Modelling light curves of binary systems: accounting for extended winds

TL;DR

This paper presents a simple synthesis model for eclipsing binary systems with stellar winds, demonstrating that wind parameters significantly influence light curve shapes, especially for systems like WR stars.

Contribution

The paper introduces a new model that incorporates stellar wind effects into light curve simulations of binary systems, highlighting their importance.

Findings

Wind parameters strongly affect light curve shapes.

Wind effects are essential for modeling binaries with WR stars.

Numerical simulations confirm the impact of winds on eclipse minima.

Abstract

We suggest a simple synthesis model of an eclipsing binary system which includes one component with strong stellar wind. Numerical simulations show that the shape of the light curve (and in particularly the widths of the minima) strongly depends on wind parameters. Wind effects are crucial in modelling light curves of binaries including e.g., WR stars.
