Query: Impact of rotation on the evolution of convective vortices in collapsing
  stars   We study the impact of rotation on the hydrodynamic evolution of convective
vortices during stellar collapse. Using linear hydrodynamics equations, we
study the evolution of the vortices from their initial radii in convective
shells down to smaller radii where they are expected to encounter the supernova
shock. We find that the evolution of vortices is mainly governed by two
effects: the acceleration of infall and the accompanying speed up of rotation.
The former effect leads to the radial stretching of vortices, which limits the
vortex velocities. The latter effect leads to the angular deformation of
vortices in the direction of rotation, amplifying their non-radial velocity. We
show that the radial velocities of the vortices are not significantly affected
by rotation. We study acoustic wave emission and find that it is not sensitive
to rotation. Finally, we analyze the impact of the corotation point and find
that it has a small impact on the overall acoustic wave emission.
