CHARACTERIZING TRANSITING EXOPLANET ATMOSPHERES WITH JWST [PDF]
ABSTRACT We explore how well spectra from the James Webb Space Telescope (JWST) will likely constrain bulk atmospheric properties of transiting exoplanets. We start by modeling the atmospheres of archetypal hot Jupiter, warm Neptune, warm sub-Neptune, and cool super-Earth planets with atmospheres that are clear, cloudy, or of high mean ...

Chemical modeling of exoplanet atmospheres
International audienceThe past twenty years have revealed the diversity of planets that exist in the Universe. It turned out that most of exoplanets are different from the planets of our Solar System and thus, everything about them needs to be explored ...

This perspective surveys emerging quantum and classical photonic applications across operating wavelengths and timescales, highlighting persistent technological gaps in integrated light sources. We examine the unique advantages of quadratic nonlinear photonics on the thin‐film lithium niobate (TFLN) platform and discuss strategies for realizing ...

The Impact of the Sulfur Allotropes and Sulfur Hydrides on the Venus Cloud Chemistry
Abstract Venus is home to vivid sulfur chemistry, with SO2 ${\text{SO}}_{2}$ as the major sulfur gas species and a global cloud layer between 47 and 70 km composed of H2SO4 ${\mathrm{H}}_{2}{\text{SO}}_{4}$ and H2 ${\mathrm{H}}_{2}$O. The chemistry in the clouds has been extensively studied with 1D models, but none is able to reproduce the three orders

Atmospheric circulation of exoplanets
To date, more than 5000 exoplanets and more than 2000 brown dwarfs have been confirmed, which shows rich diversities in many aspects. With the rapid growth of the planet family, both observational and theoretical research on exoplanet atmosphere is developing rapidly. This paper aims to review the progress of exoplanet atmospheric circulation research,

VAPORIZATION OF THE EARTH: APPLICATION TO EXOPLANET ATMOSPHERES [PDF]
Currently, there are about 3 dozen known super-Earth (M < 10 MEarth), of which 8 are transiting planets suitable for atmospheric follow-up observations. Some of the planets are exposed to extreme temperatures as they orbit close to their host stars, e.g., CoRot-7b, and all of these planets have equilibrium temperatures significantly hotter than the ...

High-Resolution Spectroscopy of Exoplanet Atmospheres
Over five thousand exoplanets have been discovered, but relatively little is known about their atmospheric properties and compositions. Characterizing exoplanet atmospheres is the most promising avenue through which we can learn more about exoplanets ...
