Description
Over the course of 2022, 2023 and 2024 we utilized the Paul P. Feder observatory in conjunction with data from several other sources to search for variable stars in a field located in the Constellation Boötes. The field had no known variables but using data from the Feder Observatory, AAVSO member Geoff Stone, and NASA’s TESS satellite, we have found several variable stars and have initial period estimates for them. During 2023 we selected eight promising stars based on data from our Feder Observatory, then during 2024 we obtained data from our observatory and NASA’s TESS Quick Look Pipeline (QLP) to complement our ground-based observations. Of the eight stars initially selected from our data as potential variable, 3 of them are variable according to TESS’s data. Utilizing a Lomb-Scargle periodogram we were able to estimate the period of these stars. All of the stars found thus far exhibit periods on the order of several days and magnitude changes of several millimagnitude. We are working to classify the stars.
