# Gould Belt Members in X-ray RAVE: Cross-Matching RAVE Stars with 3XMM Point Sources

## TL;DR

This study cross-matched RAVE spectroscopic data with XMM-Newton X-ray sources to identify potential Gould Belt members, resulting in a catalog of 1071 stars with 10 probable Gould Belt members, including variable and cluster stars.

## Contribution

It presents the first combined X-ray and spectroscopic catalog of RAVE stars and identifies potential Gould Belt members using photometric and kinematic criteria.

## Key findings

- Identified 10 Gould Belt member candidates among 1071 stars.
- Members exhibit low velocity dispersions, suggesting a common structure.
- Kinematic tests for Gould Belt membership may be feasible with larger samples.

## Abstract

In this paper the results of matching the RAdial Velocity Experiment (RAVE), a spectroscopic Southern hemisphere survey (9 $ < I_{DENIS} <$ 12), and XMM-Newton Serendipitous Source Catalogue (3XMM) are presented. The latest data releases of RAVE and XMM were matched and a X-ray RAVE catalogue of 1071 stars was obtained. Then the catalogue was checked for possible Gould Belt (GB) members. We obtained a subsample of 10 stars that meet the GB membership criteria. This subsample and GB member candidates were tested photometrically and kinematically. Among the members there are two BY Dra type variables, an NGC2451 open cluster member, a high proper motion star. The rest are regular main sequence stars. The members have very low velocity dispersions which lead us to think that the members belong in a single structure. We also found out that a kinematical GB membership test might be possible to derive given a large enough GB member sample as they fit in a narrow interval in space velocity diagrams.
