First light of the Gemini Planet Imager
TLDR
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.

Discovery and spectroscopy of the young jovian planet 51 Eri b with the Gemini Planet Imager
TLDR
Using the Gemini Planet Imager, a Jupiter-like planet is discovered orbiting the ~20-million-year-old star 51 Eridani at a projected separation of 13 astronomical units and has a methane signature and is probably the smallest exoplanet that has been directly imaged. Expand
Probing for Exoplanets Hiding in Dusty Debris Disks: Disk Imaging, Characterization, and Exploration with HST/STIS Multi-Roll Coronagraphy
Spatially resolved scattered-light images of circumstellar (CS) debris in exoplanetary systems constrain the physical properties and orbits of the dust particles in these systems. They also inform onExpand
Probing dust grain evolution in IM Lupi's circumstellar disc. Multi-wavelength observations and mo
Aims. We present a panchromatic study, involving a multiple technique approach, of the circumstellar disc surrounding the T Tauri star IM Lupi (Sz 82). Methods. We have undertaken a comprehensiveExpand
RULING OUT STELLAR COMPANIONS AND RESOLVING THE INNERMOST REGIONS OF TRANSITIONAL DISKS WITH THE KECK INTERFEROMETER
With the Keck Interferometer, we have studied at 2 {mu}m the innermost regions of several nearby, young, dust-depleted 'transitional' disks. Our observations target five of the six clearest cases ofExpand
Mid-infrared size survey of young stellar objects : description of keck segment-tilting experiment and basic results
The mid-infrared properties of pre-planetary disks are sensitive to the temperature and flaring profiles of disks for the regions where planet formation is expected to occur. In order to constrainExpand
The Gemini Planet Imager Exoplanet Survey: Giant Planet and Brown Dwarf Demographics from 10 to 100 au

The Structure of High Strehl Ratio Point-Spread Functions
We describe the symmetries present in the point-spread function (PSF) of an optical system either located in space or corrected by an adaptive optics (AO) system to Strehl ratios of about 70% andExpand
The Solar-System-Scale Disk around AB Aurigae
The young star AB Aurigae is surrounded by a complex combination of gas-rich and dust-dominated structures. The inner disk, which has not been studied previously at sufficient resolution and imagingExpand
