3 For example, when an exoplanet movesbetween its star and us,it causes a small drop in the star's brightness. Measuringthis drop is the transit(凌日) method of discovery. NASA's Kepler space telescopehas discovered many exoplanets in this way.As a planet circles a star, it pulls on ...
推理判断题.根据后文Although not the first exoplanet discovery, a planet near a sun-like star was discovered by astronomers in 1995可知然而,只有在过去的几十年中,我们才发展出技术来证明他们的存在;故选E。推理判断题。根据后文However, in 2015NASA's Kepler space telescope found its first Earth-size...
The first method is designed to find planets using the data from the K2 phase of the Mission where systematics introduced by the instrument dominate the measurements. Applying this method to the first publicly available dataset from K2, Campaign 1, I published more than thirty new exoplanet ...

The main directions pursued in this article are: (1) given two periodic orbits, decide when they can be connected by a regular family; (2) use numerical invariants from Floer theory which help predict the existence of orbits in the presence of a bifurcation; (3) attach a sign +/- to ...
“Embrace some of the messiness of natural environments,” since it will help with engineering technologies resilient to such variability. The discovery of the central role of the microbiome in health and disease has shifted medicine, says Don Ingber, director of the Wyss Institute for Biologically...
Increasing production of second-generation biofuels—those made from non-food biomass such as switchgrass, biomass sorghum, and corn stover—would lessen our reliance on burning fossil fuels, which contributes to climate change. Several barriers have prevented the efficient conversion of that biomass. ...
of scientific discovery. We compared the performance of four novelty detection methods—Reed Xiaoli (RX) detectors, principal component analysis (PCA), autoencoders, and generative adversarial networks (GANs)—and the ability of each method to provide explanatory visualizations to help scientists ...
Microorganisms comprise the majority of living organisms on our planet. For many years, exploration of the composition of microbial communities has been performed through the PCR-based study of the small subunit rRNA gene due to its high conservation acr
1 Although not the first exoplanet discovery, a planet near a sun—like star was discovered by astronomers in 1995. This kicked off an era of exoplanet hunting, with thousands of discoveries and confirmations following in its wake 2 However, in 2015 NASA's Kepler space telescope found its ...
