Congratulations to Riley Barrett for receiving 3rd place in the poster competition last Saturday during the Southern Connecticut State University Undergraduate Research and Creative Activity Conference!
"My poster is a demonstration of the work I've been doing for the past year on studying binary star systems that are difficult to resolve using typical methods." Riley said, describing her research.
"Our process, speckle imaging, includes taking many short exposure frames of a system, using autocorrelation to create an image from those frames, then identifying companion stars through visual analysis and spatial frequency analysis. This process is proving to be very useful in studying the properties of these systems as well as reconstructing their orbits."
Riley's project relied on data from the Differential Speckle Survey Instrument (DSSI) which was built right here at SCSU!
