... a photonic 'fingerprint'. The picture of a star's spectral lines is its photo-spectrograph.
The dark lines are absorption spectrum, the energy absorbed by Atoms in the atmosphere of the star. ================================ Fraunhofer's spectral lines.
That's done by analyzing the star's spectrum.

the answer to this question is when you use the power around you and it comes in as one so basically that is why it is called solar power
If the spectrum of a star is blue-shifted, it indicates that the star is moving towards the observer. This shift occurs because the wavelengths of light from the star are compressed as it approaches, resulting in a shift towards the blue end of the spectrum. This phenomenon is a consequence of the Doppler effect, which applies to all types of waves, including light.
It's called a spectrum. I've never heard any other term used for it.
The change in a star's spectrum when it moves away from the Earth is called redshift. This shift occurs because the wavelengths of light emitted by the star are stretched out as the star moves away, causing the light to appear more red.

That is called "redshift". The frequency of the radiation decreases.
There is a change in frequency; this effect is called "Doppler effect".
The dark lines that appear in a spectrum of light from a star are called absorption lines. These lines are caused by the absorption of specific wavelengths of light by elements in the outer atmosphere of the star. Absorption lines help astronomers identify the chemical composition of stars and other celestial objects.
By the star's spectrum.
They analyze the star's spectrum. Each element produces characteristic lines in a spectrum.
The spectrum of light from a star appears continuous, without gaps, because it is a result of the superposition of light emitted at different wavelengths. This continuous spectrum is produced as the star emits light across a range of wavelengths leading to a smooth distribution of colors in the spectrum.

The spectrum is a kind of analysis of the light emitted by a star.
