The SPHINX M dwarf Spectral Grid. II. New Model Atmospheres and Spectra to Derive Fundamental Properties of mid-to-late type M-dwarfs

Aishwarya R. Iyer, Michael R. Line, Philip S. Muirhead +2

M-dwarfs are the most dominant stars in the Galaxy. Their interiors and atmospheres exhibit complex processes including dust condensation, convective feedback, and magnetic activit…

The JWST weather report from the nearest brown dwarfs III: Heterogeneous clouds and Thermochemical instabilities as possible drivers of WISE 1049AB's spectroscopic variability

Natalia Oliveros-Gomez, Elena Manjavacas, Theodora Karalidi +17

We present a new analysis of the spectroscopic variability of WISE~J104915.57531906.1AB (WISE~1049AB, L7.5+T0.5), observed using the NIRSpec instrument onboard the James Webb Sp…

Sensitivity to Sub-Io-sized Exosatellite Transits in the MIRI LRS Lightcurve of the Nearest Substellar Worlds

Andrew Householder, Mary Anne Limbach, Beth Biller +20

JWST's unprecedented sensitivity enables precise spectrophotometric monitoring of substellar worlds, revealing atmospheric variability driven by mechanisms operating across differe…

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…

X-SHYNE: X-Shooter spectra of young exoplanet analogs II. Presentation and analysis of the full library

Simon Petrus, Gaël Chauvin, Mickaël Bonnefoy +29

The X-SHYNE library is a homogeneous sample of 43 medium-resolution (R=8000) infrared (0.3-2.5um) spectra of young (<500Myr), low-mass (<20Mjup), and cold (Teff=600-2000K) isolated…

The JWST Weather Report: retrieving temperature variations, auroral heating, and static cloud coverage on SIMP-0136

Evert Nasedkin, Merle Schrader, Johanna M. Vos +15

SIMP-0136 is a T2.5 brown dwarf whose young age (~Myr) and low mass (~M) make it an ideal analogue for the directly imaged exoplanet population. With…

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…

The JWST weather report from the nearest brown dwarfs II: Consistent variability mechanisms over 7 months revealed by 1-14 m NIRSpec + MIRI monitoring of WISE 1049AB

Xueqing Chen, Beth A. Biller, Xianyu Tan +22

We present a new epoch of JWST spectroscopic variability monitoring of the benchmark binary brown dwarf WISE 1049AB, the closest, brightest brown dwarfs known. Our 8-hour MIRI low…
