Original · EN

We study partially ionized hydrogen plasma at temperatures T = 10⁵.⁵-10⁶.⁵ K and magnetic fields B = 10¹²-10¹³ G, typical of photospheres of isolated neutron stars. We construct an analytic model of the plasma free energy and derive a generalized Saha equation which is used to obtain the opacities.
