Description
This project builds on prior work done determining the primary and Blazhko periods of the RR Lyrae star EY UMa. This year, data from the Catalina Real-Time Transient Survey (CRTS), NASA’s Transiting Exoplanet Survey Satellite (TESS), and the All-Sky Automated Survey for Supernovae (ASAS-SN) were analyzed to compare sky survey and satellite results with observations at the Paul P. Feder Observatory. The current estimate for the primary period of this star is 0.54906 ± 0.000023 days. With the aid of sky surveys, the current estimate for the Blazhko period was found to be 94.2 days. There is evidence that this star is experiencing phase modulation along with the amplitude modulation studied thus far, though more analysis is needed to determine its period.
