TL;DR: The LSST design is driven by four main science themes: probing dark energy and dark matter, taking an inventory of the solar system, exploring the transient optical sky, and mapping the Milky Way.

TL;DR: The Large Synoptic Survey Telescope (LSST) as discussed by the authors is a large, wide-field ground-based system designed to obtain repeated images covering the sky visible from Cerro Pachon in northern Chile.

TL;DR: Observations ofBeta Pictoris clearly detect the planet, Beta Pictoris b, in a single 60-s exposure with minimal postprocessing, and fitting the Keplerian orbit of Beta Pic b using the new position together with previous astrometry gives a factor of 3 improvement in most parameters over previous solutions.

TL;DR: The Gemini Planet Imager (GPI) as mentioned in this paper is a facility instrument under construction for the 8m Gemini South telescope that combines a 1500 sub-aperture AO system using a MEMS deformable mirror, an apodized-pupil Lyot coronagraph, a high-accuracy IR interferometer calibration system, and a near-infrared integral field spectrograph to allow detection and characterization of self-luminous extrasolar planets at planet/star contrast ratios of 10-7.

TL;DR: The Gemini Planet Imager (GPI) as discussed by the authors is a system for direct imaging of the planets themselves, which can achieve contrast levels of 10-7 to 10-8, sufficient to detect warm self-luminous Jovian planets.
