| Abstract: | We present observations and light curve analysis of the eclipsing binary R CMa in the narrow band filters v and b. Observations were made during 1993 at Biruni Observatory and the light curves have been analyzed using the Wilson-Devinney
light curve interpretation program. Assuming a semi-detached configuration for R CMa, the parameters i, Ω1, L
1, T
2 and A
2 were adjusted for the best fit between the synthesized light curves and observations. Both light curves were fitted well
with a lower value of bolometric albedo than what would be expected for a normal cool star with a convective envelope. The
masses of the primary and secondary components and the absolute dimensions of the stars have been calculated using the derived
relative dimensions from Wilson-Devinney codes and the spectroscopic observations. |
