    Accretion disk
    Ok I have a few questions from an exam I took in my astronomy class that I was very unsure about. Thanks for you help!

    - How do the dynamics of dust in the accretion disk differ to that of the gas?
    =is it because the gas atoms do not collide with sold dust grains?

    -What shapes the outflow from accretion disks into bipolar jets?
    = is it because of the magnetic field

    - Chemical creating organic tar-like compounds that are unusual in normal environments on the Earth can occur in...
    = is it the bipolar outflows from a nebula accretion disk

    I believe the first one has something to do with pressure in the gas.

    The second one IS because of either magnetic field, ior the influence of a binary orbiter. (but magnetic field is the most common explanation).

    I'm not sure at all about your third one. I think outflows are mainly molecular gas, and not really tar like. But I can't think where it may be created.

    Hope this helped a bit :)
