SMS Γ=1.345, a/M=0.75

Detail

In this case, the supermassive star is seeded with a poloidal dipole-like magnetic field that extends from the interior into the exterior. The stellar model with gas perturbation is described by a polytropic equation of state (EOS) with $\Gamma=1.345$, and the supermassive star initially rotates at $75\%$ of the mass-shedding limit. This EOS is most appropriate for stars with mass $M \sim 10^4 M_\odot$.
