First light of the Gemini Planet Imager

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.
Journal ArticleDOI

Discovery and spectroscopy of the young Jovian planet 51 Eri b with the Gemini Planet Imager

Bruce Macintosh, +94 more
- 02 Oct 2015 - 
TL;DR: 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.
Journal ArticleDOI

AMBER, the near-infrared spectro-interferometric three-telescope VLTI instrument

Romain Petrov, +98 more
TL;DR: AMBER as mentioned in this paper is one of the VLTI instruments that combines up to three beams with low, moderate and high spectral resolutions in order to provide milli-arcsecond spatial resolution for compact astrophysical sources in the near-infrared wavelength domain.
Journal ArticleDOI

Discovery and spectroscopy of the young Jovian planet 51 Eri b with the Gemini Planet Imager

Bruce Macintosh, +94 more
TL;DR: In this paper, the Gemini Planet Imager was used to detect a planet orbiting the star 51 Eridani at a projected separation of 13 astronomical units, with a spectrum with strong methane and water vapor absorption.
Journal ArticleDOI

The Gemini Planet Imager Exoplanet Survey: Giant Planet and Brown Dwarf Demographics from 10 to 100 au

Eric L. Nielsen, +73 more
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.
