Measured flux times stellar cross-section
The argument
Because linked claim, and the measured flux multiplied by a compact star's geometric cross-section and integrated over gigayear lifetimes yields billions of impacts above collider energies, and given that linked claim, compact stars accumulate ultra-high-energy cosmic ray strikes at astrophysically significant rates.

The inference is simple arithmetic and goes through granting its premises: an observed flux times a cross-section times gigayear ages gives large impact counts. The observational premise linked claim is settled measurement, so the argument's weight rests on low-field white dwarfs admitting cosmic rays to their surfaces, which is well grounded in magnetic surveys. The caveat is scope: the arithmetic establishes the rate only where magnetic fields do not intervene, so it carries white dwarfs firmly and neutron stars only conditionally.
