Observational constraints of exoplanet clouds

, 2023
We entered a new era in extrasolar planets characterisation. We are indeed given access to constraints on their meteorology. New facilities have been designed specifically for exoplanet atmospheric characterisation.

TransCom model simulations of hourly atmospheric CO2: Analysis of synoptic-scale variations for the period 2002-2003 [PDF]

, 2008
The ability to reliably estimate CO2 fluxes from current in situ atmospheric CO2 measurements and future satellite CO2 measurements is dependent on transport model performance at synoptic and shorter timescales.

Multiple Patchy Cloud Layers in the Planetary-mass Object SIMP 0136+0933

The Astrophysical Journal
Multiwavelength photometry of brown dwarfs and planetary-mass objects provides insight into their atmospheres and cloud layers. We present near-simultaneous J - and K _s -band multiwavelength observations of the highly variable T2.5 planetary-mass object,

The JWST Weather Report from the Isolated Exoplanet Analog SIMP 0136+0933: Pressure-dependent Variability Driven by Multiple Mechanisms

The Astrophysical Journal Letters
Isolated planetary-mass objects share their mass range with planets but do not orbit a star. They lack the necessary mass to support fusion in their cores and thermally radiate their heat from formation as they cool, primarily at infrared wavelengths ...

A Search for Temporal Atmospheric Variability of Kepler Hot Jupiters

The Astronomical Journal
We perform a systematic search for atmospheric variability in short-period gas-giant planets (hot Jupiters) observed by the Kepler mission, by looking for temporal variability of their secondary eclipse depths.

HET/HPF Observations of Helium in Warm, Hot, and Ultrahot Jupiters

The Astronomical Journal
The near-infrared helium triplet line is a powerful tool for studying atmospheric escape processes of close-in exoplanets, especially irradiated gas giants. Line profile fitting provides direct insight into the mechanisms driving atmospheric mass loss of

Effects of Transient Stellar Emissions on Planetary Climates of Tidally Locked Exo-Earths

The Astronomical Journal
Space weather events in exoplanetary environments sourced from transient host star emissions, including stellar flares, coronal mass ejections, and stellar proton events, can substantially influence a planet's habitability and atmospheric evolution ...

Time-resolved X-ray spectra of Proxima Centauri as seen by XMM-Newton

Astronomy & Astrophysics
Context. Stellar soft X-ray ([1, 100] Å) and extreme ultraviolet (also EUV, [100, 920] Å; jointly, XUV) radiation affect the evolution and chemistry of exoplanet atmospheres. It is, however, uncertain to what extent the radiation’s short-term variability
