Abstract Analysis of observational data of OB stars show an, excellent agreement of the density distributions in space ϱ(x, y, z) as well as in velocity space $$\rho (\dot x,\dot y,\dot z)$$ with the predictions of the density wave theory, the values for the density and velocity fluctuations are explained only by the non-linear theory. These theoretical calculations predict perturbations greater than ±10 km s−1, consistent with the observations for the velocity field. Thus one should disregard analytical treatments of the linearized equations since they predict maximum perturbations of ±5km s−1. Another consequence of this is the fact that the Gould's Belt is not a local anomaly, but a local feature of the density waves. The analysis of observational data show that the wave pattern is similar to that of the gas and dust.
