On the Rapid Spin-down and Low Luminosity Accretion in AE Aqr
AE Aqr is an unusual close binary system with a large spin-down rate,
a relatively low quiescent luminosity, and clear pulse signals. We
consider an unconventional picture of AE Aqr in which an accreting
white dwarf is rapidly spun-down via gravitational radiation emission
and the accretion proceeds at high altitudes while bulk of inflowing
material is ejected in a propeller-like manner. We discuss spread of
the accreted matarial on the magnetic poles in the presence of a strong
magnetic field. Implications on emisison spectra and time variabilities
are also discussed.
