standard solar model, stellar structure
Hello. Hope you don't mind me leaving a message here. I've finished a re-write of standard solar model. I also worked a little on stellar structure. I noticed that mixing length theory is described as a phenomenological theory with two free parameters, which need to be set by fitting with observations. Not being an expert, wondered if there was any circularity in using a solar (or stellar) model to make predictions when observations are needed to calibrate it. Any constructive feedback would be welcome. Puzl bustr (talk) 20:13, 8 November 2009 (UTC)

File permission problem with File:Cartoon of coronal loops.png
Thanks for uploading File:Cartoon of coronal loops.png, which you've attributed to http://www.astroengine.net/astro/alfvenwave/thesis06.pdf.
