Recent ground- and space-based surveys have shown that planets between Earth and Neptune in size, known as “super-Earths,” are among the most frequently found planets in the Galaxy.

No Thick Atmosphere On The Terrestrial Exoplanet Gl 486b
A primary science goal for JWST is to detect and characterize the atmospheres of terrestrial planets orbiting M dwarfs (M-Earths). The existence of atmospheres on M-Earths is highly uncertain because […]

Geodynamics Of Super-Earth GJ 486b
Many super-Earths are on very short orbits around their host star and, therefore, more likely to be tidally locked.

A Water-Rich Atmosphere or Stellar Contamination for the Warm Super-Earth GJ~486b from JWST Observations
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 transmission spectroscopy, facilitating atmospheric […]

High-Resolution Transmission Spectroscopy of the Terrestrial Exoplanet GJ 486b
Terrestrial exoplanets orbiting M-dwarf stars are promising targets for transmission spectroscopy with existing or near-future instrumentation.
