    Abstract

    Among various types of astrophysical particle acceleration sites, one important prototype is rotation-powered pulsars, namely highly magnetized (1012 G) and rapidly rotating (1 sec) neutronstar. On the first successful detection of pulsating hard X-rays from AE Aqr,1 the possibility of particle acceleration in the magnetosphere was pointed out. We consider that such magnetized whited dwarfs have similar system as pulsars. The particles are accelerated by the electrostatic potential which is induced by a strong surface field but the accelation mechamism is still controversal. Here, for simplicity, we demonstrated particle simulation for isolated Rotationg White Dwarf magnetopshere. We considered the effect of higher order stellar magnetic field such as quadrupole magnetic field. Magnetic field is assumed to be dipole or quadrepole. The numerical code is originately developed for particle simulation for axissymetric pulsar magnetosphere.2,3 We have obtained steady solution with accelerating regions around the star. Because of superimposition of quadrepole field, the location of accelerating region differs around the equatorial plane in conrast to dipole magnetic field case.
