Ultra-compact Double Degenerate Binaries: Gravitational Waves, X-rays and Masers

K. Wu, G. Ramsay, A. Willes

Abstract

We present a model for unipolar induction in ultra-compact double
degenerate binaries consisting of a white-dwarf pair. The power
generated by ohmic dissipation of the electric currents driven by
unipolar induction is calculated. The orbital dynamics of these
ultra-compact systems is investigated, and their gravitational radiation
is determined. We also discuss how electron-cyclotron masers develop
when unipolar induction operates in ultra-compact double degenerate
binaries and related objects, such as the white-dwarf planetary systems.
