Well, in supernovae the problem is heating rather than acceleration.
I wonder if anybody has run a hydrocode on what happens to a terrestrial
planet subjected to its sun going supernova? It would be interesting to
see if any material is ejected that is not subjected to extreme heating
and radiation. Not that planets orbiting stars able to supernova are
that likely to be filled with life - they have a very short lifespan.
