How do astronomers determine the chemical compositions of stars?
The answer is long and complicated, and it is too long to place here. You need to read an entire encyclopedia articles on spectroscopy and the chemical composition of intersteller objects. D.A.W.
The set of spectral lines that we see in star's spectrum depends on the stars?
composition and temperature. The spectral lines correspond to different elements present in the star and the wavelengths of these lines are affected by the star's temperature. By analyzing these lines, astronomers can determine the chemical composition and other characteristics of the star.
How do astronomers determine the composition of distant celestial objects?
Spectroscopy is the systematic study of spectra and spectral lines. Spectral lines are used to provide evidence about the chemical composition of distant objects. So the answer to your question is through spectroscopy.. not spectrometry like the previous editor posted.
What does the spectrum of a star determine?
The spectrum of a star provides information about its temperature, composition, and motion. By analyzing the spectrum, astronomers can determine the star's chemical makeup, age, and even whether it is moving toward or away from Earth.
What instrument can be used to collect important information about stars composition from Earth?
Spectrometers are the instruments used to collect important information about a star's composition from Earth. By analyzing the light emitted or absorbed by a star, spectrometers can identify the presence of various elements and molecules based on their unique spectral lines. This technique, known as spectroscopy, allows astronomers to determine the chemical makeup, temperature, mass, and other properties of stars.
What instrument do the astronomers use to determine the chemical composition of a star?
They use a spectrograph to pass light through a prism to break it the light waves into its constituent colors. Then by looking at what colors are missing they can determine both the temperature and composition of the star.

If Astronomers observe a typical star using a telescope and a spectrometer they will be able to determine what?
Astronomers can determine the star's temperature, chemical composition, mass, luminosity, and age by analyzing its spectrum. By studying the absorption and emission lines in the spectrum, astronomers can also infer the star's motion, magnetic fields, and if it has any companions such as planets or other stars.

How did astronomers in the 19th century gather information about the chemical composition of stellar objects?
There is one way for gathering information about chemical composition of stellar objects - spectral analysis! Astronomical spectroscopy began with Isaac Newton's initial observations of the light of the Sun, dispersed by a prism. He saw a rainbow of colour, and may have seen absorption lines. The absorption lines in stellar spectra can be used to determine the chemical composition of the star.
How does a spectrograph provide information about stars chemical composition?
A spectrograph breaks down the light from stars into its component colors or wavelengths. Each chemical element absorbs and emits light at specific wavelengths, creating a unique fingerprint called a spectral line. By analyzing the spectral lines in a star's light, scientists can determine its chemical composition.
Spectrographs help astronomers determine a star's what?
The star's chemical composition; the star's rotation; pulsations of the star; planets or other invisible objects moving around the star; how quickly the star is moving towards us or away from us.
What are the factors that determine the thermal energy of a substance?
Its mass and and its chemical composition.
