Can the rapid braking of the white dwarf in AE Aquarii be explained in terms of the gravitational wave emitter mechanism?
Astrophys.J. 576 (2002) L57 The spin-down power of the white dwarf in the close binary AE Aquarii significantly exceeds the bolometric luminosity of the system. The interpretation of this phenomenon in terms of the gravitational-wave emitter mechanism has been recently suggested by Choi & Yi. Th...

| description | Astrophys.J. 576 (2002) L57 The spin-down power of the white dwarf in the close binary AE Aquarii
significantly exceeds the bolometric luminosity of the system. The
interpretation of this phenomenon in terms of the gravitational-wave emitter
mechanism has been recently suggested by Choi & Yi. The basic assumption of
their interpretation is that the spatially limited blobs or mounds of the mass
\delta m ~ 10^{-3} M_sun, are present at the magnetic poles of the white dwarf.
We show that the mounds of this mass can be confined by the magnetic field of
the white dwarf only if the dipole magnetic moment of the star exceeds
4x10^{37} G cm^3. Under these conditions, however, the magnetodipole losses of
the white dwarf would exceed the evaluated spin-down power 6 orders of
magnitude. On this basis we discard a possibility that the observed rapid
braking of the white dwarf in AE Aquarii can be explained in terms of the
mechanism proposed by Choi & Yi. |
