The Origin of Magnetars—The Role of Anisotropic neutron superfluid of Neutron Stars

Qiu-He Peng, Zhi-Quan Luo

Abstract


We estimate the strength of the induced magnetic field due to the Pauli paramagnetic moment of the 3P2 Cooper pairs for the anisotropic (3P2) neutron superfluid under the applied magnetic field (B0) in neutron stars. The induced magnetic field of the anisotropic (3P2) neutron superfluid is as follows. B(in)≈(1.9/T7B0 (T7 denotes the interior temperature of the neutron star in unit of 107 K), η = (m(3P2)/0.1 M)RNS,6−3. The induced magnetic field will gradually increase with the temperature of the neutron star decreasing in their late evolutionary stage. A magnetar may appear in a condition when T7<<η. The upper limit of the magnetic field for the magnetars is Bmax(in)(3P2)≈2.02×1014η.
