Hi,
Thanks for the reply. Although, I'm not sure you understand the problem.
Imagine looking down on top of a disk (with centre at R=0). Then imagine a body, somewhere on the disk (R \neq 0). This body is then given a 'kick' with velocity v0 in a direction determined by the "known angle" in...
Hi there,
I'm trying to determine the radial component of a velocity vector in a disk. The vector doesn't (necessarily) start from the centre of the disk and can be pointed in any direction. I've attached a .pdf with the schematics - it seems like a simple problem but it has me stumped...
I'm sure you've already checked this, but just in case, here's where to start:

For a good overview of magnetic fields associated with stars all along the HR diagram this is a good paper to start with...
