Solar-Wind Kinetic Power Intercepted by Planetary Magnetospheres: Cross-Sections Set by the Standoff Distance

This paper computes solar-wind kinetic power intercepted by planetary magnetospheres from stated published inputs, using algebraic relations whose every step is deposited as executable code. Across the cases computed, wind flux W m2 spans 3.00e-07 to 3.20e-03. The first case gives body Mercury; standoff Rp 0.99; intercepted power W 5.87e+10; wind flux W m2 3.20e-03. The last case gives body Neptune; standoff Rp 19.3; intercepted power W 2.13e+11; wind flux W m2 3.00e-07. 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.
