Abstract:
We present the results of measuring longitudinal magnetic fields
(Be), rotation velocities (vesini), and radial velocities (Vr)
of 92 stars observed with the Main Stellar Spectrograph (MSS) of the
6-m BTA telescope of the Special Astrophysical Observatory in 2010.
Observations of standard stars without magnetic fields confirm the
absence of systematic errors capable of introducing distortions into
the longitudinal-field measurement results.
Description:
Data was obtained at the Main Stellar Spectrograph of the Russian 6-m
telescope during 2010. We got 195 zeeman spectra for 92 stars.
