Derived Parameter: Proton Pressure

Proton Pressure

BLURB

$\textup{P}_p=2n_pkT=2.76\times10^{-16}n_pT\ \ \mathrm{dyne\ cm^{-2}}$

where n is electron density and k is the Boltzmann's constant.

Electron pressures for Fontenla Model 1001 (blue), Model 1005 (red), and Model 1006 (green). Horizontal lines are the corresponding magnetic pressures (30 G for 1001, 300 G for 1005, and 1000 G for 1006).

Model 1001 Values Quiet Sun; B = 30 G

Model 1005 Values Facula; B = 300 G

Model 1006 Values Sunspot umbra: B = 1000 G
