Normally those are various pieces of metadata associated with a file that cannot be stored inside the file itself. They are given this _ prefix and the "." prefix to make them hidden. Usually they show up (or pollute) on any non-native HFS+ file system that a Mac connects to. If the Mac doesn't have the native file system it expects, it just stuffs all of this other data into this other file.
