A Study Of Rr Lyrae Stars In The Globular Cluster Ic 4499, Anna Paola Mikler
Honors Theses
Observations of the globular cluster IC4499 were taken with the 1m telescope at Cerro Tololo and combined with archival data from multiple telescopes. These data were used to study the variable star population using CCD photometry, with observations in the U, B, V, R and I passbands. The period and the magnitudes have been measured for the RR Lyrae stars. We present light curves in all passbands for all 97 RR Lyrae stars. The magnitudes of the RR Lyrae stars are compared with those measured by Walker and Nemec (1996). The distribution of stars on the horizontal branch is compared …
