'Fingerprints' inside the Sun could reveal if it once swallowed a planet
Scientists propose that subtle variations in the Sun’s chemical composition—its “fingerprints”—could indicate a past event where the star engulfed a planet. By analyzing isotopic ratios and elemental abundances in solar spectra, researchers aim to detect signatures left by planetary material. Confirming such a merger would improve understanding of stellar evolution and planetary system dynamics in the Milky Way.
