How are brown dwarfs like jovian planets

Web5 de set. de 2024 · Brown dwarfs fall somewhere between the masses of giant planets like Saturn and Jupiter, and the smallest stars. 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, …
