What to know about Astrophysics

Astronomers from Keele University and the University of Exeter have identified six red dwarf stars with unusual lithium levels, suggesting they may have engulfed Earth-like planets. The findings, published in Monthly Notices of the Royal Astronomical Society, provide evidence for theories regarding the early formation and evolution of planetary systems.

What happened

Red dwarf stars detected 'eating' Earth-like planets Gaby Clark Scientific Editor Robert Egan Associate Editor Astronomers have found some of the strongest evidence yet that stars can swallow their own planets.

Why it matters

A new study, published in Monthly Notices of the Royal Astronomical Society, supports the long-held belief that young stars are capable of "eating" nearby worlds as planetary systems form.

Common ground

Researchers from Keele University and the University of Exeter studied thousands of stars and found evidence that six different red dwarfs—the smallest, coolest, and most common type of star in the universe—had engulfed Earth-like rocky planets.
