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…
