Query: Pulsars With Jets May Harbor Dynamically Important Accretion Disks   For many astrophysical sources with jets, there is evidence for the
contemporaneous presence of disks. In contrast, pulsars such as the Crab and
Vela show jets but have not yet revealed direct evidence for accretion disks.
Here we show that for such pulsars, an accretion disk radiating below
detectable thresholds may simultaneously account for (1) observed deviations in
the braking indices from that of the simple dipole, (2) observed pulsar timing
ages, and (3) possibly even the jet morphology via a disk outflow that
interacts with the pulsar wind within, collimating and/or redirecting it.
