Rotation speed vc[R]vc[R]
in reduced units for M33 looks like
0.342331 Sqrt[R^2/(0.728117 + R^2)^0.87955]
Knowing e=0.995e=0.995
, I am trying to get the density Rho[m]from the equation
vc[R]^2 == Integrate[(4 Pi Sqrt[1 - e^2] m^2 Rho[m])/ Sqrt[-e^2 m^2 + R^2], {m, 0, R}]
This equation comes from Galactic Dynamics Binney Tremaine 2008. (2.132)
Using trial and error, I obtain a "good" solution for Rho[m]Rho[m]
, but it is very time expensive.
Does anybody knows how to solve this equation to get Rho[m] ?Rho[m]
?
Thanks in advance.
