GPI

Another week and yet another article based on GPI data has been accepted for publication. A team led by a European astronomer has analyzed observations of the planetary system named HD 95086, which has been known since last year for hosting an exoplanet, named HD 95086b. GPI data was extremely useful in confirming that the planet is co-moving with its star and in constraining its properties, such as its temperature and composition. HD 95086... read more ❯

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... read more ❯

Astronomers and engineers recently completed building the Gemini Planet Imager (GPI) to study distant solar systems. GPI will obtain high-resolution images of extrasolar planets by blocking the light of stars and detecting the faint thermal glow of orbiting planets. Since the first extrasolar planet was discovered in 1995, thousands of candidate extrasolar planetary systems have... read more ❯

Adapted from Boston Micromachines Corporation press release CAMBRIDGE, MA--(Marketwired - Feb 3, 2014) - Boston Micromachines Corporation (BMC), a leading provider of MEMS-based deformable mirror (DM) products, adaptive optics (AO) systems and scientific instruments, announced on Feb. 3 2014 that its 4K-DM is currently installed and is being used in the Gemini Planet Imager (GPI). Deployed on one of the world's largest telescopes, the 8-meter Gemini South telescope located in the Chilean Andes, GPI is a scientific instrument which detects light from extrasolar planets.

The Gemini Planet Imager (GPI) team held our latest science meeting November 1-2, 2013, right before GPI saw first starlight. The meeting was hosted by the SETI Institute at their office in Mountain View, CA (for those curious, I did not find any signs of aliens there). Continuing with tradition, we took a group picture of the GPI team. You can tell it has grown significantly from the past. Building an instrument as complex as the Gemini Planet Imager (GPI) and using it to directly image planets... read more ❯

In 2003, I was lucky enough to be part of a small group of astronomers that met at the University of California at Berkeley to brainstorm on an innovative idea: the design of an instrument to image and characterize planets around other stars, called exoplanets, using a telescope in the 8 – 10 meter class. A decade later, such an instrument became reality with the arrival of the Gemini Planet Imager (called also GPI, or “Gee-pie”) instrument at the Gemini South telescope in Chile. Five known planetary systems imaged with current adaptive optics systems. Fomalhaut shown on... read more ❯

Adapted from Gemini Observatory e-Newscast #53 Gemini's powerful new instrument for studying planets beyond the Solar System, the Gemini Planet Imager (GPI), has successfully received its first starlight for engineering and testing on the night of November 11-12. On-sky observations are currently ongoing for technical integration with the Gemini South telescope. The GPI team (Figure 1) began the 7-night observing run began with a head start, since preliminary pupil and pointing alignments were completed early, due to extensive preparatory work and smooth integration since the instrument arrived at Gemini South in August. Figure 1. The GPI commissioning team... read more ❯

Yesterday was a major milestone for the Gemini Planet Imager Project! Gaston Gausachs, mechanical engineer at Gemini Observatory, sent us this great picture ofGPI, our exoplanet camera hunter, mounted on the Gemini South Telescope. The team reported that it was a flawless and smooth operation. The 2-ton instrument is now attached to the Cassegrain focus of the telescope. The picture below shows  GPI on the bottom, and  CANOPUS on the left, GMOS on the right, two other instruments that can be operated at the Gemini South Telescope. We... read more ❯

Stephen Goodsell, Gemini Instrumentation Manager, surprised most of the Gemini Planet Imager (GPI) team on August 16 at 3am when we received in our mailbox his email announcing that GPI  landed to Chile. The crates containing the dismounted instrument (see our previous post) had been loaded in a Boeing 747 from Lan Chile and flew to Lima then Santiago (LA601). After quickly clearing customs, the local GPI team could inspect the crates and determined that they arrived in... read more ❯
