A. Liakos, S. Varrias, P. Niarchos
TL;DR
This paper presents new photometric data and analysis of the eclipsing binary V566 Oph, including updated light curves, geometric parameters, and a discussion of period changes possibly due to Light-Time Effect.
Contribution
It provides the first detailed light curve analysis using Wilson-Devinney code and revisits period variation analysis for V566 Oph.
Findings
New CCD photometric observations obtained.
Updated geometric and photometric elements derived.
Discussion of period changes with possible Light-Time Effect.
Abstract
New CCD photometric observations of the eclipsing binary V566 Oph have been obtained. The light curves are analyzed with the Wilson-Devinney code and new geometric and photometric elements are derived. A new O-C analysis of the system is presented and apparent period changes are discussed with respect to possible Light-Time Effect in the system.
