# Time-resolved CCD photometry and time-series analysis of RR Lyrae type RR Gem star

## TL;DR

This study provides detailed time-resolved photometry and analysis of the RR Lyrae star RR Gem, confirming its pulsation period, variability type, and fundamental mode pulsation characteristics.

## Contribution

It offers precise measurements of RR Gem's pulsation period, mean magnitudes, and confirms its variability type as RRab/BL with characteristic light curve features.

## Key findings

- Pulsation period of 0.39689 days
- Mean magnitudes: V=11.277, I=11.063 mag
- Confirmed RRab/BL variability type

## Abstract

We present the results of a time-resolved photometric and time-series analysis of a RR Lyrae type star RR Gem. The main results are as follows: We found RR Gem's pulsation period, 0.39689 d, and its V and I mean magnitudes, 11.277 (V) and 11.063 (I) mag respectively. We confirm its variability type as RRab/BL because of its showing the Bla$\breve{z}$ko effect and it also shows asymmetric light curves (steep ascending branches), periods from 0.3 to 1.0 days, and amplitudes from 0.3 to 2 mag. in V. They are fundamental mode pulsators.
