Exoplanetary science is on the verge of an unprecedented revolution. The thousands of
exoplanets discovered over the past decade have most recently been supplemented by …

Close-in giant exoplanets with temperatures greater than 2,000 K ('ultra-hot Jupiters') have
been the subject of extensive efforts to determine their atmospheric properties using thermal …

Observations of transiting gas giant exoplanets have revealed a pervasive depletion of
methane,,–, which has only recently been identified atmospherically,. The depletion is …

Theoretical studies of giant planet formation suggest that substantial quantities of metals—
elements heavier than hydrogen and helium—can be delivered by solid accretion during the …

A new piece of evidence supporting the photoevaporation-driven evolution model for low-
mass, close-in exoplanets was recently presented by the California–Kepler Survey. The …

Helium is the second-most abundant element in the Universe after hydrogen and is one of
the main constituents of gas-giant planets in our Solar System. Early theoretical models …

High-resolution spectroscopy (R≥ 25,000) has recently emerged as one of the leading
methods for detecting atomic and molecular species in the atmospheres of exoplanets …

We present an update of the open-source photochemical kinetics code VULCAN to include
C–H–N–O–S networks and photochemistry. The additional new features are advection …

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 …

We present one of the most precise emission spectra of an exoplanet observed so far. We
combine five secondary eclipses of the hot Jupiter WASP-18b (T day∼ 2900 K) that we …
