Sun’s Hidden Meal: Could a Buried Planet Explain Its Lithium Mystery
TL;DR
New research proposes the Sun’s lithium-poor surface and discrepancies in the interior’s sound speed could be explained if the young Sun swallowed a rocky super-Earth about 5–6 times Earth’s mass, stirring its insides. The model reproduces known solar features like convection-zone depth and composition, and while not proven, it suggests a detectable fingerprint of such engulfment may exist for future observations.
