Directly detecting thermal emission from young extrasolar planets allows measurement of their atmospheric compositions and luminosities, which are influenced by their formation mechanisms. Using the Gemini Planet Imager, we discovered a planet orbiting the ~20-million-year-old star 51 Eridani at a projected separation of 13 astronomical units. Near-infrared(More)
SUMMARY The Gemini Planet Imager Exoplanet Survey (GPIES) has observed approximately 17% of the 600 targets in its 890 hour campaign to directly image young, massive exoplanets about nearby stars. We present an update of the pre-survey performance simulations using GPI's on-sky performance data in the form of post-processed, angular separation-dependent(More)
