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: Nielsen et al. as discussed by the authors presented a statistical analysis of the first 300 stars observed by the Gemini Planet Imager Exoplanet Survey (GPEES) to infer the underlying distributions of substellar companions with respect to their mass, semimajor axis, and host stellar mass.

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.

TL;DR: In this paper, the first results from the polarimetry mode of the Gemini Planet Imager (GPI) were presented, showing that the disk exhibits surprisingly strong asymmetry in polarized intensity, with the west side 9 times brighter than the east side despite the fact that the east sides are slightly brighter in total intensity.
