The Sonora Substellar Atmosphere Models VI. Red Diamondback: Extending Diamondback with SPHINX for Brown Dwarf Early Evolution

C. Evan Davis, Jonathan J. Fortney, Aishwarya Iyer +5

We extend the Sonora Diamondback brown dwarf evolution models to higher effective temperatures to treat the evolution of younger, higher mass objects. Due to an upper temperature l…

HET/HPF observations of Helium in warm, hot, and ultra-hot Jupiters

Jaume Orell-Miquel, Kyra Sampson, Caroline V. Morley +5

The near-infrared helium triplet line is a powerful tool for studying atmospheric escape processes of close-in exoplanets, especially irradiated gas giants. Line profile fitting pr…

Silicate clouds and a circumplanetary disk in the YSES-1 exoplanet system

Kielan K. W. Hoch, Melanie Rowland, Simon Petrus +26

Young exoplanets provide a critical link between understanding planet formation and atmospheric evolution. Direct imaging spectroscopy allows us to infer the properties of young, w…

The Sonora Substellar Atmosphere Models. V: A Correction to the Disequilibrium Abundance of CO for Sonora Elf Owl

Nicholas F. Wogan, James Mang, Natasha E. Batalha +6

To aid the interpretation of observations of substellar atmospheres, Mukherjee et al. (2024) created the Sonora Elf Owl grid of model atmospheres, simulations that accounted for di…

Thermal Emission and Confirmation of the Frigid White Dwarf Exoplanet WD 1856+534b

Mary Anne Limbach, Andrew Vanderburg, Ryan J. MacDonald +12

We report the detection of thermal emission from and confirm the planetary nature of WD 1856+534b, the first transiting planet known to orbit a white dwarf star. Observations with…

A temperate super-Jupiter imaged with JWST in the mid-infrared

E. C. Matthews, A. L. Carter, P. Pathak +16

Of the ~25 directly imaged planets to date, all are younger than 500Myr and all but 6 are younger than 100Myr. Eps Ind A (HD209100, HIP108870) is a K5V star of roughly solar age (r…
