The High Energy X-ray Probe (HEX-P): Pulsar Monitoring, Timing and Searches using Broadband X-ray Emission

HEX-P is a probe-class mission concept that will combine high spatial resolution X-ray imaging (<10 arcsec FWHM) and broad spectral coverage (0.1-150 keV) with an effective area far superior to current facilities (including XMM-Newton and NuSTAR), to enable revolutionary new insights into a variety of important astrophysical problems. We will present simulations of HEX-P’s ability of timing pulsars over a range of luminosity and spin ranges. We simulate HEX-P’s ability to detect pulsed emission over a broad energy range and explore its ability to provide a robust timing solution for pulsars over a range of spin periods. HEX-P would allow us to probe spin evolution, and find new pulsar systems especially in crowded environments. HEX-P will also enable the study of geometry and energetics of intra-binary shocks in pulsar binaries allowing for a deeper understanding of particle acceleration, companion ablation and orbital evolution of pulsar binaries.
