Determination of Wind Parameters by the Method of Differential Corrections
This paper describes a method for the determination of wind parameters as mass-loss rate, wind velocity, stochastic velocity in Zeta Aurigae type binaries. We have modified the Baade's (1989) computer code to analyze the wind parameters of Zeta Aurigae type binaries according to the least squar...

| description | This paper describes a method for the determination of wind parameters as mass-loss rate, wind velocity, stochastic velocity in Zeta Aurigae type binaries. We have modified the Baade's (1989) computer code to analyze the wind parameters of Zeta Aurigae type binaries according to the least squares criterion. The modified program adjusts the wind parameters by the method of differential corrections. We have applied this method to the IUE observations of 32 Cygni. We have fitted a theoretical line profile to the IUE observations of Fe II resonance line at various phases. The mass-loss rate, wind velocity and stochastic velocity of 32 Cygni obtained in this paper are 2.18 x 10^-8M_solar/yr, 132.14km/s, 39.82km/s, respectively. |
