Brown-Dwarf planets question

[Puke]

just found this, i was only mostly wrong:

Brown dwarfs are failed stars somewhere in mass between a large planet and a small star. This makes them large enough to collapse and heat up, but not big enough to ignite the steady nuclear fires necessary to keep stars burning for billions of years. Instead, after a brief hot flash, brown dwarfs cool off until they become dead cinders.

They are extremely dim and went undetected until the recent construction of larger, more sensitive telescopes. Basri confirmed the first lithium brown dwarf in 1995 using Hawaii's Keck I Telescope, and since then several dozen have been found in nearby clusters or floating freely in the solar neighborhood.

The brown dwarf known as LP 944-20 is one of the nearest, only 16 light years from Earth. In fact, it was first detected more than 25 years ago but was thought to be a very dim red star called a red dwarf. The recent observation of lithium in its atmosphere marks it as a brown dwarf.

LP 944-20, located in the constellation Fornax in the southern skies, is about 500 million years old and has a mass that is at most 60 times that of Jupiter, or six percent of the sun's mass. Its diameter is about one-tenth that of the sun, and it has a rotation period of less than five hours.

Very young brown dwarfs are observed to have coronae, Basri said. They are hot enough to have sufficiently ionized atmospheres that can tangle with their magnetic fields. As they get entangled, the magnetic fields twist and occasionally cross, arcing like an electrical short and creating a flare.

These flares are thought to inject high energy particles into the upper atmosphere or corona, producing temperatures up to several million degrees Celsius.

As the dwarfs cool, however, the atmosphere should cool and the gases de-ionize into a neutral gas. Magnetic fields do not interact with a neutral atmosphere, and thus atmospheric activity dies down and the corona disappears.

by the way, always good to see you on the forum, Daynarr. any hint on what you are working on?
