The Secular Decrease of Optical and X-Ray Luminosity of Pulsars

Abstract

If the optical and X-ray pulses of pulsars originate close to the velocity-of4ight radius, then the emitted power should be roughly proportional to (period)-10. The predicted decrease of the optical luminosity of NP 0532 is about 1 percent every 2 years. The Vela pulsar PSR 0833 could have an apparent magnitude of 25.
