The Radcliffe wave parameters from data on open star clusters

Abstract

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, 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 degrees 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 $Z_{max}=92\pm 10$ pc with the wavelength of these perturbations ${\lambda }_z=4.82\pm 0.09$ kpc; b)~maximum value of the velocity of vertical disturbances $W_{max}=4.36\pm 0.12$ km s${}^{-1}$ with disturbance wavelength ${\lambda }_W=1.78\pm 0.02$ kpc. Note that the results of the vertical velocity analysis are first-class in accuracy and completely new.
