摘要: We study the thermal structure and evolution of magnetars as cooling neutron stars with a phenomenological heat source in an internal layer. focus on effect magnetized (B & 10 14 G) non-accreted accreted outermost envelopes composed different elements, from iron to hydrogen or helium. discuss combined conduction neutrino emission outer star crust calculate dipole magnetic field for various locations layer, rates strengths. Combined effects strong fields light-element composition simplify interpretation our model: these allow one interpret observations assuming less extreme (therefore, more realistic) heating. Massive magnetars, fast their cores, can have higher surface luminosity.
