摘要

简要介绍了近几年来裸奇异星研究的一些重要进展，包括裸奇异星表面的电学性质和辐射机制，夸克表面存在的一些可能天体物理后果(如射电脉冲星的漂移子脉冲现象和软g射线重复源的超Eddington辐射现象)等。这些研究结果对从天文观测上区分中子星和奇异星、证认奇异星的存在具有重要意义。

Abstract

Recent progress in the study of bare strange stars is briefly reviewed. Discussions of the electric characters and the emission mechanisms of bare quark surface, and of the possible astrophysical implications of the existence of bare strange stars, e.g., the drifting sub-pulse phenomenon of radio pulsars and the super-Eddington emission of soft gammaray repeaters, are presented. These researches are essential to distinguish neutron stars and (bare) strange stars in astrophysics.
