Abstract:

Magnetorotational instability (MRI) is one of the most promising agents
significantly amplifying magnetic fields in (resulting from
rapidly rotating progenitors) core-collapse supernovae (CC-SNe).
The initial phase of the MRI (of the exponential growth) is well understood,
however its exact termination mechanism remains unknown.
In this talk, we present our newest results clearly indicating
that the MRI, given CC-SN conditions, is terminated by the parasitic
Kelvin-Helmholtz instability.
This allows us to set the limit on the maximum magnetic field amplification
by the MRI.
