
