Force to Remove Hydrogen (toy model)
We use F ≈ ṁ · vesc at the photosphere. Enter a mass flow rate (ṁ).
How to use this:
Think of “mass flow rate” as how many kilograms of hydrogen you try to throw out of the Sun every second. Type a number (for example,
Think of “mass flow rate” as how many kilograms of hydrogen you try to throw out of the Sun every second. Type a number (for example,
1e9
means one billion kilograms per second) and press
Compute Force. The box will tell you the force, in newtons, that it would take to launch
that much hydrogen fast enough to escape the Sun’s gravity. The result is enormous – that’s the point.
