Stardial: A Drift-Scan Camera at UIUC Jim Bedient TOPS 2003 June 25, 2003 High-tech gear How Drift-Scanning Works What You Get What you can do Monitor Variable Stars Discover New Variable Stars Observe Small Solar System Bodies Observe Man-made anomalies such as satellites and airplanes Make observations of night-time cloud cover Caveat Emptor Not presently operational, archive mode only Not true R-band Limiting Magnitude m”R”=~12 Not “flat” – background is modeled, and a polynomial fit is subtracted from each image V838 Mon Images from HST V838 Mon Images from HST V838 Mon Images from HST V838 Mon Images from HST V838 Mon – A Peculiar VarStar A totally new addition to the astronomical zoo Transformed itself from a small underluminous star a little hotter than the Sun, to a highly-luminous, cool supergiant star undergoing rapid and complex brightness changes Getting Data Web or FTP Instructions on the site: http://www.astro.uiuc.edu/stardial/ Analysis Blinking and Photometry in Mira Using SIMBAD, VizieR to identify objects Plot Light Curves in Excel Gee, we taught you how to do all that!
