| Abstract: | We present spectroscopic CCD observations of R Canis Majoris obtained in 1993. A total of 19 plates for Hα line were secured
and reduced with the IRAF for radial velocities. A new radial velocity curve has been analyzed with collected light curves
by the method of the Wilson and Devinney Differential Correction. The solution set including mass ratio q = 0.17 is determined
as a unique solution by cross checking simultaneous adjustment of radial velocity and light curves, mass-luminosity relation,
and distance.
This revised version was published online in July 2006 with corrections to the Cover Date. |
