Giant planet vanishes from solar system
A recent astronomical study suggests that the Sun may have swallowed a large rocky planet during its early stages. It is estimated that its mass was between 5 and 10 times that of Earth. The study uses real-time simulation models to support the hypothesis that such a planet, which may have formed in the inner regions of the solar system before changing its trajectory and ending up engulfed by the Sun, could leave lasting effects on the Sun's internal structure. These effects include an increased abundance of heavy elements in certain regions and alterations in internal mixing processes. These scenarios help explain some of the observable differences between modern models of the Sun's internal structure and observational measurements, especially regarding the convection zone and the analysis of the lithium sample present. Although the results are not definitive, they provide a plausible hypothesis for understanding the Sun's development and structure, resulting from the formation and engulfment of some planets during the early stages of the solar system's evolution.
