Abstract
We present high resolution spectra of the pulsars PSR B0656+14
and 4U 0142+61 using the Chandra grating spectrometers.
Both pulsars have estimated magnetic fields in excess of 1012G and have no clearly associated supernova remnants. The pulsar
4U 0142+61 is often cited as an example of an ``anomalous X-ray
pulsar'' with a significantly larger magnetic field. The broad-band
spectra require a steep power law component to explain the high
energy data while the spectral peaks appear to be dominated by
a thermal component with a observed temperatures of
K for PSR B0656+14 and
K
for 4U 0142+61. We present pulse-phased spectra and results
from a detailed search for spectral features.
