Estimated Magnetopause Standoff Distances for Five Hot and Warm Exoplanets Under Assumed Dipole Moments

This paper computes estimated magnetopause standoff distances for five hot and warm exoplanets under assumed dipole moments from stated published inputs, using algebraic relations whose every step is deposited as executable code. Across the cases computed, margin Rp spans 2.57 to 6.59. The first case gives planet HD 209458 b; orbit AU 0.047; assumed B0 nT 40000; wind pressure nPa 50; standoff Rp 4.83; margin Rp 3.83. The last case gives planet TRAPPIST-1 e; orbit AU 0.029; assumed B0 nT 31000; wind pressure nPa 30; standoff Rp 4.83; margin Rp 3.83. 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.
