JWST COMPASS: Insights into the Systematic Noise Properties of NIRSpec/G395H From a Uniform Reanalysis of Seven Transmission Spectra

Tyler A. Gordon, Natalie M. Batalha, Natasha E. Batalha +9

JWST has already observed near-infrared transmission spectra of over a dozen super-Earths and sub-Neptunes. While some observations have allowed astronomers to characterize sub-Nep…

Escaping Helium and a Highly Muted Spectrum Suggest a Metal-Enriched Atmosphere on Sub-Neptune GJ3090b from JWST Transit Spectroscopy

Eva-Maria Ahrer, Michael Radica, Caroline Piaulet-Ghorayeb +27

Sub-Neptunes, the most common planet type, remain poorly understood. Their atmospheres are expected to be diverse, but their compositions are challenging to determine, even with JW…

JWST COMPASS: NIRSpec/G395H Transmission Observations of TOI-776 c, a 2 Rearth M Dwarf Planet

Johanna Teske, Natasha E. Batalha, Nicole L. Wallack +16

The atmospheres of planets between the size of Earth and Neptune at short orbital periods have been under intense scrutiny. Of the ~dozen planets in this regime with atmospheres st…

JWST COMPASS: NIRSpec/G395H Transmission Observations of the Super-Earth TOI-776b

Lili Alderson, Sarah E. Moran, Nicole L. Wallack +15

We present two transit observations of the 520K, 1.85R, 4.0M super-Earth TOI-776b with JWST NIRSpec/G395H, resulting in a 2.8-5.2m transmission spectrum.…

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…
