Scientific paper

We have used the database of X-ray sources detected in the ROSAT PSPC pointed observations to search for active late-type stars associated with the Gould Belt. Our cross-correlation with the Tycho-2 catalogue shows an enhancement of X-ray sources positionally coincident with the Gould Belt. Compared to an other study based on the ROSAT all-sky survey we find a substantially larger stellar surface density at the position of the Gould Belt, which is consistent with the higher sensitivity of this data. Furthermore, we find an anticorrelation of longitudinal stellar surface density with intervening ISM.
