JWST COMPASS Program: The 3--5m transmission spectrum of LTT 1445 A b
Natasha E. Batalha, Nicole Wallack, Tyler Gordon +16
The search for an atmosphere on the closest rocky M dwarf planet, LTT 1445 A b, has been the subject of intense investigation from both the ground and space. Here, we present the f…
High Tide or Riptide on the Cosmic Shoreline? A Water-Rich Atmosphere or Stellar Contamination for the Warm Super-Earth GJ~486b from JWST Observations
Sarah E. Moran, Kevin B. Stevenson, David K. Sing +21
Planets orbiting M-dwarf stars are prime targets in the search for rocky exoplanet atmospheres. The small size of M dwarfs renders their planets exceptional targets for transmissio…
Additional JWST/NIRSpec Transits of the Rocky M Dwarf Exoplanet GJ 1132 b Reveal a Featureless Spectrum
Katherine A. Bennett, Ryan J. MacDonald, Sarah Peacock +17
As an archetypal M-dwarf rocky exoplanet, GJ 1132 b has a varied history of atmospheric measurements. At 1.13 , 1.66 , and 580 K, it orbits a bright…
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 HUSTLE Program: The UV to Near-IR Transmission Spectrum of the Hot Jupiter KELT-7b
Carlos Gascón, Mercedes López-Morales, Ryan J. MacDonald +14
The ultraviolet and optical wavelength ranges have proven to be a key addition to infrared observations of exoplanet atmospheres, as they offer unique insights into the properties…
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…
