Now that detection of gravitational-wave signals from the coalescence of extra-galactic
compact binary star mergers has become nearly routine, it is intriguing to consider other …

Exoplanetary science is on the verge of an unprecedented revolution. The thousands of
exoplanets discovered over the past decade have most recently been supplemented by …

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

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 …

Stellar limb darkening affects a wide range of astronomical measurements and is frequently
modelled with a parametric model using polynomials in the cosine of the angle between the …

The observed lifetimes of gaseous protoplanetary discs place strong constraints on gas and
ice giant formation in the core accretion scenario. The approximately 10-Earth-mass solid …

We describe a new method to achieve point-spread function (PSF) subtractions for high-
contrast imaging using principal component analysis that is applicable to both point sources …

Stellar multiplicity is a ubiquitous outcome of the star-formation process. The frequency and
main characteristics of multiple systems, and their dependence on primary mass and …

As planets form and grow within gaseous protoplanetary disks, the mutual gravitational
interaction between the disk and planet leads to the exchange of angular momentum and …
