Stars of Constellations exist in what Spiral Arm of the Milky Way Galaxy?

Ok, I should have been more specific at "binary stars". There are systems which are gravitationally bound and can be resolved by the naked eye. But gravitationally bound is not the point. If stars are so close that they interact with each other in a significant way (with mass flow, tidal forces or similar effects), you cannot resolve that system with the naked eye.

The event I witnessed was very different to a star shinning really brightly. It envolved two stars, that were position very close together. One in particular was flickering dull then bright on and off for about 10 seconds. Then the other one appeared to shoot at the other one, about 4-5 times. Then the star that did all the shooting exploded along the trajectory of the particles that it fired off and engulfed the entire star. It's quite difficult to explain. What do you think it was? I looked up a type m supernova, and the way it is described sounds very similar to what I witnessed.
