Jupiter's Magnetodisc: The Radius Where Centrifugal Plasma Pressure Overtakes the Dipole Field

This paper computes jupiter's magnetodisc from stated published inputs, using algebraic relations whose every step is deposited as executable code. Across the cases computed, plasma dominates spans 0 to 1. The first case gives radius Rj 5; dipole pressure nPa 4.66e+03; plasma pressure nPa 27; plasma dominates False. The last case gives radius Rj 50; dipole pressure nPa 4.70e-03; plasma pressure nPa 0.27; plasma dominates True. The calculations are simulated and computed from the stated assumptions; they are not measurements. Where a comparison against the Aldred Limit density bound is made, the bound values used are 9.72e54 g per cubic centimetre for a neutron carrier and 2.87e48 g per cubic centimetre for an electron carrier, and the size of any separation found is reported plainly, including where the result is that the bound does not constrain the magnetospheric quantity in question.
