This poster will describe new simulations exploring the collection and analysis of CCD observations of variable stars. Users have the capability to register and blink simulated CCD fields to visually detect variable stars. They can then form differential magnitudes and apply a period search algorithm to the data. Light curves can be formed in real time with candidate periods selected from the power spectrum. Users are asked to determine the period, identify the type of each variable from the light curve, and measure the amplitude of the variation. Using simulated CCD frames allows several variables similar to known RR Lyraes, Cepheids, and eclipsing binaries to be placed in one field.
The Nebraska Astronomy Applet Project consists of high quality astrophysics simulations surrounded by variety of supporting materials. The resources include complete background information, student guides, instructor guides, and embedded assessment. These materials are publicly available at http://astro.unl.edu and are funded by NSF grant #0231270.
