A high-magnetic-field radio pulsar survey with Swift/XRT

Abstract

We present the X-ray survey results of high-magnetic-field radio pulsars (high-B PSRs) with Swift/XRT. X-ray observations of the rotation-powered pulsars with the dipole magnetic field $B_{\mathrm{d}}$ near the quantum critical field $B_{\mathrm{q}}=4.4\times 10^{13}$ G is of great importance for understanding the transition between the rotation-powered pulsars and the magnetars, because there are a few objects that have magnetar-like properties. Out of the 27 high-B PSRs that are in the ATNF pulsar catalogue but have not been reported or have no effective upper-limits in the X-ray bands, we analyze the Swift/XRT data for 21 objects, where 6 objects are newly observed and 15 objects are taken from the archival data. As a result, we have new $3\sigma$ upper-limits for all the 21 objects. Since the upper-limits are tight, we conclude that we do not find any magnetar-like high-B PSRs such as PSR J1819$-$1458. The probability of the high X-ray efficiency in the high-B PSRs is obtained to be $11\%-29\%$. Combining the previous observations, we discuss which parameter causes magnetar-like properties. It may be suggested that the magnetar-like properties appear only when $B_{\mathrm{d}}\gtrsim 10^{13.5}$ G for the radio pulsar population. This is true even if the radio-quiet high-B RPP are included.
