Stars, like meticulous chefs, mix the ingredients of the galactic broth. But sometimes they toss whole planets into the dish. Astrophysicists found that only 3–9% of Sun-like stars indulge in planetary cannibalism. Our Sun is a conscientious cook; its recipe is dictated by the Galaxy itself. This modesty allows planets like Earth to exist.
🎯 A precision of 0.015 dex is equivalent to detecting one extra grain of salt in an Olympic swimming pool. This extreme sensitivity was achieved by comparing to the ideal standard—our Sun, whose spectrum was obtained from the reflection off the asteroid Vesta.
🎬 It's somewhat reminiscent of a 'Star Trek' plot where a star devours a planet. In reality, the process leaves only a subtle chemical trace that can be deciphered.
