Interstellar polarization at high galactic latitudes from distant stars. V. First results for the South Galactic Pole
We present the first results of our interstellar polarization programmefor the South Galactic Pole (b<-70degr ). The new observations (43stars) combined with previously published data show that there is asubstantial interstellar polarization in this area of the sky. Startingat a distance of 300 pc, we have found stars with P > 0.3% includingone for which P ~ 0.6%. These measurements lead to the conclusion thatthere is a significant amount of interstellar dust at high southgalactic latitudes. Futhermore, there is a remarkable alignment seenover the South Polar Cap: for most stars the directions of polarizationvectors are aligned with the longitude l ~ 80degr , close to theexpected direction of the global magnetic field. In this respect the SGPseems to differ strongly from its northern counterpart.

Velocities of rotation of chemically peculiar stars
An analysis of the velocities of rotation of 77 peculiar stars, membersof open clusters and associations in the age range log t = 6.4-8.7, wasmade based on observations with the OZSP spectrograph of the 6-mtelescope. It was concluded that there is no loss of angular momentum bypeculiar stars in the process of gravitational contraction as theyapproach the zero-age main sequence and in the stage of evolution withinthe main sequence. A statistically significant difference was obtainedin the velocities of rotation of peculiar stars in different zones ofthe Scorpio-Centaurus association: Stars of the core (t = 4 million yr)rotate faster on the average than stars in the outer zones of theassociation (t = 12 million yr).
