Title: GPI detailed spectroscopic and astrometric characterization of HR 8799cde.
Abstract: We are proposing deep high signal-to-noise ratio (SNR) Gemini Planet Imager (GPI) Y, J, H and K1/K2 spectroscopy/photometry of the three inner planets of HR 8799. With GPI's superior contrast, and our advanced data reduction and analysis pipeline, these observations will revolutionize our understanding of the system’s planets by allowing, for the first time, detailed high-SNR near infrared spectroscopy of planet e, as well as complementary planet c and d spectroscopy at Y-, J-, H- and K-band. The data will also be used to derive highly accurate relative astrometry of the three planets, allowing for more precise orbital characterization and detection of acceleration, a key value to properly constrain the system’s orbital configuration.
