Maunakea, Hawaii, February 7, 2025: Astronomers using the Keck Planet Imager and Characterizer (KPIC) have obtained high-resolution spectral data of brown dwarf HD 206893 B, uncovering new details about its atmosphere and formation. Located in a circumstellar debris disk, this substellar object is in the L/T transition phase, with complex cloud structures and atmospheric variations.
Spectroscopic analysis detected molecular absorption lines, refining estimates of temperature, surface gravity, and orbital dynamics. These findings enhance understanding of directly imaged exoplanets and brown dwarfs, contributing valuable insights into their formation and evolution.
