GoKawiilStudy suggests Sun may still carry chemical trace of a swallowed super-Earth
Researchers at Ege University modeled how the young Sun's evolution would change if it had absorbed a super-Earth-sized planet, and found the scenario helps resolve mismatches between standard solar models and real observations, including the Sun's depleted lithium and internal sound-speed profile. The team also found such a planet could pass through the Sun's outer layers while losing little mass, implying a lasting internal chemical signature.
GoKawiil's interpretation of the reporting above, not reported fact.
This offers a possible physical explanation for long-standing puzzles in solar physics that standard stellar models have struggled to resolve. If confirmed, it would mean stars can retain hidden evidence of planets they consumed early in their formation, giving astronomers a new way to study the frequency of planet-star collisions across the galaxy.
- A super-Earth-sized planet may have been swallowed by the young Sun.
- The event could explain the Sun's lithium depletion and internal structure anomalies.
- Consumed planets may leave detectable chemical fingerprints inside their host stars.
