脉冲星PSR J0737-3039A转动惯量测量的展望
Prospects for measuring the moment of inertia of pulsar PSR J0737-3039A
摘要:
在这里,我们考虑的可能性,测量在10%或更好的转动惯量I的J 0737 - 3039 A通过重力磁自旋轨道近星点进动。事实证明,考虑到通过无线电定时测量系统基本二进制和后开普勒参数的精度限制,以10%或更高精度测量PSR J 0737 - 3039 A的转动惯量的前景似乎不太可能。
英文摘要:
Here we consider the possibility of measuring at 10% or better the moment of inertia I of the J0737-3039A via the gravitomagnetic spin-orbit periastron precession. It turns out that the prospect of measuring the moment of inertia of PSR J0737-3039A at 10% accuracy or better seems unlikely given the limitations to the precision with which the system's basic binary and post-Keplerian parameters can be measured via radio timing.
