Uniform Forward-Modeling Analysis of Ultracool Dwarfs. IV. Benchmarking the Sonora Diamondback and Saumon & Marley (2008) Atmospheric Models Across Late-M, L, and T types with Low-Resolution 0.8-2.5 m Spectroscopy
Emily Mader, Zhoujian Zhang, Jonathan J. Fortney +6
(Abridged) We present a systematic assessment of two major cloudy atmospheric model grids -- SM08 (Saumon & Marley 2008) and Sonora Diamondback -- when applied to low-resolution ne…
The OATMEAL Survey. II. The 3D spin-orbit obliquity of an eccentric transiting brown dwarf in the Ruprecht 147 open cluster
Theron W. Carmichael, Steven Giacalone, Noah Vowell +11
We present new analysis of the CWW 89 system as part of the Orbital Architectures of Transiting Massive Exoplanets And Low-mass stars (OATMEAL) survey. The CWW 89 system is a membe…
A Pair of Dynamically Interacting Sub-Neptunes Around TOI-6054
Maxwell A. Kroft, Thomas G. Beatty, Ian J. M. Crossfield +31
We confirm the planetary nature of a pair of transiting sub-Neptune exoplanets orbiting the bright F-type sub-giant star TOI-6054 (, ) as a part of the OrCAS radia…
OrCAS: Origins, Compositions, and Atmospheres of Sub-neptunes. I. Survey Definition
Ian J. M. Crossfield, Alex S. Polanski, Paul Robertson +61
Sub-Neptunes - volatile-rich exoplanets smaller than Neptune - are intrinsically the most common type of planet known. However, the formation and nature of these objects, as well a…
