Within the next few years, GAIA and several instruments aiming to image extrasolar planets
will be ready. In parallel, low-mass planets are being sought around red dwarfs, which offer …

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 …

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 computation of complex neutral/ionized chemical equilibrium compositions is invaluable
to obtain scientific insights of, for example, the atmospheres of extrasolar planets and cool …

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 …

We present new evolution sequences for very low mass stars, brown dwarfs, and giant
planets and use them to explore a variety of influences on the evolution of these objects …
