To clarify why I mentioned the unconfirmed companions, they were a way to briefly say a few of the effects caused by a supernova on nearby objects.

<p>There is evidence Betelgeuse might go supernova "soon". Are there any stars in the vicinity of Betelgeuse that are close enough that they will be hit by the explosion of this supernova? What would be the effect on stars near Betelgeuse?</p>

<hr>

<p>A supernova "kicks" out the other star if it is in a binary pair, but Betelgeuse is not a binary, so <a href="https://physics.stackexchange.com/questions/25357/what-happens-to-the-neighboring-star-of-a-type-ia-supernova">this</a> doesn't quite answer the question. </p>

There have been 2 proposed spectroscopic companions, though never confirmed, traveling with Betelgeuse. These are thought to orbit the red supergiant. So when Betelgeuse eventually explodes, they would certainly be blasted by radiation, atmospheres could be damaged or completely destroyed, and would lose their host star sending them on a new trajectory through space.
