Radius of a star as a function of wavelength
 
Hi all,

My question is, does the radius of a star vary significantly between different wavelengths? I am particularly interested in the 100 nm to 100 micron range. I found a paper by Paul Swanson on the radio band radius, but so far can find nothing which compares optical and infrared measurements.

In this wavelength range, most of the radiation comes from the photosphere, which I don't think would vary much in size as a function of wavelength
