The Parker Instability in a Thick Gaseous Disk II: Numerical Simulations in 2D
Alfredo Santillan, Jongsoo Kim, Jose Franco +3
We present 2D, ideal-MHD numerical simulations of the Parker instability in a multi-component warm disk model. The calculations were done using two numerical codes with different a…
