Possible new binaries among the Wolf-Rayet stars
Spectra of Wolf-Rayet stars HD 92740 and HD 93131, obtained between May 16 - May 23, 1970, at Cerro Tololo Intermaerican Observatory, in Chile, confirm that these stars show the superior members of the Balmer series in absorption. The radial velocities of various emission lines measured indicate var...

| Sumario: | Spectra of Wolf-Rayet stars HD 92740 and HD 93131, obtained between May 16 - May 23, 1970, at Cerro Tololo Intermaerican Observatory, in Chile, confirm that these stars show the superior members of the Balmer series in absorption. The radial velocities of various emission lines measured indicate variations of the order of 140 km/s for HD 92740 and of the order of 180 km/s for HD 93131. These stars may be binaries with periods of the order of a month. |
