In D "or rapidly spinning collapsed star" is not a modifier, correct? Therefore does not refer to the "first pulsar" Right?
Ron：you know, i don't really know how you would classify that construction. it probably doesn't count as a modifier, because it doesn't actually modify the noun -- i.e., it doesn't expand upon, restrict, or change the meaning of the noun in any way, as modifiers do.
in any case, regardless of how you may or may not choose to classify it, you should know what this sort of construction (comma + OR + words) does: basically, it provides a definition of the word that comes before it.
e.g.
an own-goal, or goal accidentally scored in one's own net and counting towards the other team's score, is possibly the most embarrassing feat that a soccer player can accomplish.
here, the words following "or" (goal accidentally ... score) are the definition of the term "own-goal".

disclaimer:
the above usage is definitely not the only use of "comma + OR"; a much more common use for that construction is as a conventional conjunction, connecting two parallel structures. however, you should know this less common construction, so that you don't immediately mark it as wrong upon seeing it.
