Pulsars With Jets May Harbor Dynamically Important Accretion Disks

Astrophysics 2009-11-10 v1

Abstract

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.
