Webb Telescope’s Startling Find: Auroral Phenomenon on a Starless Brown Dwarf

The team hypothesizes that the methane emission may be due to procedures producing aurorae.These findings are being presented at the 243rd conference of the American Astronomical Society in New Orleans.To help describe the mystery of the infrared emission from methane, the group turned to our solar system. For separated brown dwarfs like W1935, the lack of a stellar wind to contribute to the auroral procedure and describe the additional energy in the upper atmosphere needed for the methane emission is a mystery.”We anticipated to see methane due to the fact that methane is all over these brown overshadows. Searches were carried out with ground-based telescopes like the Keck Observatory for infrared signatures from these radio-emitting brown overshadows to further define the phenomenon however were inconclusive.W1935 is the very first auroral candidate outside the solar system with the signature of methane emission.
