Radial and rotational velocities for a sample of magnetic CP stars

Radial and rotational velocities for a sample of magnetic CP stars The spectra taken with the Main Stellar Spectrograph (MSS) of the 6-m telescope with a resolution of R ∼ 15000 and a signal-to-noise ratio of 200–300 are used to determine the radial velocities and projected rotational velocities (υ e sin i) for 32 magnetic CP stars. Measured υ e sin i values range from 18 km/s (the lower boundary determined by the instrumental profile) to 65 km/s. Measurements of standard stars demonstrate the absence of systematic differences between our and published data. Eight of the 32 magnetic stars are found or confirmed to be binary and binarity is suspected for another four stars. The components of tangential velocity are determined for 27 stars with known parallaxes. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Astrophysical Bulletin Springer Journals

Abstract

The spectra taken with the Main Stellar Spectrograph (MSS) of the 6-m telescope with a resolution of R ∼ 15000 and a signal-to-noise ratio of 200–300 are used to determine the radial velocities and projected rotational velocities (υ e sin i) for 32 magnetic CP stars. Measured υ e sin i values range from 18 km/s (the lower boundary determined by the instrumental profile) to 65 km/s. Measurements of standard stars demonstrate the absence of systematic differences between our and published data. Eight of the 32 magnetic stars are found or confirmed to be binary and binarity is suspected for another four stars. The components of tangential velocity are determined for 27 stars with known parallaxes.
