, 2023 We report the optical properties of two haze analogous to those produced in temperate water-rich exoplanet atmospheres. Their optical constants (the real refractive indices, n, and the extinction coefficients, k) are derived from 0.4 to 28.6 μm, covering

Exoplanet atmospheres: physical processes
, 2010 Over the past twenty years, astronomers have identified hundreds of extrasolar planets--planets orbiting stars other than the sun. Recent research in this burgeoning field has made it possible to observe and measure the atmospheres of these exoplanets ...

, 2014 We present high resolution transmission spectra of giant planet atmospheres from a coupled 3-D atmospheric dynamics and transmission spectrum model that includes Doppler shifts which arise from winds and planetary motion. We model jovian planets covering

Global Chemical Transport on Hot Jupiters: Insights from the 2D VULCAN Photochemical Model
The Astrophysical JournalThe atmospheric dynamics of tidally locked hot Jupiters is characterized by strong equatorial winds. Understanding the interaction between global circulation and chemistry is crucial in atmospheric studies and interpreting observations.

Characterisation of exoplanet atmospheres using high-resolution spectroscopy
The characterisation of exoplanet atmospheres is crucial to understanding planet formation, the exploration of extreme atmospheric physics, finding habitable worlds, and searching for extraterrestrial life, but challenged by the overwhelming star-to ...

Atmospheric Circulation of Tide-Locked Exoplanets
Annual Review of Fluid Mechanics, 2019 Tide-locked planets are planets in which tidal stresses from the host star have spun down the planet's rotation to the point where its length of sidereal day equals its length of year. In a nearly circular orbit, such planets have a permanent dayside and a permanent nightside, leading to extreme heating contrasts.

Hot exoplanet atmospheres resolved with transit spectroscopy (HEARTS) : II. A broadened sodium feature on the ultra-hot giant WASP-76b [PDF]
, 2019 High-resolution optical spectroscopy is a powerful tool to characterise exoplanetary atmospheres from the ground. The sodium D lines, with their large cross sections, are especially suited to studying the upper layers of atmospheres in this context.
