Stellar Theory

I know it might sound lame, but this weekend was very educational. I went to a Saturday "flight school" with Billy down at the airfield, had a business meeting with a "potential investor" and then rounded out the weekend with some stellar-atmospheres radiative transfer simulations. All in a good weekends work.... Though I felt pretty lame when I found myself pissed at IDL on Saturday night when I probably should have been enjoying the north shore.

Limb darkening!

A rotationally-broadened, limb-darkened, quasi-2D stellar atmosphere produces this model H-alpha line....
