Machine-learning approaches have been used to filter and classify Kepler data before, but Shallue's neural network offered a far more powerful algorithm.
该频率与FMCW雷达的载波频率遵守相同的规律(如多普勒效应)。
This frequency is subject to the same laws(e.g. Doppler effect) as the carrier frequency in FMCW radar.
这项开普勒太空望远镜的最新使命帮助天文学家采集了最完整的昂宿星团恒星自转速度。
The latest mission by the Kepler space telescope has helped astronomers collect the most complete catalog of spin rates among the stars of the Pleiades cluster.
他表现出超声波脉冲多普勒测距选通,并且是恶性肿瘤新血管形成的超声多普勒信号特性的发现者。
He demonstrated ultrasonic pulsed-Doppler range-gating, and was the discoverer of the ultrasonic Doppler signal characteristic of malignant tumour neovascularisation.
然而到1624年,紧张关系的升级以及预言的不准确意味着给开普勒自身带来的政治麻烦;.
By 1624, however, the escalation of those tensions and the ambiguity of the prophecies meant political trouble for Kepler himself;
这为天文学家提供了一种发现行星的新方法,那就是利用多普勒效应。
And that gives astronomers a way to find them, using the Doppler effect.
最终,TESS将探测90%的天空,它的探测范围将比开普勒太空望远镜大400倍。
As a result, TESS will detect 90% of the sky and will be able to detect 400 times more than the Kepler Space Telescope.
用我们的工作模型,我们拍摄了恒星,用它来寻找开普勒数据中的新行星。
Armed with our working model, we shot for the stars, using it to hunt for new planets in Kepler data.
在个人写给开普勒在1598年,伽利略指出,他是一个哥白尼(相信哥白尼的理论)。
In a personal letter written to Kepler in 1598, Galileo had stated that he was a Copernican(believer in the theories of Copernicus).
这一宣布使开普勒证实的行星数目增加了一倍以上。
The announcement more than doubled the number of confirmed planets from Kepler in one sweep.
但这并不能解释开普勒观测到的一个令人困惑的问题:相当于地球半径1.5倍到两倍之间的行星非常少。
But that can't explain a puzzling gap observed by Kepler: There are very few planets with sizes between 1.5 and 2 Earth radii.
齐伯斯坦很好奇,想知道开普勒的论文中是否会出现类似的金属。
Zilberstein was curious to see if similar metals would turn up in Kepler's papers.
为了这批新发现,科学家们从开普勒发回的大量数据中进行了筛选。
For these new discoveries, scientists screened a large amount of data back from Kepler.
月26日,科学家宣布从开普勒数据中,证实了715颗新的系外行星。
On February 26, scientists announced that data from Kepler had confirmed the existence of 715 new exoplanets.
