On the nature of the Delta Scuti star 2MASS 20061714+3818456

Key Points

Frequency analysis shows a fundamental frequency of 4.5856 day−1, indicating significant pulsations in the star.
A mathematical model describes the stellar light curve, supporting its classification as a Delta Scuti variable star.
The analysis was based on observational data from the Maidanak Astronomical Observatory and TESS satellite.
The findings highlight the unique characteristics of DSCT variable stars, which exhibit short-period, small-amplitude pulsations.

Abstract

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.
