I am not an astronomer, so I didn't know that this is what this equation is called. There is something new to learn every day. | |
| Jan 16 at 21:50 | comment | added | FlatterMann | For spherical shells the gravity at a given radius is given by the total mass inside that shell. The problem with numerical calculations for gravity acting on compressible matter is that it has to be self-consistent. The gravity depends on the density function rho(r), but the density function rho(r) also depends on the gravity. In astronomy the problem of hydrostatic equilibrium of compressible bodies is associated with the term "polytrope". I found e.g. web.gps.caltech.edu/classes/ge131/notes2016/Ch9.pdf discussing this. | |
