Now on sabbatical, Mike Brown has recently reactivated his mainly Transneptunian blog. Here is a tasty two-parter on Sedna for starters: http://www.mikebrownsplanets.com/2010/10/t...ere-part-2.html

First week of the course and it is excellent; just got done watching a couple of lectures where Dr. Brown goes through how reflected light spectra work and how the formulas used to measure spectra can determine atmospheric composition, measure the proportion of water, and determine surface temperatures. What's really cool about it is how he works through the increasing complexity of functional form of the modelling process: e.g., how the fairly simple formula to determine surface temperature has to be modified for the angle of incidence of the Sun by a cosine term.
