AQ Leo with the MOST Satellite
Originally uploaded by Astro Guy.
This has been a good week. I've managed to figure out how to decorrelate the stray light signal from large amplitude pulsators. The attached image shows a 2 day blow up of a 35 day observing run on the double mode RR Lyra AQ Leo. It's an impressive target. The fourier transform shows over 30 frequencies which all be related to harmonics or combination frequencies of the main two modes (fundamental and first overtone). Now I'm racking my brain over a physical explanation for the combination frequencies - shock waves come to mind, but a difficult to model. I'll have to keep thinking about it.
