Abstract

Pondering Pulsars Pulsars are rapidly rotating, magnetized neutron stars that are powered by the loss of rotational energy. Because their emission is beamed, their light appears to pulse on and off at regular intervals. Changes in radio emission behavior have been observed for a number of pulsars, manifesting themselves as switches between ordered and disordered variations in intensity and pulse shapes, but these changes have not been seen at other wavelengths. Based on simultaneous radio and x-ray observations of pulsar PSR B0943+10, Hermsen et al. (p. 436 ) show that changes in emission state identified in radio measurements show counterpart fluctuations in the strength and temporal behavior of x-rays. Some of these changes were unexpected in their character and physical properties, challenging pulsar emission theories.
