So very intriguing, and the discussions so far. It made me wonder it this might have been the way of our star in its birth, and had something to do with the clearing out of the cavity that we are in. Anyone?
I usually chime in, but the tantrums of baby stars are not my forte... Anyway. The Sun was probably born in a rather rich cluster which contained at least one star massive enough to go supernova. Hey, our Sun had an adventurous youth.
I want to point out that most stars are less massive than the Sun, so chances are that LDN 1471 is less massive than the Sun, in which case the Sun's babyhood was probably a little different from this one. Not too different, though.
But the bubble we are in has nothing to do with the Sun's birth. The Sun was born some five billion years ago, and it completes one orbit around the galaxy in about 250 million years, so if you're in the mood, you can figure out how many turns the Sun has made around the center of the Galaxy. I find it unlikely that even the supernova remnant of the Sun's now hopelessly scattered birth cluster remains after 5 billion years, and it is absolutely certain that nothing remains of the little bubble that our Sun carved out during its birth pangs.
Not that we have to slightest idea where to look for the site of our Sun's birth. But the chances that it just happens to be where we happen to be just now.... Naaaah.
