DESCRIPTION:Until recently\, numerical simulations of low-mass star format
 ion have been unable to produce large discs around a forming protostar.  T
 his contradicts observations. With the inclusion of non-ideal magnetohydro
 dynamics (MHD)\, large discs are now being formed in numerical simulations
 \, indicating the necessity of non-ideal MHD.  However\, the outcome is so
 mewhat dependent on initial conditions and free parameters\, indicating th
 e necessity of carefully choosing realistic parameters.  Finally\, if the 
 inclusion of non-ideal MHD can self-consistently re-introduce discs\, how 
 else does it affect the evolution of the disc?  Moreover\, what effect wil
 l it have on the formation of the protostar itself and the early evolution
  of its environment?\n\nIn this talk\, I will first introduce the history 
 and importance of star formation and non-ideal MHD.  I will then present t
 he results from our numerical smoothed particle hydrodynamics (SPH) simula
 tions of protostar formation\, focusing on the effect that non-ideal MHD h
 as on the formation and early evolution of discs\; I will also comment on 
 outflows\, magnetic walls and on the evolution of the first and second hyd
 rostatic cores themselves.  This will be followed by a discussion on star 
 & disc formation in low-mass clusters\, where I will show the importance o
 f modelling stars in a more realistic environment.
