A search for late-type brown dwarfs in the Euclid Quick Data Release 1

Frank Kiwy, J. Davy Kirkpatrick, Adam C. Schneider +9

We present the identification and characterization of 15 mid-to-late T dwarf candidates in the Euclid Quick Release 1 (Q1) dataset, based on a combined photometric and spectroscopi…

Observation of undepleted phosphine in the atmosphere of a low-temperature brown dwarf

Adam J. Burgasser, Eileen C. Gonzales, Samuel A. Beiler +16

The atmospheres of low-temperature brown dwarfs and gas giant planets are expected to contain the phosphine molecule, PH However, previous observations have shown much lower ab…

Diversity of Cold Worlds: Predicted Near- to Mid-infrared Spectral Signatures of a Cold Brown Dwarf with Potential Auroral Heating

Genaro Suárez, Jacqueline K. Faherty, Ben Burningham +12

Recent JWST/NIRSpec observations have revealed strong methane emission at 3.326 microns in the 482 K brown dwarf CWISEP J193518.59154620.3 (W1935). Atmospheric modeling…

Lyman-Alpha Emission from K and M Dwarfs: Intrinsic Profiles, Variability, and Flux in the Habitable Zone

Sarah Peacock, Travis S. Barman, R. O. Parke Loyd +4

Lyman- (Ly) is the most prominent ultraviolet emission line in low-mass stars, playing a crucial role in exoplanet atmospheric photochemistry, heating, and escape. However, i…

Discovery of the Second Y+Y Dwarf Binary System: CWISEP J193518.59-154620.3

Matthew De Furio, Jacqueline Kelly Faherty, Daniella C. Bardalez Gagliuffi +10

We present the discovery of a companion to the Y-dwarf, CWISEP J193518.59-154620.3, the second Y-Y dwarf binary detected to date. Y-dwarfs are the coldest known free-floating objec…
