In this work, we study the effects of temperature on magnetic white dwarfs.
We model their interior as a nuclei lattice surrounded by a relativistic free
Fermi gas of electrons, accounting for effects from temperature, Landau levels
and anomalous magnetic moment. We find that, at low densities (corresponding to
the outer regions of star), both temperature and magnetic field effects play an
important role in the calculation of microscopic thermodynamical quantities. To
study macroscopic stellar structures within a general-relativistic approach, we
solve numerically the coupled Einstein’s-Maxwell’s equations for fixed entropy
per particle configurations and discuss how temperature affects stellar
magnetic field profiles, masses and radii.
