Many if not all stars form with others in a stellar nursery, often from the
shock of a nearby supernova, if my reading is correct.
So, why are we so relatively alone? Where did our sblings go? And where is
the remnant of our long-lost mother?
I expect 4.5 billion years of stellar drift and galactic orbital mechanics
have scrambled things pretty badly, but is there no trace of the Sun's
relatives to be found?.
