Wind Mass-Loss Rates from Astrospheric Absorption: Per-Area Rates and Wind Densities at One Astronomical Unit

This paper examines astrospheric-absorption mass-loss rates and the per-unit-area comparison between stars for 61 Cygni A, epsilon Eridani, Proxima Centauri, xi Bootis A and EV Lacertae, using published input values and transparent formulae throughout. The headline computed results are: eps_eri_mdot_g_s = 6.000e+13; eps_eri_per_area_solar = 55.532; 61cyg_per_area_solar = 1.131. Each quantity bearing on astrospheric-absorption mass-loss rates and the per-unit-area comparison between stars is derived in the deposited calculation script from the stated inputs, so the full chain from published value to conclusion for 61 Cygni A, epsilon Eridani, Proxima Centauri, xi Bootis A and EV Lacertae can be audited and rescaled. The discussion of astrospheric-absorption mass-loss rates and the per-unit-area comparison between stars compares the outcomes with independent published estimates, identifies the input to which each result is most sensitive, and confines the conclusions to what the arithmetic supports. Where the computed values for 61 Cygni A, epsilon Eridani, Proxima Centauri, xi Bootis A and EV Lacertae confirm earlier estimates, the confirmation is meaningful because no adjustable parameter was available to force agreement on astrospheric-absorption mass-loss rates and the per-unit-area comparison between stars; where they differ, the size and likely origin of the difference are stated directly.
