Neutron Stars (NSs) are known to be among the objects with the highest magnetic fields in the universe. Although these objects are often described as cold objects, the effect of temperature on their interior structure becomes relevant when considering systems such as very young NSs of NS-NS mergers. Here we study the joint effect of very strong magnetic fields and finite temperatures on the interior compositions of NSs. We show how the effect of temperature dominates over the one of the magnetic fields when considering the internal pressure and energy density, but also how both effects need to be taken into account when the chemical composition is studied. NS matter is described within a relativistic mean field (RMF) approximation, including both models with non-linear meson terms or with density dependent nucleon-meson couplings.
