五条半路形成毫秒脉冲星

Five and a half roads to form a millisecond pulsar

Thomas M. Tauris

摘要:

在这篇综述中,我讨论的特点和形成的所有类别的毫秒脉冲(MSP)。主要重点是X射线双星的恒星天体物理学,导致生产完全回收的MSP与白矮星(WD)或亚恒星半简并同伴。根据伴星的性质,MSP被认为是由低质量X射线双星(LMXB)或中等质量X射线双星(IMXB)形成的。对于这两类X射线双星的演化状态的捐助者的明星-或相当于,轨道周期-在罗奇叶溢出(RLO)的发病是决定性因素的质量转移阶段的结果,从而形成的MSP的性质。此外,形成的二进制MSP的(P,P_点)图的上下文中进行了讨论,以及新的解释的Corbet图。最后,我提出了新的模型,以再现两个太阳质量脉冲星PSR J1614-2230的IMXB的情况A RLO。

英文摘要:

In this review I discuss the characteristics and the formation of all classes of millisecond pulsars (MSPs). The main focus is on the stellar astrophysics of X-ray binaries leading to the production of fully recycled MSPs with white dwarf (WD) or substellar semi-degenerate companions. Depending on the nature of the companion star MSPs are believed to form from either low-mass X-ray binaries (LMXBs) or intermediate-mass X-ray binaries (IMXBs). For each of these two classes of X-ray binaries the evolutionary status of the donor star -- or equivalently, the orbital period -- at the onset of the Roche-lobe overflow (RLO) is the determining factor for the outcome of the mass-transfer phase and thus the nature of the MSP formed. Furthermore, the formation of binary MSPs is discussed in context of the (P,P_dot)-diagram, as well as new interpretations of the Corbet diagram. Finally, I present new models of Case A RLO of IMXBs in order to reproduce the two solar mass pulsar PSR J1614-2230.
