Abstract:
We present the results of the magnetic field measurements of 37
chemically peculiar and 4 normal main sequence stars using circularly
polarized spectra obtained in 2008 with a Zeeman analyzer on the Main
Stellar Spectrograph (MSS) of the Russian 6-m telescope (BTA). Four
new magnetic stars have been discovered (HD25999, HD35100, HD96237,
and HD279021), the presence of a field was suspected in two stars
(HD2887 and BD-12 2366), 16 previously known CP stars were continued
to be monitored to study their fields. The results of the longitudinal
magnetic field Be measurements show that in stars with narrow
spectral lines, systematic errors in Be determination do not exceed
10-20G, which is within the statistical error. Our study of stars with
reliable phase curves of the longitudinal field Be show that there
are no instrumental effects which can distort the observations.
Description:
Data was obtained at the Main Stellar Spectrograph of the Russian 6-m
telescope during 2008. We got 92 zeeman spectra for 37 CP stars and 4
normal stars.
