This study presents a photometric analysis of the star 2MASS 20061714+3818456 based on observational data from the Maidanak Astronomical Observatory (MAO) and the Transiting Exoplanet Survey Satellite (TESS). Frequency analysis shows that the star exhibits pulsations at a fundamental frequency of f1= 4.5856 day−1, which corresponds to a period of P1= 0.21807465 days, has first and second overtones. The harmonic structure and shape of the light curve indicate that the object is a Delta Scuti- type (DSCT) variable star, which exhibits short-period, small-amplitude, non-radial pulsations. A mathematical model of the stellar light curve has been developed and equations describing its periodic harmonic magnitude variation have been presented, providing further evidence for its classification as a DSCT variable.
