Hi
I am have been looking into magnetic CV's and am unsure of something i hope some one can help. Considering only the specific angular momentum of accreting matter, would a polar (Magnetic CV) have a faster spin rate than a disk accreting CV?
I know that in magnetic polars the accretion of matter onto the WD is via an accretion column onto the pole regions of the WD rather than an accretion disk. I think i am right in thinking that this then means that the infalling material would have a higher specific angular momentum (because in the accretion disk torque would affect its angular momentum).
I have two questions
1) Does the material in the accretion column have a higher angular momentum than an accretion disk?
2) And because of the conservation of angular momentum does that mean that a magnetic CV without an accretion disk would spin faster than an accretion disk CV?
Thanks for your input.
