High-magnetic-field pulsars represent an important class of objects for studying the relationship between magnetars and radio pulsars .
Here we report on four Chandra observations of the high-magnetic-field pulsar J1718 - 3718 ( B = 7.4 \times 10 ^ { 13 } G ) taken in 2009 as well as on a re-analysis of 2002 Chandra observations of the region .
We also report an improved radio position for this pulsar based on ATCA observations .
We detect X-ray pulsations at the pulsar ’ s period in the 2009 data , with pulsed fraction 52 % \pm 13 % in the 0.8–2.0 keV band .
We find that the X-ray pulse is aligned with the radio pulse .
The data from 2002 and 2009 show consistent spectra and fluxes ; a merged overall spectrum is well fit by a blackbody of temperature 186 ^ { +19 } _ { -18 } eV , slightly higher than predicted by standard cooling models , however , the best-fit neutron star atmosphere model is consistent with standard cooling .
We find the bolometric luminosity L ^ { \infty } _ { bb } = 4 ^ { +5 } _ { -2 } \times 10 ^ { 32 } erg s ^ { -1 } \sim 0.3 \dot { E } , for a distance of 4.5 kpc .
We compile measurements of the temperatures of all X-ray detected high- B pulsars as well as those of low- B radio pulsars and find evidence for the former being on average hotter than the latter .
