Q:  Assume that both stars in CV Vel move in
      perfect circles.  What is the orbital
      radius R for each star?  Express your
      value in AU.

                              (period) * (velocity)
        orbital radius R  =  ----------------------
                                  2 * pi

                              (595,210 s) * (133,000 m/s)
                          =  ----------------------------
                                    2 * pi


                          =   1.27 x 10^(10) m

                          =   0.0845 AU


  Q:  What is the separation between the two stars?
      This serves as the semi-major axis "a" in Kepler's
      Third Law when the two objects are comparable
      in mass to each other.


          separation  a   =  2 * R

                          =  0.169 AU


  Q:  What is the total mass of the CV Vel system?


                                                    3
                             (semi-major axis in AU)
    total mass (solar)   =  -------------------------
                                                 2
                                (Period in years)


                              (0.169 AU)^3
                         =   ----------------   =   13.5 solar masses
                              (0.0189 year)^2
