Abstract
Abstract 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; from these detections and our contrast curves we infer the underlying distributions of substellar companions with respect to their mass, semimajor axis, and host stellar mass. We uncover a strong correlation between planet occurrence rate and host star mass, with stars M * > 1.5 M ⊙ more likely to host planets with masses between 2 and 13 M Jup and semimajor axes of 3–100 au at 99.92% confidence. We fit a double power-law model in planet mass ( m ) and semimajor axis ( a ) for planet populations around high-mass stars (…
