Gliese 86 orbit and evolution (Procyon-analogue?)

Orbital and Evolutionary Constraints on the Planet Hosting Binary GJ 86 from the Hubble Space Telescope

Further details about the properties of the white dwarf and its orbit. Orbit appears to be wider than previous estimates, though it is still rather unconstrained.

It seems the system is fairly similar to Procyon, where the white dwarf Procyon B shows signs of pollution by metal-rich material, probably from a reservoir of circumbinary material. Suggests that Procyon may host a failed/truncated planetary system.
