Context. Young circumstellar disks are the birthplaces of planets. Their study is of prime
interest to understand the physical and chemical conditions under which planet formation …

Context. The census of stellar and substellar companions of nearby stars is largely
incomplete, in particular toward the low-mass brown dwarf and long-period exoplanets. It is …

Directly detecting thermal emission from young extrasolar planets allows measurement of
their atmospheric compositions and luminosities, which are influenced by their formation …

Context. The observation of planets in their formation stage is a crucial but very challenging
step in understanding when, how, and where planets form. PDS 70 is a young pre-main …

High-contrast adaptive optics (AO) imaging is a powerful technique to probe the
architectures of planetary systems from the outside-in and survey the atmospheres of self …

The Gemini Planet Imager is a dedicated facility for directly imaging and spectroscopically
characterizing extrasolar planets. It combines a very high-order adaptive optics system, a …

The spin of a planet arises from the accretion of angular momentum during its formation,,,
but the details of this process are still unclear. In the Solar System, the equatorial rotation …

Abstract The Exoplanet Orbit Database (EOD) compiles orbital, transit, host star, and other
parameters of robustly-detected exoplanets reported in the peer-reviewed literature. The …

Context. The β Pictoris moving group is one of the most well-known young associations in
the solar neighbourhood and several members are known to host circumstellar discs …

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 …
