Pulsars old and close in space: Hot polar-caps or magnetospheric emission

We have made a program to study the Xray emission properties of old and close by pulsars in order to probe and identify the origin of their X radiation. These pulsars, being intermediate from its age between the young cooling neutron stars and the old millisecond pulsars, are of special interest in order to understand the Xray emission properties of rotationpowered pulsars in its whole. For all proposed objects we will obtain spectral and temporal information in a moderate amount of observing time allowing to discriminate between thermal and nonthermal emission processes. This task can only be investigated by a combined spectral and truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
