Abstract

A new relative orbit solution with new dynamical masses is determined for the nearby white dwarf-red dwarf pair 40 Eri BC. The period is 230.29+/-0.68 years. It is predicted to close slowly over the next half-century, getting as close as 1.32" in early 2066. We determine masses of 0.573+/-0.018 M_{sun}_ for the white dwarf and 0.2036+/-0.0064 M_{sun}_ for the red dwarf companion. The inconsistency of the masses determined by gravitational redshift and dynamical techniques, due to a premature orbit calculation, no longer exists.
