We report the first detection of CO emission at high spectral resolution in the day-side
infrared thermal spectrum of an exoplanet. These emission lines, found in the atmosphere of …

We report on Fe i in the dayside atmosphere of the ultra-hot-Jupiter WASP-33b, providing
evidence for a thermal inversion in the presence of an atomic species. We also introduce a …

The carbon-to-oxygen (C/O) ratio in an exoplanet atmosphere has been suggested as a
potential diagnostic of planet formation. Now that a number of exoplanets have measured …

We analyze light curves of 284,834 unique K2 targets using a Gaussian process model with
a quasi-periodic kernel function. By cross-matching K2 stars to observations from Gaia Data …

Most of the molecules detected thus far in exoplanet atmospheres, such as water and CO,
are present for a large range of pressures and temperatures. In contrast, metal hydrides exist …

While steady empirical progress has been made in understanding the structure and
composition of hot-planet atmospheres, direct measurements of velocity signatures …

The mass and distribution of metals in the interiors of exoplanets are essential for
constraining their formation and evolution processes. Never the less, with only masses and …

Exoplanet transmission spectra provide rich information about the chemical composition,
clouds, and temperature structure of exoplanet atmospheres. Most exoplanet transmission …

With a temperature akin to an M dwarf, WASP-33b is among the hottest Jupiters known,
making it an ideal target for high-resolution optical spectroscopy. By analyzing both …

Thermal dissociation and recombination of molecular hydrogen, H2, in the atmospheres of
ultra-hot Jupiters (UHJs) has been shown to play an important role in global heat …
