Results of radial velocity measurements from our spectrograms and orbital elements with elliptical orbit computed from them and published data are presented. It is suggested that light variations could be explained widths of some lines are interpreted by rotation.
Radial velocities of H2 - H9 abd Ca II K lines on 27 high dispersion (0.27 nm/mm) spectrograms of the HgMn-star Alpha Andromedae were measured, While radial velocities of Balmer lines show no significant changes, radial velocities of Ca II K line vary in the limits from 5 to 13 km/s. A frequency analysis of the Ca II K RV values leads to two different frequencies of 27.86 and 35.20 c/d. Their superposition results is a 196 min beat-phenomenon period. Halfwidth of the calcium line varies in the way which could be explained by nonradial oscillations.
