The atmosphere of a brown dwarf or extrasolar giant planet controls the spectrum of
radiation emitted by the object and regulates its cooling over time. Although the study of …

Clouds, which are common features in Earth's atmosphere, form in atmospheres of planets
that orbit other stars than our Sun, in so-called extrasolar planets or exoplanets. Exoplanet …

We present a new set of solar metallicity atmosphere and evolutionary models for very cool
brown dwarfs and self-luminous giant exoplanets, which we term ATMO 2020. Atmosphere …

Transmission spectra are differential measurements that utilize stellar illumination to probe
transiting exoplanet atmospheres. Any spectral difference between the illuminating light …

Context. Clouds are ubiquitous in exoplanet atmospheres and they represent a challenge
for the model interpretation of their spectra. When generating a large number of model …

Thousands of transiting exoplanets have been discovered, but spectral analysis of their
atmospheres has so far been dominated by a small number of exoplanets and data …

Observations of exoplanet atmospheres have shown that aerosols, like in the solar system,
are common across a variety of temperatures and planet types. The formation and …

Abstract We present Hubble Space Telescope (HST) optical and near-ultraviolet
transmission spectra of the transiting hot Jupiter HD 189733b, taken with the repaired Space …

Using the integral field spectrograph OSIRIS, on the Keck II telescope, broad near-infrared H-
and K-band spectra of the young exoplanet HR8799b have been obtained. In addition, six …

Capitalizing on the observational advantage offered by its tiny M dwarf host, we present
Hubble Space Telescope/Wide Field Camera 3 (WFC3) grism measurements of the …
