A comprehensive analysis of previously published observations of Algol has been submitted to Astronomy&Astrophysics under the title “Geometry and Dynamics of the Algol System”. The main results can be summarized as follows:

The masses of the three components are mA = 3.6±0.1, mB=0.79±0.01, mC=1.6±0.1 solar masses.

The orbit of Algol C is co-planar with the AB-orbit within some 3°, but polarimetry of the eclipsing pair indicates that the senses of revolution are opposite.

The close orbit is circular, thus the 32 year period in the times of minima can not be explained by apsidal motion.
