Understanding the Impacts of Stellar Companions on Planet Formation and Evolution: A Survey of Stellar and Planetary Companions within 25 pc
Lea A. Hirsch, Lee Rosenthal, Benjamin J. Fulton +10
We explore the impact of outer stellar companions on the occurrence rate of giant planets detected with radial velocities. We searched for stellar and planetary companions to a vol…
First detection of orbital motion for HD 106906 b: A wide-separation exoplanet on a Planet Nine-like orbit
Meiji M. Nguyen, Robert J. De Rosa, Paul Kalas
HD 106906 is a 15 Myr old short-period (49 days) spectroscopic binary that hosts a wide-separation (737 au) planetary-mass () common proper motion companion, H…
GPI 2.0: Upgrades to the IFS including new spectral modes
Mary Anne Limbach, Jeffrey Chilcote, Quinn Konopacky +9
The Gemini Planet Imager (GPI) is a high-contrast imaging instrument designed to directly image and characterize exoplanets. GPI is currently undergoing several upgrades to improve…
A significant mutual inclination between the planets within the Mensae system
Robert J. De Rosa, Rebekah Dawson, Eric L. Nielsen
Measuring the geometry of multi-planet extrasolar systems can provide insight into their dynamical history and the processes of planetary formation. Such measurements are challengi…
Towards a direct measure of the Galactic acceleration
Sukanya Chakrabarti, Jason Wright, Philip Chang +9
High precision spectrographs can enable not only the discovery of exoplanets, but can also provide a fundamental measurement in Galactic dynamics. Over about ten year baselines, th…
Multiband GPI Imaging of the HR 4796A Debris Disk
Christine H. Chen, Johan Mazoyer, Charles A. Poteet +36
We have obtained Gemini Planet Imager (GPI) J-, H-, K1-, and K2-Spec observations of the iconic debris ring around the young, main-sequence star HR 4796A. We applied several point-…
