Gemini Observatory reveals the GPI programs selected for 2014B

Some news from Gemini Observatory,

Gemini Observatory has revealed the list of observing proposals scheduled in 2014B (the second half of 2014)  that will use the GPI instrument. Those programs focused on the search for companions around nearby stars and also stars known to possess a disk and/or a planet by radial velocity. Other groups are using the quality of data provided by GPI to study planets already imaged with previous instruments, such as the HR8799 system and Beta Pic b. Their goal is the study the atmosphere of those planets and also to collect more astrometric positions to refine the orbit of the exoplanet.

GPI Prepping First Light at Cerro Pachon

Since the arrival of the Gemini Planet Imager (GPI) at Cerro Pachón, the GPI team had busy September and October months.  The instrument was reassembled, aligned, and cooled on September 6. The first “Chilean” image was collected on September 11 and on September 25 the system was bolted on the flexure rig. This is a useful configuration to test the flexure of the instrument and properly correct them before mounting it on the Cassegrain focus of the Gemini South Telescope.
