Derived Parameter: Total Gas Pressure

Total Gas Pressure

The horizontal lines show the (constant) values of magnetic pressure for the representative field strengths chosen for each model, suggesting the height range for plasma beta = 1.

$\textup{P}=2nkT=2.76\times10^{-16}nT \ \ \mathrm{dyne\ cm^{-2}}$

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

Gas 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
