The turn-over scenario for white dwarfs and neutron stars
V. S. Geroyannis
We study numerically the so-called ``turn-over scenario'' for rotating magnetic white dwarfs and neutron stars. According to this scenario, the magnetic symmetry axis of the model…
Viscous dissipative effects in white dwarfs and neutron stars
V. S. Geroyannis, P. J. Papasotiriou, I. Valiaka
When a differentially rotating magnetic star undergoes ``turn-over'', i.e., its magnetic symmetry axis is inclining at a gradually increasing angle with respect to its invariant an…
A turn-over scenario for rotating magnetic white dwarfs: models with several values of mass, angular momentum, and magnetic field
V. S. Geroyannis, P. J. Papasotiriou
We study a white dwarf with differential rotation and magnetic field, for which the symmetry axis of the toroidal field, the magnetic axis of the poloidal field, and the principal…
The spin-down problem in the white dwarf of AE Aquarii: numerical study of a turn-over scenario
V. S. Geroyannis
The white dwarf in AE Aqr is observed to spin down at a steady time rate ~ 5.64*10^{-14} s s^{-1}, while at the same time its UV and X-ray accretion luminosities remain almost unch…
