The Radcliffe wave parameters from data on open star clusters
arXiv:2401.02144 · doi:10.1088/1674-4527/ad113f
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 pc with the wavelength of these perturbations kpc; b)~maximum value of the velocity of vertical disturbances km s with disturbance wavelength kpc. Note that the results of the vertical velocity analysis are first-class in accuracy and completely new.
