- TL;DR Summary
- I followed Schutz derivation and I don't get his result
Schutz finds that the orbital period for a circular orbit in Schwarzschild is
He gets this from
Where previously he had and and where
and
After doing the algebra I don't get that expression for the period (I get a much more complicated expression).
I punched in some numbers for M and r in a spreadsheet and the period given by the expression above does not match the calculations I have done. It does not even seem to be a very good approximation. Help, please!
