A red giant star 1.5 stellar masses inflated to about 1/6th Mercury's distance. It appears heavier in lithium than average, which indicates it may have swallowed a Hot Jupiter. It also may contain a 1.6 MJ planet that circles the star at Mars-like distances in one of the most elongated orbits found every 771 days, evidence of a planetary disruption.
