TL;DR
This study analyzes the Algol-type binary system WZ Crv through two-color photometry, determining its orbital parameters, temperature estimates, and identifying a star spot causing phase curve asymmetry.
Contribution
It provides new observational data on WZ Crv, including orbital period, temperature estimates, and evidence of star spots, which were not previously documented.
Findings
Determined orbital period and its derivative.
Estimated component temperatures.
Detected star spot causing phase curve asymmetry.
Abstract
We present the results of two color VR observation of the Algol-type binary system WZ Crv (12h44m15.19s, -21d25m35.4s) which were obtained using the remotely controlled telescope TOA-150 of Tzec Maun Observatory. We determined the moments of individual minima, the orbital period and its derivative, the initial epoch, color indices V-R and temperature estimates of the components. Also we noticed that the phase curve is asymmetric: the second maximum is higher than the first one. It indicates that there is a spot in the photosphere of one of the stars in this system.
