Photometric Study of RR Lyrae V0893 Her by a Student Research Team

Abstract:

RR Lyrae V0893 Her is a little-studied RR Lyrae star which exists in a binary star system. In an effort to determine the type of RR Lyrae star and to determine the period-luminosity relationships with different filters, light curves were created using V, B, i, and z filters. The research made use of the Las Cumbres Observatory telescope network and of the astrosource and autovar python scripts to create the light curves and verify the period of the star. Several types of photometry were examined and period folding was done using python coding. Comparisons to the theoretical models of the period-luminosity relationships for different filters were then carried out. This research was carried out as part of a student and educator research experience through the Our Solar Siblings program in Australia.
