Abstract Study Analysis Group 21 (SAG21) of NASA's Exoplanet Exploration Program
Analysis Group was organized to study the effect of stellar contamination on space-based …

Population studies of exoplanets are key to unlocking their statistical properties. So far, the
inferred properties have been mostly limited to planetary, orbital, and stellar parameters …

We provide a database of transit times and updated ephemerides for 382 planets based on
data from the NASA Transiting Exoplanet Survey Satellite (TESS) and previously reported …

Precise measurements of chemical abundances in planetary atmospheres are necessary to
constrain the formation histories of exoplanets. A recent study of WASP-127 b, a close-in …

We present analysis of the atmospheres of 70 gaseous extrasolar planets via transit
spectroscopy with Hubble's Wide Field Camera 3 (WFC3). For over half of these, we …

Atmospheric characterization of temperate, rocky planets is the holy grail of exoplanet
studies. These worlds are at the limits of our capabilities with current instrumentation in …

Context. Ultra-hot Jupiters are the hottest exoplanets that have been discovered so far.
Observations begin to provide insight into the composition of their extended atmospheres …

We present a study on the spatially scanned spectroscopic observations of the transit of GJ
1132 b, a warm (∼ 500 K) super-Earth (1.13 R⊕) that was obtained with the G141 grism …

The ExoClock project is an inclusive, integrated, and interactive platform that was developed
to monitor the ephemerides of the Ariel targets to increase the mission efficiency. The project …

Exoplanet atmosphere studies are often enriched by synergies with brown dwarf analogs.
However, many key molecules commonly seen in brown dwarfs have yet to be confirmed in …
