Discovery of Romanov V20, an Algol-Type Eclipsing Binary in the Constellation Centaurus, by Means of Data Mining

TL;DR

This paper reports the discovery of Romanov V20, a large-amplitude Algol-type eclipsing binary in Centaurus, achieved through data mining of sky survey data, remote telescope observations, and data analysis.

Contribution

It introduces a novel data mining approach combined with observational data to identify and characterize a new eclipsing binary star.

Findings

Orbital period determined for Romanov V20

Eclipse durations and magnitude ranges measured

Multi-band photometric data analyzed

Abstract

I report my discovery of the large-amplitude Algol-type eclipsing binary system which was initially added to the AAVSO International Variable Star Index (VSX) under the designation of Romanov V20. I describe selection criteria for searching for variability among other stars, the search of photometric data from several sky surveys, and my observations using remote telescopes, and the analysis of the data in the VStar software. I find the orbital period, eclipse duration, and magnitude range in Johnson B, V and Sloan g, r, i bands for primary and secondary eclipses.
