The Radcliffe Wave Parameters from Data on Open Star Clusters

V. V. Bobylev and A. T. Bajkova


A spectral analysis of the vertical positions and velocities of 374 open star clusters (OSCs) was carried out. We took these OSCs from the Hunt and Reffert catalog; they have an average age of about 10 million years, and are located on the galactic plane XY in a narrow zone inclined by 25° to the galactic axis Y. The following estimates of the parameters of the Radcliffe wave were obtained: (a) the maximum value in periodic perturbations of vertical coordinates pc with the wavelength of these perturbations λz = 4.82 ± 0.09 kpc; (b) the maximum value of the velocity of vertical disturbanceskm s−1 with disturbance wavelength λW = 1.78 ± 0.02 kpc. Note that the results of the vertical velocity analysis are first-class in accuracy and completely new.
