Physics

Scientific paper

COS will obtain ultraviolet spectra of a representative sample of brown dwarfs to study such questions as: {1} Is the hot gas in the outer atmospheres of young brown dwarfs heated by accretion? {2} Is the molecular hydrogen emission due to Lyman-alpha fluorescence or collisional excitation? {3} Are the older brown dwarfs without disks low mass analogs of active M dwarfs with flares and transient heating? {4} Are young brown dwarfs with disks low mass analogs of classical T Tauri stars?;
