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 observed…

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 High-Resolution Non-Detection of Escaping Helium In The Ultra-Hot Neptune LTT 9779b: Evidence for Weakened Evaporation

Shreyas Vissapragada, Patrick McCreery, Leonardo A. Dos Santos +16

The recent discovery of ``ultra-hot'' ( day) Neptunes has come as a surprise: some of these planets have managed to retain gaseous envelopes despite being close enough to th…

The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems II: A 1 to 20 Micron Spectrum of the Planetary-Mass Companion VHS 1256-1257 b

Brittany E. Miles, Beth A. Biller, Polychronis Patapis +101

We present the highest fidelity spectrum to date of a planetary-mass object. VHS 1256 b is a 20 M widely separated (8\arcsec, a = 150 au), young, planetary-…
