Corotating light cylinders and Alfv\'en waves

Abstract

Exact relativistic force free fields with cylindrical symmetry are explored. Such fields are generated in the interstellar gas via their connection to pulsar magnetospheres both inside and outside their light cylinders. The possibility of much enhanced interstellar fields wound on cylinders of Solar system dimensions is discussed but these are most likely unstable.Comment: 6 pages, 6 figures, accepted by MNRA
