Martian core heat flux: Electrical resistivity and thermal conductivity of liquid Fe at Martian core PT conditions
The present-day Mars has no magnetic field which suggests that the heat carried out of its
liquid core is largely driven by conduction. To constrain the heat flux from Martian core, we …
