Scientific paper
I suggested a project for some undergraduate students in which HD68988, a star with suspected extrasolar planet, was to be viewed with an SBIG spectrograph and ST7 CCD. The main advantage of performing this observation in central Nebraska was the very dark sky here. The main purpose was to test the hypothesis that special spectral signature is associated with such stars. We encountered a major problem: The star was between 8th and 9th magnitude, and the pointing correction software for the 14" telescope malfunctioned. The extended observations needed could not be performed. As a "quick fix" we found the spectrum of three fairly typical stars: Capella, Spica and Betelgeuse. We then analyzed the data using the Microcal Origin software. This ended up being a very useful exersize in learning about detector calibration, detector response, peak finding and analysis, and earth atmospheric spectrum. The results were also used in correcting attitude problem. We offer this as a possible lab project for astronomy winter labs.
