Quote:Bruce, For the benefit of other readers, could you outline the method for finding the minimum separation?
Quote:Why do you suppose it likely that one of the stars is a very close binary? I don't see any difficulty in imagining two single, early A stars of this separation being reasonably securely bound. Or if their separation along the line of sight is considerable, they could be unbound, now sharing common space motion.
Quote:Even though I have been somewhat aware of the fact (for many years) that most of what we can visually see of our own galaxy with modest equipment is very much "local", I find I am still getting used it.
