土耳其埃格大学教授穆特卢·耶尔迪兹及其团队的最新研究提出，太阳在早期可能吞噬过一颗超级地球，并在其内部留下了可检测的化学痕迹。1这项发表在《皇家天文学会月报》上的研究通过建模发现，太阳吞噬质量约为地球5至10倍的超级地球可以解释长期存在的太阳模型与观测之间的差异。1
该模型同时解释了太阳内部结构的变化以及太阳表面锂元素异常低耗竭的问题。1这一发现可能帮助解释为何其他恒星系统中存在超级地球，而我们的太阳系中却没有发现类似的行星。1
A new study published in the Monthly Notices of the Royal Astronomical Society proposes that the Sun may have consumed a super-Earth in its early history, leaving behind detectable chemical signatures within its interior 1. Researchers led by Mutlu Yildiz at Ege University in Turkey developed models suggesting that the Sun's engulfment of a super-Earth with a mass between 5 and 10 times that of Earth could explain long-standing discrepancies between solar models and observations 1.
The team's modeling accounts for both structural variations within the Sun and the anomalously low depletion of lithium on the solar surface 1. This finding may help resolve a puzzling asymmetry in planetary systems: while super-Earths appear common around other stars, none exist in our own solar system 1.
