Researchers have identified subtle chemical signatures—referred to as “fingerprints”—within the Sun’s interior that could indicate it once engulfed a planet. By analyzing solar oscillations and elemental abundances, they aim to determine whether the Sun’s composition bears the imprint of such a planetary ingestion event.
Background
During its early history, a star can migrate inward and potentially engulf close-in planets, leaving detectable changes in its chemical makeup. Detecting such changes in the Sun would provide a rare window into the Sun’s formative years.
