Hello everybody,
It's me... again. But this time it's not for a question, it's for a mistake. I found that the following equation, A = ((1329x10^(-H/5))/D)^2 where A is the albedo, H is the absolute magnitude of the star and D is the diameter of the planet in kilometers, is entirely wrong. Using it with Sun and Earth, the result is A = ((1329x10^(-4.85/5)/12,756)^2 = 0.000124629 (the albedo of the Earth is supposed to be approximatively 0.35).
So I replaced the diameter by the surface facing the Sun, giving A = ((1329x10^(-H/5)/2piR)^2, but the formula is still wrong. There's another way to calculate the albedo (radiation reflected back to space/incident solar radiation), but I cannot find the equation. If someone has something about that, he's welcome.
Bye
