"New Study: Some Twin Stars Are Planet-Eaters"

A study of 91 pairs of twin stars has revealed that some of them have ingested planets, indicating that other planetary systems are not as stable as our own. The study focused on co-natal stars with matching chemical compositions and sizes, and found evidence of planetary ingestion in seven of the pairs. Possible reasons for this phenomenon include orbital disturbances caused by larger planets or passing stars. This discovery highlights the unique stability of our solar system in the universe.

"Surprising Commonality: Planet-Eating Stars Among Billions"

A new study suggests that about one in every 12 stars may have swallowed a planet, based on the analysis of 91 pairs of stars using the Gaia satellite and other telescopes. This finding challenges the assumption of stable planetary systems like our own solar system being the norm and raises questions about the stability of planetary systems. The research implies that planetary ingestion may occur during the normal lifetime of a star system, possibly due to rogue planets colliding with stars, and suggests that many planetary systems may be unstable.

"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.
