The paper discusses various stellar parameters and the ultimate fate of the binary star system CW Canis Major. Using observational data of the radial velocities and apparent visual magnitudes the individual masses and radii have been determined. These values have allowed us to estimate the spectral classification of the stars.

Zusammenfassung der Kapitel (Chapter Summaries)
I. INTRODUCTION
This chapter provides an overview of the historical context of binary star systems, highlighting their importance in understanding the universality of Newton's law of gravitation. It introduces CW Canis Majoris, an eclipsing binary system that will be the focus of the study. The chapter discusses the methods and data sources used for analyzing the system, including light curve data from the All Sky Automated Survey (ASAS) and radial velocity data from the McDonald Observatory.
II. ANALYSIS OF LIGHT CURVE AND RADIAL VELOCITY MEASUREMENTS
This chapter delves into the analysis of the light curve and radial velocity data for CW Canis Majoris. It utilizes basic assumptions, such as a total primary eclipse and an inclination angle of 90°, to calculate the visual magnitudes and radial velocities of both stars. By analyzing these data, the chapter derives the mass ratio of the system and estimates the semi-major axes of the individual stars.
