The orbit of the exoplanet Beta Pictoris b – The first peer-reviewed article with GPI

Following our very successful first light observing runs in late 2013, the first publication based on Gemini Planet Imager observations is now complete!  It has been accepted for publication in the Proceedings of the National Academy of Sciencesas part of a special issue on exoplanets, and is now available on Astro-ph. We report in this publication the performance of the Gemini Planet Imager based on the first light tests. The first scientific result demonstrates that right from the start, GPI has been performing well enough to yield new insights into exoplanets: Our astrometric observations from November 2013  gave us important new information on the orbit of the planet Beta Pictoris b.

Gemini Planet Image joined the Cosmic Diary Network

The Gemini Planet Imager team is joining the Cosmic Diary Network. GPI is the next generation adaptive optics instrument being built for the Gemini South Telescope. The goal is to image extrasolar planets orbiting nearby stars. The GPI team will use this blog to show the progress on the development of this instrument and discuss the science results which will be obtained in 2013.
