Abstract
IN the theory proposed by Chiu et al.1,2 the radio emission from pulsars, which has a brightness temperature3 exceeding 1021 °K, is supposed to be radiation from electrons having kinetic temperatures ∼ 105 °K. This is a surprising suggestion because it is believed that incoherent processes cannot produce brightness temperatures in excess of the effective temperature of the radiating particles. Indeed, the belief that such a limit applies to incoherent synchrotron emission4 led to the dismissal of that mechanism for the pulsar radiation3. Hence it seems that this aspect of the new theory should be examined carefully.
