A primary goal of exoplanet characterization is to use a planet’s current composition to understand how that planet formed. For example, the C/O ratio has long been recognized as carrying important information on the chemistry of volatile species. Refractory elements, like Fe, Mg, and Si, are usually not considered in this conversation because they condense into solids like Fe(s) or MgSiO3 and would be removed from the observable, gaseous atmosphere in exoplanets cooler than about 2000 K… 
Why is it So Hot in Here? Exploring Population Trends in Spitzer Thermal Emission Observations of Hot Jupiters Using Planet-specific, Self-consistent Atmospheric Models
Thermal emission has now been observed from dozens of exoplanet atmospheres, opening the gateway to population-level characterization. Here, we provide theoretical explanations for observed trends in
Evidence that the Hot Jupiter WASP-77 A b Formed Beyond Its Parent Protoplanetary Disk’s H2O Ice Line
Idealized protoplanetary disk and giant planet formation models have been interpreted to suggest that a giant planet’s atmospheric abundances can be used to infer its formation location in its parent
Five Key Exoplanet Questions Answered via the Analysis of 25 Hot-Jupiter Atmospheres in Eclipse
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 extracted
Mining the Ultrahot Skies of HAT-P-70b: Detection of a Profusion of Neutral and Ionized Species
With an equilibrium temperature above 2500 K, the recently discovered HAT-P-70b belongs to a new class of exoplanets known as ultrahot Jupiters: extremely irradiated gas giants with day-side

This work presents a reanalysis of the spectroscopic phase-curve observations of the ultrahot Jupiter WASP-103 b obtained by the Hubble Space Telescope (HST) and the Spitzer Telescope. Traditional 1D
TESS Giants Transiting Giants. II. The Hottest Jupiters Orbiting Evolved Stars
Giant planets on short-period orbits are predicted to be inflated and eventually engulfed by their host stars. However, the detailed timescales and stages of these processes are not well known. Here,
UV Absorption by Silicate Cloud Precursors in Ultra-hot Jupiter WASP-178b
Aerosols have been found to be nearly ubiquitous in substellar atmospheres 1,2,3 . The precise temperature at which these aerosols begin to form in exoplanets has yet to be observationally
UV absorption by silicate cloud precursors in ultra-hot Jupiter WASP-178b.
Aerosols have been found to be nearly ubiquitous in substellar atmospheres1-3. The precise temperature at which these aerosols begin to form in exoplanets has yet to be observationally constrained.
How drifting and evaporating pebbles shape giant planets
Upcoming studies of extrasolar gas giants will give precise insights into the composition of planetary atmospheres, with the ultimate goal of linking it to the formation history of the planet. Here,
Spitzer Phase-curve Observations and Circulation Models of the Inflated Ultrahot Jupiter WASP-76b
The large radii of many hot Jupiters can only be matched by models that have hot interior adiabats, and recent theoretical work has shown that the interior evolution of hot Jupiters has a significant


Origins of satellites
Satellites are an inevitable consequence of most plausible planetary accumulation processes. They can arise from gaseous or particulate circumplanetary disks, continuously fed during accretion of the
Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS)
Ultra-hot Jupiters offer interesting prospects for expanding our theories on dynamical evolution and the properties of extremely irradiated atmospheres. In this context, we present the analysis of
Physical Properties of Cometary Dust
Prior to the 1986 apparition of comet Halley, all attempts to determine the physical properties of cometary dust were limited to remote observations and the analysis of various particles captured by
