cds-question@unistra.frinterferometrymultiple-starssolar-system-planetsWe measured the angular diameter of the exoplanet host star {epsilon} Eridani using the Navy Optical Interferometer. We determined its physical radius, effective temperature, and mass by combining our measurement with the star's parallax, photometry from the literature, and the Yonsei-Yale isochrones, respectively. We used the resulting stellar mass of 0.82+/-0.05M_{sun}_ plus the mass function from Benedict et al. to calculate the planet's mass, which is 1.53+/-0.22M_Jupiter_. Using our new effective temperature, we also estimated the extent of the habitable zone for the system.2012ApJ...744..138Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/744/138CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/612/481 : Optical brightness of epsilon Eri dust ring (Proffitt+, 2004)J/ApJ/701/1922 : Radio interferometric planet search.
