The Gemini Planet Imager (GPI) has as its science instrument an infrared integral field
spectrograph/polarimeter (IFS). Integral field spectrographs are scientificially powerful but …

Job enrichment is one method that has been used to increase employee satisfaction and
work motivation. Hackman and Oldham's (1976) job characteristics model has served as the …

Fomalhaut, a bright star 7.7 parsecs (25 light-years) from Earth, harbors a belt of cold dust
with a structure consistent with gravitational sculpting by an orbiting planet. Here, we present …

The Gemini Planet Imager is a dedicated facility for directly imaging and spectroscopically
characterizing extrasolar planets. It combines a very high-order adaptive optics system, a …

Directly detecting thermal emission from young extrasolar planets allows measurement of
their atmospheric compositions and luminosities, which are influenced by their formation …

We present a statistical analysis of the first 300 stars observed by the Gemini Planet Imager
Exoplanet Survey. This subsample includes six detected planets and three brown dwarfs; …

We present the highest fidelity spectrum to date of a planetary-mass object. VHS 1256 b is
a< 20 M Jup widely separated (∼ 8'', a= 150 au), young, planetary-mass companion that …

Orbiting planets induce a weak radial velocity (RV) shift in the host star that provides a
powerful method of planet detection. Importantly, the RV technique provides information …

NIRSPEC is a 1-5 um echelle spectrograph in use on the Keck II Telescope since 1999. The
spectrograph is capable of both moderate (R= λ/▵ λ~ 2000) and high (R~ 25,000) resolution …

We present the first results from the polarimetry mode of the Gemini Planet Imager (GPI),
which uses a new integral field polarimetry architecture to provide high contrast linear …
