Kapteyn's star spectroscopic measurements

Exoplanets of a few Earth masses can be now detected around nearby low-mass stars using Doppler spectroscopy. In this paper, we investigate the radial velocity variations of...目前，利用多普勒光谱学（Doppler spectroscopy）技术，可在邻近低质量恒星周围探测到质量为数个地球质量的系外行星。本文针对径向速度变化展开探究……
