GJ 876 is a nearby M dwarf hosting four currently known extrasolar planets. We use the CHARA interferometric array to determine the stellar angular diameter. Coupled with trigonometric parallax values and literature photometry, we obtain direct estimates of the stellar physical size, surface temperature, luminosity, and location / extent of the system's habitable zone (HZ). We present our measurement results of the GJ 876 stellar astrophysical parameters and the location of the HZ relative to the planetary orbits.< Leer menos
