Temperature is not directly used in Equation 1 as I wanted to show how minimal orbital velocity will influence the escape of Hydrogen from the atmosphere. I also wanted the equation to be usable for other star systems (variable L). When I did directly use temperature I had all the space-settler crazies arguing about temperature differentials and the greenhouse effect.
The frequency does play a role, however to include it you must take a multitude of other highly variable factors into account. I wanted to keep the equations easy, and use easily obtainable data, so I used averages for the solar "not-so-constant".
I'm currently working on an Equation that proves you can decrease a planet gravity and atmospheric pressure, by adding mass. I plan to use it to show how Venus can be terraformed without the need to land. This should remove the "Venu-cant-be-terraformed-because-of-its-air-pressure" arguement.
