Phase space analysis of the young stellar component of the Radcliffe Wave
Abstract
The Radcliffe Wave is a galactic-scale structure recently proposed by J. Alves et al. (2019). The authors propose that various molecular complexes in the solar environment follow a specific alignment and displacement that make them worthy of a common origin and evolution. In this work, we first collected and analyzed the population of very young stars and open clusters around this structure. The criteria for cross-matching these star-forming tracers with the identified Radcliffe Wave cloud complexes have been defined and applied, all based on the quality of the available astrometric and photometric data. We performed a first characterization of the structure and kinematic properties of the young stellar population linked to this wave. Our conclusions, although verypreliminary, are: 1) we have identified 13 open clusters, each of them physically linked to a Cloud Complex, which are probable members of the Radcliffe Wave; 2) The OB field stars do not present the elongated structure that departs from an straight line at the Sun position observed in the Cloud Complexes; 3) the vertical motion of 11 CC-OCs members associated with the Wave is not contradictory with the behaviour expected from a simple model of harmonic motion in the vertical direction, and 4) the orbits back on time neither suggest an origin associated to a point nor to a straight line in the XZ plane.
