Stars as Magnets

Lecture no. 21 from the course: The Life and Death of Stars

Stars as Magnets

Taught by Professor Keivan G. Stassun | 29 min | Categories: The Great Courses Plus Online Science Course

Because stars spin like dynamos, they generate magnetic fields—a phenomenon that explains many features of stars. See how the slowing rate of rotation of stars like the sun allows astronomers to infer their ages. Also investigate the clock-like magnetic pulses of pulsars, which were originally thought to be signals from extraterrestrials.
