By Franck Marchis, Senior research scientist
Originally published on cosmicdiary.org
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.
