In the end, the RSFPA algorithm is validated by using star spectrum data as experiment data.

最后，利用恒星光谱作为数据集，实验验证了RSFPA算法的正确性和有效性。

If you were looking at the spectrum of some other star, the colors would be the same.

如果你观察其他恒星的光谱，你会发现它们的颜色是一样的。

For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum.

例如，经过训练的观察者主要通过对光谱中出现的简单线条的精确分析来获取关于恒星的大量信息。

For each night's observations, they added all the spectra they collected together to obtain an average spectrum for the star, and then subtracted this average spectrum from each observation.

ECONOMIST: Extrasolar planets

Several monster planets have been discovered by looking for the wobbles in a star's spectrum caused by a planet's to-and-fro tugging of its parent.

But some theorists believe that when it is possible, they will be able to determine how a particular object formed by comparing its spectrum with that of its parent star to determine the relative proportions of heavy elements in the two bodies.
