Abstract

We investigate the prospects for experimentally determining the Sun’s angular momentum by measuring the gravitomagnetic frequency shift of signals exchanged by two satellites in heliocentric orbits. When using modern optical clocks with stability of ∼10^–18, the accuracy of such an experiment can reach 5% after 5 years of data accumulation. This is comparable to the accuracy of determining the Sun’s angular momentum using techniques of helioseismology.

利用重磁频移效应测量太阳的角动量

摘要

我们研究了通过测量日心轨道上两颗卫星交换的信号的重磁频移来实验确定太阳角动量的前景。当使用稳定性为∼10 ^–18的现代光钟时，经过5年的数据积累，这样的实验的精度可以达到5%。这与使用日震学技术确定太阳角动量的精度相当。
