A SPECTROGRAPHIC ORBIT FOR THE ECLIPSING BINARY V757 CENTAURI

Twenty-two spectrograms obtained at the Cerro Tololo Inter-American Observatory, Chile, have been used to determine, for the first time, the spectrographic orbital elements of the eclipsing binary V757 Cen. Both components of the binary system are of the spectral type about GO V, and the physical pa...

Zusammenfassung:Twenty-two spectrograms obtained at the Cerro Tololo Inter-American Observatory, Chile, have been used to determine, for the first time, the spectrographic orbital elements of the eclipsing binary V757 Cen. Both components of the binary system are of the spectral type about GO V, and the physical parameters are found to be similar to the other W UMa binaries.
