Distance Determination of RR Lyrae Stars AE Leo, AT Vir, and HY Com

Soper, C.; Tenenbaum, C.; Lounsbery, A. +2 more

We present the results of our observations and analyses of three RR Lyrae variable stars: AT Vir, HY Com, and AE Leo, in order to test period-luminosity relationships derived from stellar models. We have measured the periods of these stars to be 0.52359, 0.44898, and 0.63021 days, respectively, closely matching previous work. Period-Luminosity-Met…

BViz Photometry of the RR Lyrae Star RU Ceti

Fickle, J.; Allen, M. L.

The RR Lyrae star RU Cet was observed between October 26 and November 23, 2020. The observations were taken in the B, V, ip, and zs filters, with the telescope images being analyzed using various aperture photometry methods. The period of variation for RU Cet was found to be 0.585 ± 0.020 day. Theoretical period-luminosity-metallicity relations in…
