Possible Evidence for the Presence of Volatiles on the Warm Super-Earth TOI-270 b

The Astronomical Journal
The search for atmospheres on rocky exoplanets is a crucial step in understanding the processes driving atmosphere formation, retention, and loss. Past studies have revealed the existence of planets interior to the radius valley with densities lower than

Precise Constraints on the Energy Budget of WASP-121 b from Its JWST NIRISS/SOSS Phase Curve

The Astronomical Journal
Ultra-hot Jupiters exhibit day-to-night temperature contrasts upwards of 1000 K due to competing effects of strong winds, short radiative timescales, magnetic drag, and H _2 dissociation/recombination. Spectroscopic phase curves provide critical insights

The K2 and TESS Synergy. III. Search and Rescue of the Lost Ephemeris for K2's First Planet

The Astronomical Journal
K2-2 b/HIP 116454 b, the first exoplanet discovery by K2 during its Two-Wheeled Concept Engineering Test, is a sub-Neptune (2.5 ± 0.1 R _⊕ , 9.7 ± 1.2 M _⊕ ) orbiting a relatively bright ( K _S = 8.03) K-dwarf star on a 9.1 day period. Unfortunately, due

Main-sequence exoplanet systems: tidal evolution

The easiest exoplanets to detect are those that orbit very close to their hoststars. As a result, even though these planets are quite rare, they represent amajor fraction of the current exoplanet population. A side-effect of theproximity between the planet and the star is that the two have strong mutualinteractions through a number of physical ...
