"Surprising Commonality: Stars Found to Have Ingested Planets"
A study of "twin" stars has revealed that some of them have ingested planets, indicating that planetary systems may be more unstable than previously thought. The research examined 91 pairs of stars with similar sizes and chemical compositions, finding evidence of planetary ingestion in seven of the pairs. Possible reasons for a planet being engulfed by its host star include orbital disturbances caused by larger planets or passing stars. This study sheds light on the instability of planetary systems and suggests that there may be more planetary exiles than previously suspected.
