Asked by Katrell

Why can't we use solar type stars as spiral tracers? What type of stars make good spiral tracers? Why? What characteristics do they have to perform this function?

I am unfamiliar with the term "spiral tracer" so had to look it up. It applies t "giant molecular clouds and HII regions". My guess is thet "solar type" (main sequence) stars are not found in such regions.
