Star Eats Planet, Prepares for Second Course!

Astronomers have observed a star, TOI-5882, approximately 1,300 light-years from Earth, exhibiting compelling evidence of having recently engulfed one of its planets. This phenomenon, known as planetary engulfment, leaves behind elemental signatures in the star's light. Scientists noted an unusually high concentration of lithium in TOI-5882, an element more abundant in planets than stars.

Researchers theorize that the star's massive brown dwarf companion, TOI-5882-b, may have gravitationally disrupted the planet's orbit, leading to its collision with the star. This event likely occurred within the last two billion years. The brown dwarf itself is predicted to be engulfed by the star in the coming millions of years, potentially much sooner than previously estimated.
