Sun's 'Fingerprints' May Reveal Ancient Planet Swallowing

Professor Mutlu Yildiz of Ege University led research using the MESA stellar-evolution code, finding that a planet 5-10 times Earth's mass could explain long-standing discrepancies between solar models and observations, including the Sun's depleted lithium abundance.
