In a binary star-system, should one star go supernova, what would be the effect on the other star (provided the original doesn't become a black hole)?

So I had this thought pop into my head based on a few assumptions, which may not be correct.  

Assumption 1: Only stars massive enough will go supernova at the end of their life.

Assumption 2: Not all stars that go supernova will result in a black hole.

So this got me thinking, in a binary star system, should one star go supernova, and not turn into a black hole, what would be the effect on the other star?  

I am sure some things like relative mass enter the equations, but I'm curious as the sun is not a solid, if there are any models that would predict the after-effects.

Would the shock-wave propagate through the plasma of the other star in such a way where it doesn't inherently break it up, or would the supernova break up the other star in its entirety.

First, an aside on black holes: 

Whether the progenitor becomes a black hole or not is irrelevant - the gravitational fields of a star and a black hole of the same mass are the same outside the surface of the star. In other words, at large distances, it's just as easy to orbit a black hole as it is to orbit a star.


The companion star in a binary system typically survives the supernova but with a distorted orbit. Some may even be completely ejected from the system, and are no longer gravitationally bound. As you say, the orbital change you get depends upon relative masses of the stars. The supernova shock wave does blow some small amount of the material off the companion star, but the evolution of the star otherwise continues as normal.
