HD 206893 B at High Spectral Resolution with the Keck Planet Imager and Characterizer

HD 206893 B at High Spectral Resolution with the Keck Planet Imager and Characterizer

We present an atmospheric characterization and orbital analysis of HD 206893 B, an exceptionally red, L/T-transition substellar companion in a multiplanetary system, via Keck Planet Imager and Characterizer (KPIC) high-resolution ( R ∼ 35,000) K- band spectroscopy. Using PHOENIX atmospheric models i...
