... where Rme = L e V Ae /η, V Ae is the Alfvén speed in the inflow region, and η is the magnetic diffusivity of the plasma. In astrophysical plasmas Rme is typically 106 to 1012 , so Sweet-Parker-type reconnection is very slow (M Ae ≈ 10−3 to 10−6 ) compared to the rates needed to explain the rapid re ...
