Transmission spectroscopy,–of exoplanets has revealed signatures of water vapour,
aerosols and alkali metals in a few dozen exoplanet atmospheres,. However, these previous …

Measuring the abundances of carbon and oxygen in exoplanet atmospheres is considered a
crucial avenue for unlocking the formation and evolution of exoplanetary systems,. Access to …

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 …

The Saturn-mass exoplanet WASP-39b has been the subject of extensive efforts to
determine its atmospheric properties using transmission spectroscopy,,–. However, these …

The population of planets smaller than approximately 1.7 Earth radii (R⊕) is widely
interpreted as consisting of rocky worlds, generally referred to as super-Earths. This picture …

Aims. We present a large atmospheric study of 49 gas giant exoplanets using infrared
transmission photometry with Spitzer/IRAC at 3.6 and 4.5 μm. Methods. We uniformly …

The critical first step in the search for life on exoplanets over the next decade is to determine
whether rocky planets transiting small M-dwarf stars possess atmospheres and, if so, what …

Aims. We present new gravity and limb-darkening coefficients for a wide range of effective
temperatures, gravities, metallicities, and microturbulent velocities. These coefficients can be …

Stellar limb darkening affects a wide range of astronomical measurements and is frequently
modelled with a parametric model using polynomials in the cosine of the angle between the …

Aims. The complex physics of close binary stars is made even more challenging by the
proximity effects that affect it. Understanding the influence of these proximity effects is one of …
