TL;DR

This study presents the first time-resolved CCD photometry and period analysis of the variable star NSV 13601, revealing its variability and multiple periodicities using observations and software analysis.

Contribution

First detailed time-series photometric analysis of NSV 13601, identifying its variability and multiple periodicities with new observational data.

Findings

Confirmed NSV 13601 as a variable star.

Identified multiple periods around 77.7 days and 49.6 days.

Provided mean magnitudes in V and I bands.

Abstract

We present the first results of a time-resolved CCD photometric and time-series analysis of NSV 13601, a variable star of Pegasus constellation. The 14" SCT of Maharaja Krishnakumarsinhji Bhavnagar University(MKBU) was used for observations. Analysis was performed both in Vstar and Period04 software and compared their results. The main results are as follows: From data analysis, it's period, $\sim$77.784 d(MKBU Data V)(VStar), $\sim$77.632 d(MKBU Data Ic)(VStar), $\sim$77.058 d(MKBU Data V)(Period04) and $\sim$49.560 d(MKBU Data Ic)(Period04). It's V and I mean magnitudes for MKBU Data are 12.203 (V) and 11.292 (I) mag respectively. We confirm it as a variable star. \keywords{Stars: individual: NSV 13601 --- stars: oscillations --- techniques: photometric.
