TL;DR

This paper presents new CCD BVR light curves and initial orbital parameter estimates for the eclipsing binary NSV 5904, obtained with the 1.88-m Kottamia Telescope during its testing phase.

Contribution

It provides the first detailed photometric observations and preliminary modeling of NSV 5904 using the Kottamia Telescope's CCD data.

Findings

New BVR light curves of NSV 5904 are constructed.

Times of minima and epoch are determined.

Preliminary orbital and physical parameters are estimated.

Abstract

New BVR light curves of the eclipsing binary system NSV 5904 have been constructed based on CCD observations obtained using 1.88-m telescope of Kottamia observatory during the phase of telescope testing and adjusting its optical quality on May, 2009. New times of minima and epoch have been determined from these light curves. Using the Binary Maker 3.0 (BM3) package, a preliminary determination of the photometric orbital and physical parameters of NSV 5904 are given.
