Evolution of Accreting Neutron Stars' Magnetic Fields

This study by Ya. N. Istomin and P. N. Lebedev from the Physical Institute in Moscow, Russia, delves into the evolution of magnetic fields in accreting neutron stars, focusing on the depth of penetration into the crust, critical magnetic field values, and superconducting vortices. The research identifies the minimum magnetic field and reveals the core magnetic field reduction mechanism due to superconducting protons, providing insights into neutron stars' internal structure.
