毫秒双星的吸积质量和最小磁场问题

Questions on accreting mass and minimum magnetic field of millisecond pulsars

C. M. Zhang

摘要:

在双星吸积阶段,毫秒脉冲星(MSP)吸收了大约0.2太阳质量的磁场,而MSP的极向磁场被稀释到108.5高斯量级,这与质量吸积速率成正比。发现当吸积速率达到最小值1015 g/s时,MSP的最小磁场可低至107 Gauss。这个底部字段与MSP初始字段无关。提出并回答了有关MPPS的一些问题。

英文摘要:

About 0.2 solar mass is absorbed by the millisecond pulsar (MSP) at the binary accretion phase, while the polar magnetic field of MSP is diluted to a magnitude of order 108.5 Gauss, which is proportionally related to the mass accretion rate. It is found that the minimum magnetic field of MSP can be as low as 107 Gauss if the accretion rate of the binary system reaches its the minimum value of 1015 g/s. This bottom field has nothing to do with the MSP initial field. Some questions on MPSs are proposed and answered.
