Velocity curve analysis of spectroscopic binary stars EQ Tau, V376 And, V776 Cas, V2377 Oph and V380 Cygni by nonlinear regression
Using measured radial velocity data of five double-lined spectroscopic binary systems EQ Tau, V376 And, V776 Cas, V2377 Oph and V380 Cygni, we find corresponding orbital and spectroscopic elements via the method introduced by Karami & Teimoorinia and Karami & Mohebi. Our numerical re...

| description | Using measured radial velocity data of five double-lined spectroscopic binary systems EQ Tau, V376 And, V776 Cas, V2377 Oph and V380 Cygni, we find corresponding orbital and spectroscopic elements via the method introduced by Karami & Teimoorinia and Karami & Mohebi. Our numerical results are in good agreement with those obtained by others using more traditional methods. |
