while looking for brown dwarfs or â##failed stars. â#PSO J318. 5-22â#s ultrared color stood apart from the other objects in the survey astronomers said.
but from a low-mass star at the boundary between stars and brown dwarfs. The discovery reveals a major difference between the magnetic activity of more-massive stars and that of brown dwarfs and planets,
the scientists said. ll the magnetic activity we see on this object can be explained by powerful auroras,
his indicates that auroral activity replaces solar-like coronal activity on brown dwarfs and smaller objects,
Brown dwarfs, sometimes called ailed stars, are objects more massive than planets, yet too small to trigger the thermonuclear reactions at their cores that power stars.
and brown dwarfs have outer atmospheres that support auroral activity, rather than the type of magnetic activity seen on more-massive and hotter stars.
#First Direct evidence of the Formation Process of Brown dwarfs Using the Very Large Array, an international team of astronomers has discovered jets of material ejected by still-forming young brown dwarfs,
revealing the first direct evidence that brown dwarfs are produced by a scaled-down version of the same process that produces stars.
The astronomers studied a sample of still-forming brown dwarfs in a star-forming region some 450 light-years from Earth in the constellation Taurus,
and found that four of them have the type of jets emitted by more-massive stars during their formation.
The scientists also observed the brown dwarfs with the Spitzer and Herschel space telescopes to confirm their status as very young objects. his is the first time that such jets have been found coming from brown dwarfs at such an early stage of their formation,
and shows that they form in a way similar to that of stars, said Oscar Morata, of the Institute of Astronomy and Astrophysics of the Academia Sinica in Taiwan. hese are the lowest-mass objects that seem to form the same way as stars,
Brown dwarfs are less massive than stars, but more massive than giant planets such as Jupiter. They have insufficient mass to produce the temperatures
whether brown dwarfs form like stars or like planets. Stars form when a giant cloud of gas
Previous evidence strongly suggested that brown dwarfs shared the same formation mechanism as their larger siblings
Based on this discovery, e conclude that the formation of brown dwarfs is scaled a-down version of the process that forms larger stars,
