Scientists believe the Sun may have swallowed a planet the size of a super-Earth early in its history. This event would have occurred during the initial phases of solar system formation, when the young planetary system was still stabilizing. The hypothesis suggests that a significant rocky planet may have been incorporated into the star's interior.
A new study published recently proposes that an event of this type could have left detectable clues within the Sun. The researchers analyzed how traces of such a planetary ingestion event could remain hidden in the star's internal structure, potentially being identifiable with currently available observation and modeling techniques.
The investigation indicates that these "cosmic footprints" could still be visible today, millions or billions of years after the event occurred. Scientists are working on methods to detect these chemical and structural signatures that would have been preserved in the solar plasma over billions of years.
This type of research helps astronomers better understand the formation and evolution processes of planetary systems, including our own. The possibility of finding direct evidence of planetary ingestion events in the Sun represents a unique window into the remote past of the solar system.
