Pulsation modes of three Delta Scuti stars using Kepler project data: KIC3429637, KIC10451090, KIC2987660

Abstract

We have analyzed the light curves of three $\delta$ Scuti stars that were observed by the Kepler Space Telescope. Data collected by the Kepler space telescope, as well as analysis of the light curve of each star and the use of online databases, have been utilized to achieve the objectives of this project. Data has been collected through Kepler's main mission. We compare both data that we get from the Lightkurve package of Python and the KASOC online data centre to verify the data. We select the necessary data like flux, observation date, and the spectral type of the stars. By investigating various types of pulsating variable stars, three Delta Scuti stars have been selected due to their flux, pulsating type, etc. It is observed that most of these stars are pulsating in the p-modes. However, the selected stars pulsate in both p-modes and (possibly) g-modes. We select these stars, due to the lack of articles about them. Furthermore, some physical properties of these stars are deduced from their light curves. In summary, the results of this study indicate that the stars KIC3429637 and KIC10451090 are pulsating only in p-modes, while KIC2987660 is pulsating both in p-modes and g-modes.
