ABSTRACT
The radio pulsar B1951+32 and the supernova remnant CTB 80 provide a
rich laboratory for the study of neutron stars and supernova remnants. Here, we
present ground-based optical and near-infrared observations of them, along with
X-ray observations with Chandra and a re-analysis of archival data obtained with
the Hubble Space Telescope. The X-ray observations reveal a cometary pulsar
wind nebula which appears to be confined by a bow shock produced by high-
velocity motion of the pulsar, making PSR B1951+32 a rare pulsar exhibiting
both an Hα bow shock and a shocked X-ray pulsar wind nebula. The distribution
of Hα and radio continuum emission is indicative of a contact discontinuity of the
shocked pulsar winds and shocked ambient medium at ～0.05 pc. On the other
hand, the optical synchrotron knot of PSR B1951+32 likely has a flat spectrum
in the optical and near-infrared wavebands, and our astrometry is consistent with
only one of the two reported optical counterpart candidates for the pulsar.
