But in recent years astronomers have used radial velocity to find or confirm a number of planets down to a few times earth 's mass .
但是,近年来天文学家通过径向速度法去发现或证实大量小到只有几倍的地球质量的行星。
The new planetary system was discovered using the radial velocity method , which detects the wobble in a star caused by the gravitational pull of an orbiting planet .
这个新的行星系统是使用径向速度法发现的,该方法可以检测到因行星重力牵引所带来的恒星的微幅晃动。
Controlling the source of light in your designs ( even if just with a linear or radial gradient ) can help create atmosphere in your page designs .
控制好光源位置能够为你的页面设计创造独特气氛(即使仅仅是一个简单的线性或径向渐变也能达到效果)。
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 .
The radial veolcity technique has also been used in the discovery of three new planets orbiting in the habitable zone of a red dwarf star called gliese 667c .
天文学家使用径向速度法还发现了围绕一颗名叫葛利斯667c的红矮星旋转、位于宜居区的三颗新行星。
These findings seem to agree with what planet hunters are finding so far when they use radial velocity studies to detect extrasolar planets around other stars .
The planetary treasure trove was found using an instrument called harps-short for high accuracy radial velocity planet searcher-at the european southern observatory 's la silla facility in chile .
