二进制和毫秒脉冲星

Binary and Millisecond Pulsars

D. R. Lorimer

摘要:

本文综述了射电双星和毫秒射电双星的主要特性、人口统计和应用。近年来,我们对这些令人兴奋的天体的了解大大增加,主要是由于成功的调查使已知的脉冲星数量超过1800。现在有83个双星和毫秒双星与我们银河系的圆盘有关,另外还有140个双星在银河系的26个球状星团中。最近的亮点包括发现了年轻的相对论双星系统PSR J 1906 +0746,这是球状星团脉冲星研究中的一次复兴,包括越来越多的质量超过1.5个太阳质量的球状星团,精确测量了双脉冲星系统中的相对论自旋进动,以及一颗银河系毫秒脉冲星在一个未演化的伴星的偏心轨道上(e=0.44)。

英文摘要:

We review the main properties, demographics and applications of binary and millisecond radio pulsars. Our knowledge of these exciting objects has greatly increased in recent years, mainly due to successful surveys which have brought the known pulsar population to over 1800. There are now 83 binary and millisecond pulsars associated with the disk of our Galaxy, and a further 140 pulsars in 26 of the Galactic globular clusters. Recent highlights include the discovery of the young relativistic binary system PSR J1906+0746, a rejuvination in globular cluster pulsar research including growing numbers of pulsars with masses in excess of 1.5 solar masses, a precise measurement of relativistic spin precession in the double pulsar system and a Galactic millisecond pulsar in an eccentric (e=0.44) orbit around an unevolved companion.
