Homework Statement
Considering a two-body problem, star-planet, prove that the angular momentum of the planet is given by:
[tex]
\begin{equation}
{\cal L}_{e} = {\mu}\sqrt{GMa(1-e^2)},
\end{equation}
[/tex]
[tex]$\mu$[/tex] is the reduced mass
M is the star mass
a and e are the semi-major axis and eccentricity of the planet
The Attempt at a Solution
I have no idea how to start the problem. Can someone give me a light? what consideration should I make?
Thanks in advance
