Hi Dave,
I need a dimensionless value based of physical parameters to differentiate between concentrated mass systems such as the solar system and dispersed mass systems such as a galaxy.
I do not understand your proposal. Although it is a dimensionless value, how can it be derived from...
I want to find a dimensionless value that differentiates between concentrated mass systems such as the solar system and dispersed mass systems such as a galaxy. I assume spherical and radial symmetry, consider both the cases for point masses or smooth mass distributions.
The only value I can...
It got one answer (the other one referred to a master's degree, and not a bachelor). I assume there are more than one university in Europe in which a bachelor in physics is taught in English, so a single university answer can be considered an unsufficiently answered post for the question posted.
The Kuzmin model is just one of many. If you want more precise approximations, there are many more for thickened disks. Im just looking for a more simple one than Kuzmin.
I am looking for bachelors of physics in Europe taught in english, excluding UK and Ireland.

Exponential decay of mass density from center.
Axisymmetric disk (not elliptical disk)
Surface density = mass density function, since I consider no thickness mass/distance^2
It is certainly not. I dont care much about the form of surface density (linear or exponential) as long as it is not a solid disk (which is a completely different case of study).
I am trying to understand gravity inside an exponential axysymmetric mass disk with no thickness.
I know there are exact solutions for this case, such as the Mestel disk or the Kuzmin model, but I want to work out a simpler solution.
I am approaching the subject by linear superposition. For a...
