The Diversity of Cold Worlds: Age and Characterization of the Exoplanet COCONUTS-2b
Rocio Kiman, Charles A. Beichman, Azul Ruiz Diaz +19
Studying cold brown dwarfs is key to understanding the diverse characteristics of cold giant exoplanets atmospheres. COCONUTS-2, is a wide binary system composed of a T9 brown dwar…
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…
JWST Coronagraphic Images of 14 Her c: a Cold Giant Planet in a Dynamically Hot, Multi-planet System
Daniella C. Bardalez Gagliuffi, William O. Balmer, Laurent Pueyo +16
Most observed multi-planet systems are coplanar, in a dynamically "cold" configuration of concentric orbits like our own Solar System. With the James Webb Space Telescope (JWST) we…
Diversity of Cold Worlds: A Near Complete Spectral Energy Distribution for 2MASS J04151954-0935066 using JWST
Sherelyn Alejandro Merchan, Jacqueline K. Faherty, Genaro Suárez +25
We present the a near complete spectral energy distribution (SED) for an extrasolar world: the T8 brown dwarf 2MASS~J041519540935066. Spanning from optical to mid-infrared (0.7-…
The Diversity of Cold Worlds: a blended-light binary straddling the T/Y transition in brown dwarfs
Daniella C. Bardalez Gagliuffi, Jacqueline K. Faherty, Genaro Suarez +22
We present the first brown dwarf spectral binary characterized with JWST: WISE J014656.66+423410.0, the coldest blended-light brown dwarf binary straddling the T/Y transition. We o…
