JWST COMPASS: NIRSpec/G395H Transmission Observations of the Sub-Neptune HD 15337 c
Nicole L. Wallack, Peter Gao, Michael Greklek-McKeon +17
We present the 3-5 m transmission spectrum of HD 15337 c (TOI-402.02), a sub-Neptune (2.526 R, 6.792 M, T656 K) around a K1V star observe…
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…
THYME XIII: Two young Neptunes orbiting a 75-Myr star in the Alpha Persei Cluster
Anne Dattilo, Andrew M. Vanderburg, Madyson G. Barber +28
Young planets with mass measurements are particularly valuable in studying atmospheric mass-loss processes, but these planets are rare and their masses difficult to measure due to…
JWST COMPASS: A NIRSpec G395H Transmission Spectrum of the Super-Earth GJ 357 b
Jea Adams Redai, Nicholas Wogan, Nicole L. Wallack +14
We present JWST NIRSpec/G395H transmission spectroscopy observations of GJ 357 b, a warm ( K) super-Earth (, $1.84\ \mathrm{…
The Spin Zone: Synchronously and Asynchronously Rotating Exoplanets Have Spectral Differences in Transmission
Nicholas Scarsdale, C. E. Harman, Thomas J. Fauchez
New observational facilities are beginning to enable insights into the three-dimensional (3D) nature of exoplanets. Transmission spectroscopy is the most widely used method for cha…
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…
