Detection of a Debris Disk around an AXP with Spitzer

Abstract:
We have detected of a debris disk around a young isolated neutron star
(specifically, an AXP) using Spitzer data. There is a clear signature
of thermal emission from a disk in the mid-IR (it is a completely
distinct spectral component from the optical emission), and it is
well-fit by an X-ray heated disk model (a passive, irradiated debris
disk, not an accretion disk). This may well be the first detection of
a supernova fallback disk.
