Query: An X-ray View of Radio Millisecond Pulsars   In recent years, X-ray observations with Chandra and XMM-Newton have
significantly increased our understanding of rotation-powered (radio)
millisecond pulsars (MSPs). Deep Chandra studies of several globular clusters
have detected X-ray counterparts to a host of MSPs, including 19 in 47 Tuc
alone. These surveys have revealed that most MSPs exhibit thermal emission from
their heated magnetic polar caps. Realistic models of this thermal X-ray
emission have provided important insight into the basic physics of pulsars and
neutron stars. In addition, intrabinary shock X-ray radiation observed in
``black-widow'' and peculiar globular cluster ``exchanged'' binary MSPs give
interesting insight into MSP winds and relativistic shock. Thus, the X-ray band
contains valuable information regarding the basic properties of MSPs that are
not accesible by radio timing observations.
