Brown Dwarfs Could Reveal Secrets of Planet and Star Formation

The standard mechanism for star birth is through the gravitational collapse of a cold interstellar cloud of gas and dust. As the cloud contracts it heats due to the Kelvin–Helmholtz mechanism. Early in the process the contracting gas quickly radiates away much of the energy, allowing the collapse to continue. Eventually, the central region becomes sufficiently dense to trap radiation. Consequently, … Web2 de ago. de 2013 · Brown dwarfs are an odd set of objects that are neither planets nor stars.
