Magnetic fields in hot subdwarfs.
Abstract
We present new longitudinal magnetic field measurements of two hot subdwarfs. From circularly polarized spectra obtained at the 6-metre telescope we infer magnetic fields of B_e_=-1680+/-60G in the sdO subdwarf BD+75 325 and a variable field in the sdOB subdwarf BD+25 2534, with extrema of -1300G and +1750G.
