radial velocity

基本解释

Just to be sure, the team followed up with six radial velocity observations at the Keck I telescope in Hawaii.
为了证实这一观点，该小组使用位于夏维夷的凯克一号望远镜，进行了六个径向速度观测。
The new planets were detected by measuring “radial velocity, ” or how fast a star wobbles depending on the gravitational pull from nearby planets.
新的行星是靠测量“径向速度”，或者恒星在周围行星的万有引力下摇摆的速度检测出来的。
Radial velocity, also known as the Doppler wobble technique, involves searching for wobbles in a star's light that indicate the gravitational pull of an orbiting planet.
径向速度法，也被称为多普勒摆动技术，用于搜索恒星光线的摆动，它显示出来自轨道上运行的行星的万有引力。

The science news headlines are buzzing today with the results of a new study by astronomers from the High Accuracy Radial velocity Planet Searcher (HARPS).

An instrument called HARPS (short for High Accuracy Radial velocity Planet Searcher) is also a top contender, having already spotted a number of potentially habitable worlds.

By using an entirely different planet-hunting approach, it should be able to plug this gap, and provide a means of calibrating the census figures resulting from the radial-velocity and astrometric searches.
