Calculation of thermal conductivity of matter in magnetized neutron star. 
Abstract 
The solution of the system of Boltzmann equation for plasma in magnetic field is obtained by ChapmanEnskog method. Three functions, generalising Sonin polynomials are used for obtaining an approximal solution. Fully ionized plasma is considered. The tensor of the heat conductivity coefficients in nonquantising magnetic field is calculated. For nondegenerate and strongly degenerate plasma the asymptotic analytic formulae are obtained, which are compared with different results of previous authors. Due to kinetic approach, our results are more exact than usually used coefficients, obtained by a simplified approach for the thermal conductivity in a plasma of a neutron star crust. For strongly degenerate plasma Lorentz approximation, with neglecting of electronelectron encounters, is asymptotically exact, and our 3functional approximate solution gives results which deviate from an exact solution less than 3% for all values of the magnetic field. The deviation decreases with increasing of the field.
