Wednesday 21 Sep 2016On the formation of discs using non-ideal magnetohydrodynamics

Discs are observed to form around young stars. However, discs have historically failed to form in numerical simulations of star formation; this is known as the magnetic braking catastrophe. One possible solution is the inclusion of non-ideal magnetohydrodynamics (MHD).
I will discuss the three non-ideal MHD processes and examine impact that they have on star formation. There will be a focus on the Hall effect, since recent studies indicate that this is the dominate term in determining whether a disc forms or not.
