TL;DR

This paper introduces a new few-parameter phenomenological model for eclipsing binary and exoplanet transit light curves, achieving high accuracy and useful for classification, timing, and period analysis.

Contribution

The paper presents a novel minimal-parameter model that accurately fits observed light curves of eclipsing binaries and transiting exoplanets.

Findings

Achieves better than 1% fit accuracy to observed light curves

Enables effective classification and timing analysis

Facilitates detailed period studies

Abstract

We present a new few-parameter phenomenological model of light curves of eclipsing binaries and stars with transiting planets that is able to fit the observed light curves with the accuracy better than 1\% of their amplitudes. The model can be used namely for appropriate descriptions of light curve shapes, classification, mid-eclipse time determination, and fine period analyses.
