Characteristics of energetic pulsars

DOI

In this paper we compare the characteristics of pulsars with a high spin-down energy loss rate (Edot) against those with a low Edot. We show that the differences in the total intensity pulse morphology between the two classes are in general rather subtle. A much more significant difference is the fractional polarization which is very high for high Edot pulsars and low for low Edot pulsars. The Edot at the transition is very similar to the death line predicted for curvature radiation. This suggests a possible link between high energy and radio emission in pulsars and could imply that gamma-ray efficiency is correlated with the degree of linear polarization in the radio band. As part of this study, we have discovered three previous unknown interpulse pulsars (and we detected one for the first time at 20cm). We also obtained rotation measures for 18 pulsars whose values had not previously been measured.
