Abstract

Stellar oscillations as magnetic probes Unlike magnetic fields on the surfaces of stars, those within a star have so far remained difficult to observe. Fuller et al. have developed a method of delving into the magnetic depths by exploiting the oscillations of red giant stars. A high magnetic field can cause sound waves to become trapped within the central regions of the star, damping certain vibration modes. Using seismological techniques, this suppression can help infer the core magnetic field for several red giants. Science , this issue p. 423
