Contribution

It introduces a novel mechanism where gluon vortices in color superconductors induce magnetic fields in compact stars.

Findings

Color superconductivity can naturally produce magnetic fields in stellar cores.

Gluon vortices contribute to magnetic field generation.

The mechanism explains strong magnetic fields in magnetars.

Abstract

The natural candidates for the realization of color superconductivity are the extremely dense cores of compact stars, many of which have very large magnetic fields, especially the so-called magnetars. In this paper we discuss how a color superconducting core can serve to generate and enhance the stellar magnetic field without appealing to a magnetohydrodynamic dynamo mechanism.
