Direct Spectrum of the Benchmark T dwarf HD 19467 B
Justin R. Crepp, Emily L. Rice, AAron Veicht +18
HD 19467 B is presently the only directly imaged T dwarf companion known to induce a measurable Doppler acceleration around a solar type star. We present spectroscopy measurements…
Gemini Planet Imager Spectroscopy of the HR 8799 planets c and d
Patrick Ingraham, Mark S. Marley, Didier Saumon +43
During the first-light run of the Gemini Planet Imager (GPI) we obtained K-band spectra of exoplanets HR 8799 c and d. Analysis of the spectra indicates that planet d may be warmer…
S4: A Spatial-Spectral model for Speckle Suppression
Rob Fergus, David W. Hogg, Rebecca Oppenheimer +2
High dynamic-range imagers aim to block out or null light from a very bright primary star to make it possible to detect and measure far fainter companions; in real systems a small…
