Over the last two decades, several thousand exoplanets have been identified, and their
study has become a high scientific priority. Direct imaging of nearby exoplanets and the …

Context. Ground-based high-dispersion (R~ 100 000) spectroscopy (HDS) is proving to be a
powerful technique with which to characterize extrasolar planets. The planet signal is …

Proxima Centauri b provides an unprecedented opportunity to understand the evolution and
nature of terrestrial planets orbiting M dwarfs. Although Proxima Cen b orbits within its star's …

Infrared detection and imaging are key enabling technologies for a vast number of
applications, ranging from communication, to medicine and astronomy, and have recently …

The characterization of exoplanets is critical to understanding planet diversity and formation,
their atmospheric composition, and the potential for life. This endeavour is greatly enhanced …

MagAO-X is an entirely new extreme adaptive optics system for the Magellan Clay 6.5 m
telescope, funded by the NSF MRI program starting in Sep 2016. The key science goal of …

The discovery of the exoplanet Proxima b highlights the potential for the coming generation
of giant segmented mirror telescopes (GSMTs) to characterize terrestrial—potentially …

We are still in the early days of exoplanet discovery. Astronomers are beginning to model
the atmospheres and interiors of exoplanets and have developed a deeper understanding of …

Adaptive Optics (AO) has become a key technology for the largest ground-based telescopes
currently under, or close to beginning of, construction. AO is an indispensable component …

The raw coronagraphic performance of current high-contrast imaging instruments is limited
by the presence of a quasi-static speckle (QSS) background, resulting from instrumental Non …
