The thermal structure of neutron stars with magnetized envelopes
is studied using modern physics input.
The relation between the internal ()
and local surface temperatures is calculated
and fitted by analytic expressions
for magnetic field strengths B from 0 to 1016 G
and arbitrary inclination of the field lines to the surface.
The luminosity of a neutron star with dipole magnetic field
is calculated and fitted as a function
of B,
, stellar mass and radius.
In addition, we simulate cooling
of neutron stars with magnetized envelopes.
In particular, we analyse ultramagnetized envelopes
of magnetars and also the effects of the magnetic field
of the Vela pulsar on the determination of
critical temperatures of neutron and proton superfluids
in its core.
Key words: stars: neutron / dense matter / conduction / magnetic fields
