DYNAMICAL INSTABILITY OF WHITE DWARFS AND BREAKING OF SPHERICAL SYMMETRY UNDER THE PRESENCE OF EXTREME MAGNETIC FIELDS

Massive, highly magnetized white dwarfs with fields up to

Magnetic dipole moment of soft gamma-ray repeaters and anomalous X-ray pulsars described as massive and magnetic white dwarfs

10^9

Magnetars and white dwarf pulsars

G have been observed and theoretically used for the description of a variety of astrophysical phenomena. Ultramagnetized white dwarfs with uniform interior fields up to

Particle acceleration and radio emission for SGRs/AXPs as white dwarf pulsars

INVESTIGATION OF THE EXISTENCE OF HYBRID STARS USING NAMBU–JONA–LASINIO MODELS

G, have been recently purported to obey a new maximum mass limit,

Radio pulsar death lines to SGRs/AXPs and white dwarfs pulsars

M_{\rm max}\approx 2.58~M_\odot

Ultra-high energy cosmic rays from white dwarf pulsars and the Hillas criterion

, which largely overcomes the traditional Chandrasekhar value,

SGRs/AXPs as Rotation-Powered Neutron Stars

M_{\rm Ch}\approx 1.44~M_\odot

Analysis of the properties of SGRs and AXPs with realistic neutron star configurations

. Such a much larger limit would make these astrophysical objects viable candidates for the explanation of the superluminous population of type Ia supernovae. We show that several macro and micro physical aspects such as gravitational, dynamical stability, breaking of spherical symmetry, general relativity, inverse

Ultra-magnetized white dwarfs are stable?
