To the best of my knowledge, stars go nova because they have finished their fuel, and they can no longer sustain fusion once they begin fusing iron. It seems unlikely that being hit by a shockwave would trigger that. If it stripped away a lot of fuel, it would probably cause the star to go the route of a white dwarf rather than explode, right?
