At the dawn of the first discovery of exoplanets orbiting Sun-like stars in the mid-1990s, few
believed that observations of exoplanet atmospheres would ever be possible. After the 2002 …

Adaptive optics is a prime example of how progress in observational astronomy can be
driven by technological developments. At many observatories it is now considered to be part …

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 …

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 …

The search for life in the Universe is a fundamental problem of astrobiology and modern
science. The current progress in the detection of terrestrial-type exoplanets has opened a …

Abstract We present the Vortex Image Processing (VIP) library, a python package dedicated
to astronomical high-contrast imaging. Our package relies on the extensive python stack of …

We present the direct-imaging discovery of a substellar companion in orbit around a Sun-
like star member of the Hyades open cluster. So far, no other substellar companions have …

We present results from a high-contrast adaptive optics imaging search for giant planets and
brown dwarfs (≳ 1 M Jup) around 122 newly identified nearby (≲ 40 pc) young M dwarfs …

A direct image of an exoplanet system is a snapshot of the planets and disk around a central
star. We can estimate the orbit of a planet from a time series of images, and we can estimate …

Tremendous progress in the science of extrasolar planets has been achieved since the
discovery of a Jupiter orbiting the nearby Sun-like star 51 Pegasi in 1995. Theoretical …
