A rapidly-rotating, lithium-rich giant star: planet accretion?

The Super Lithium-Rich Red Giant Rapid Rotator G0928+73.2600: A Case for Planet Accretion?

The rapid rotation and lithium enhancement might be caused by the star engulfing a planet: this would spin it up through conservation of angular momentum and cause lithium regeneration. If the lithium is caused by the planet simply dumping lithium into the star, it would be far more rich in lithium than the planets in our solar system.
