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 …

Clouds and hazes are commonplace in the atmospheres of solar system planets and are
likely ubiquitous in the atmospheres of extrasolar planets as well. Clouds affect every aspect …

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 …

We present K-band interferometric observations of the PDS 70 protoplanets along with their
host star using VLTI/GRAVITY. We obtained K-band spectra and 100 μas precision …

Context. Methods used to detect giant exoplanets can be broadly divided into two
categories: indirect and direct. Indirect methods are more sensitive to planets with a small …

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 …

The hot Jupiter HD 189733b is the most extensively observed exoplanet. Its atmosphere has
been detected and characterized in transmission and eclipse spectroscopy, and its phase …

Context. β Pictoris is arguably one of the most studied stellar systems outside of our own.
Some 30 yr of observations have revealed a highly-structured circumstellar disk, with rings …

High-resolution images of the solar surface show a granulation pattern of hot rising and
cooler downward-sinking material–the top of the deep-reaching solar convection zone …
