Special Session SS11  27 June 2022

The astonishing variety of neutron star neighbourhoods

Aims and scope

The neighbourhood of a neutron star shows a rich observational phenomenology and provides a laboratory of various topics in astrophysics such as shock physics, high energy particle acceleration and propagation, or interactions of matter with radiation and magnetic fields. New observational diagnostics of this local environment are enabled by the powerful emission of the neutron star, its explosive birth, and relativistic outflows. These diagnostics also reveal important puzzle pieces in the story about the past, present and future properties and evolution of the compact object.

Existing and future observing facilities provide or will provide a wealth of multiwavelength data, accompanied by cutting edge theoretical modelling. Join us in this session to share and review the research highlights, discuss the open questions on neutron star environments, and catalyse ideas how to solve these questions.


This session will focus on neutron stars without stellar companions.

  • Compact Objects in Core-Collapse Supernova Remnants **
  • Pulsar Wind Nebulae
  • TeV Halos
  • Disks around Neutron Stars
  • Planets and Asteroids around Neutron Stars
** Note that the physics of supernova remnants is topic of Special Session 17.
