TL;DR
This study maps the distribution of X-ray sources in Orion to understand the star formation history near the Gould Belt, providing insights into young stellar populations in the region.
Contribution
It presents the first large-scale analysis of ROSAT X-ray sources in Orion, linking X-ray emission to young stars and star formation processes.
Findings
Distribution of X-ray sources correlates with young stellar populations
Identifies large-scale structures associated with star formation
Provides data for future star formation history studies
Abstract
We report first results on the large-scale distribution of the ROSAT All-Sky Survey (RASS) X-ray sources in a 5000 deg^2 field centered on Orion. Our final aim is to study the properties of different widespread populations in the Orion Complex close to the Gould Belt (GB) in order to trace the star formation history in the solar neighbourhood.
