The star is moving away fro where it is. ~Justine... :))
A spectrograph is a device that separates light from stars and other objects into its different wavelengths to produce a spectrum. This allows astronomers to study the composition, temperature, and other properties of the object emitting the light through analysis of the spectrum.
Scientists determined that the object was expanding by analyzing its light spectrum using a spectrograph. By observing the Doppler shift in the spectral lines, scientists could infer the motion of the object relative to Earth, leading to the conclusion that it was moving away and expanding.
The elemental composition of the materiel forming the spectrum.
The color of starlight is related to its temperature through Wien's Law, which states that hotter stars emit light that appears more blue/white, while cooler stars emit light that appears more red. By analyzing the color spectrum of starlight, astronomers can determine the peak wavelength of light emitted by a star, allowing them to calculate its temperature.
The electro magnetic spectrum - A prism can split light into a spectrum of colors, and starlight is light. Detail your question and you will have a detailed answer, if this answer does not do the job

Astronomers study the spectrum of light emitted by a star to learn about its characteristics. By analyzing the composition of elements, temperature, and density of a star, astronomers can determine its size, age, brightness, and life cycle stage.

A spectroscope is used to diffuse the light from a star into its spectrum, so that astronomers can analyze the elements that make up the star. The same sort of instrument can be used to analyze the elemental composition of ANYTHING; for terrestrial uses, the instrument is called a spectroGRAPH.

... a photonic 'fingerprint'. The picture of a star's spectral lines is its photo-spectrograph.

spectrometer is a device that gives the spectrum of all intensities of a one wavelength at one time. it consists of the entrance & exit slits, dispersing element (like grating) &mirror. it detects the light and measure the intensities with a photomultiplier tube or other detectors and data acquisition system. spectrograph also gives the spectrum of all intensities of a wavelength at one time.it consists of the entrance & exit slits, dispersing element (like grating) &mirror but it does not have any detector and does not record the spectrum.
Emission Spectrum
Astronomers use the Doppler effect to determine if a star is moving towards or away from us. By observing the shift in the star's spectral lines towards the blue end of the spectrum (blueshift) or the red end of the spectrum (redshift), astronomers can infer the star's motion relative to Earth. Blueshift indicates the star is moving towards us, while redshift indicates it is moving away from us.
