Article Description

Using Hubble Space Telescope Fine Guidance Sensor astrometry and previously published radial velocity measures, we explore the exoplanetary system HD 202206. Our modeling results in a parallax, milliseconds of arc, a mass for HD 202206 B of, and a mass for HD 202206 c of. HD 202206 is a nearly face-on G + M binary orbited by a brown dwarf. The system architecture that we determine supports past assertions that stability requires a 5:1 mean motion resonance (we find a period ratio,) and coplanarity (we find a mutual inclination,).
