The Radcliffe Wave is not alone in the Local System

Abstract
The spatial distribution of open star clusters (OSCs) younger than 30 million years old in the Local System was studied. It was shown for the first time that a significant number of OSCs belong to the recently discovered Vela Ridge gas and dust supercloud. The most intriguing property of this sample of OSCs is the presence of periodic perturbations in their vertical coordinates with a maximum amplitude of 47 pc and a wavelength of 1.1 kpc. Thus, the discovered chain of young OSCs is analogous to the Radcliffe Wave, but with a lower amplitude of vertical perturbations, a shorter wavelength, and is, on average, 2 million years older.
