In the current paper, we continue to announce new variable stars discovered in the frame of the KPS (Kourovka Planet Search). Detailed information about the project and about Algol-type eclipsing binaries we detected is provided in the first paper (Popov et al. 2015), and eclipsing binaries of β Lyrae and W Ursae Majoris- types are presented in the second paper (Popov et al. 2016).
This paper is dedicated to pulsating variables of the δ Scuti type. We discovered 27 such stars.
Each figure consist of three panels. In the upper part, we provide the power spectrum obtained using the on-line light curve analysis tool by Kirill Sokolovsky. The lower part of each figure has two panels. The star’s instrumental magnitude as a function of Julian Date is given in the left panel, and the phase-folded light curve is given in the right panel. We used red colour for R band, green colour for V band, and blue colour for B band data.
This work has been supported by Russian Foundation for Basic Research grants 14-02-31338 and, partially, 14-02-31056.
The authors wish to thank Dr. Kirill Sokolovsky for providing the on-line lightcurve analysis tool.
