The nearby white dwarf/red dwarf pair 40 Eri BC

Listed in IVOA Registry (Virtual Observatory)

A new relative orbit solution with new dynamical masses is determined for the nearby white dwarf-red dwarf pair 40 Eri BC.

Description

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.
