Physical parameters of RR Lyrae stars in NGC 6171
D. Deras, A. Arellano Ferro, S. Muneer +2
We present an analysis of VI CCD time-series photometry of the globular cluster NGC 6171. The main goal is to determine individual physical parameters for single-mode RR Lyrae star…

B. Ulas, R. Michel, S. Silva
The first multicolor observations and light curve solutions of the stars 1SWASP J130111.22+420214.0 and 1SWASP J231839.72+352848.2 are presented. The estimated physical parameters…
Period changes in the RR Lyrae stars of NGC 6171 (M107)
A. Arellano Ferro, P. Rosenzweig, A. Luna +4
Based on photometric data obtained between 1935 and 2017, diagrams were built for 22 RR Lyrae stars in the globular cluster NGC 6171, leading to the discovery of secular peri…

The accretion disk in the post period-minimum cataclysmic variable SDSS J080434.20+510349.2
S. Zharikov, G. Tovmassian, A. Aviles +3
This study of SDSS0804 is primarily concerned with the double-hump shape in the light curve and its connection with the accretion disk in this bounce-back system. Time-resolved pho…
