Hi Paul, I’m glad the discussion revived your grey cells! If you are interested in understanding my work in more detail then you’re very welcome to contact me at my email address above. I suppose I should try to get it reviewed by submitting a paper to a journal, the trouble is that it falls between two stools i.e. to basic for professional journals and a bit maths heavy for amateur journals. I would have thought though that the approach would be good for teaching the basics of stellar spectroscopy at undergraduate level in a similar way to being taught the Bohr model of an atom.
