Abstract:
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.
