  Central compact objects (CCOs) are neutron stars that are found near the
center of supernova remnants, and their association with supernova remnants
indicates these neutron stars are young (<~ 10^4 yr). Here we review the
observational properties of CCOs and discuss implications, especially their
inferred magnetic fields. X-ray timing and spectral measurements suggest CCOs
have relatively weak surface magnetic fields (~ 10^10 - 10^11 G). We argue
that, rather than being created with intrinsically weak fields, CCOs are born
with strong fields and we are only seeing a weak surface field that is
transitory and evolving. This could imply that CCOs are one manifestation in a
unified picture of neutron stars.
