About the Twin Stars and Planetary Ingestion:
- The study focuses on pairs of stars formed within the same interstellar cloud, sharing identical chemical makeup, mass, and age, known as “twin” stars.
- While moving together within the Milky Way galaxy, these pairs are not binary systems gravitationally bound to each other.
- In seven pairs, one star exhibited evidence of ingesting a planet, evidenced by changes in its chemical composition.
