| Abstract: |
We review the high-energy emission properties of black widow and red-back pulsar binaries, which consist of a millisecond pulsar and a low-mass companion. In these systems, the interaction between the pulsar wind and the companion’s wind (or magnetic field) generates diverse high-energy phenomena. These phenomena offer valuable insights into relativistic shocks in astrophysical environments. Pulsar-binary systems are particularly valuable for studying wind-wind interaction and shocked flow because the nature of the companion and the millisecond pulsar are well-understood. Additionally, the circular orbits eliminate complications arising from varying distances between the emission components, and the absence of accretion from the companion allows for a clear identification of the emissions from the pulsar, the companion, and the intrabinary shock. Modeling these emissions has significantly advanced our knowledge of pulsar binaries. In this paper, we review the high-energy aspects of pulsar binaries and discuss the outstanding questions that require further investigation. |
