Some Developments of the Weak Stellar Magnetic Field Determination Method for the Example of Cygnus X-1
Abstract
Some developments of measurements of the weak stellar magnetic fields by the least square technique applied to spectropolarimetric data are proposed and used for the X-ray binary Cyg X-1 = HDE 226868 (the optical counterpart is an O 9.7 supergiant).
