Course notes

These are all variations on the theme of solar and stellar spectrum formation.  The first course is an extensive text for bachelor students physics and astronomy. The second is a condensed version concentrating on the solar spectrum.  The third is an in-depth treatment at masters astrophysics or graduate student level.  The fourth is a summary for solar physicists.

Start with the first course if you don't know what the Wien approximation is.  Try the second course if you wonder about solar source functions.  Study the third if you need insight on the Lambda operator or NLTE radiative equilibrium.  The fourth was intended for IRIS spectrometrists and may cater to optically-thin coronal types.

I assert the moral right to be identified as the author of these notes.  I explicitly permit multiplication and distribution for non-commercial educational purposes.  I appreciate weblinks, citations, acknowledgements (but not sloppy stealing).  I also appreciate invitations to teach elsewhere
