Unique Solution of R Canis Majoris
Source: Astrophysics and Space Science, Volume 259, Number 4, 1998 , pp. 403-413(11)
We present spectroscopic CCD observations of R Canis Majoris obtained in 1993. A total of 19 plates for H 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.
