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 are athletes tested for drug use?

Urine and/or blood samples are sent to a laboratory for analysis with various tools such as gas chromatography chemical reagents and spectral analysis.


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.


Which tool would an astronomer most likely use to collect information about the chemical makeup of a star?

A telescope, whose light output would be sent through a spectral analysis machine of some type. That analysis of the emission spectra of the star would be compared to the known spectra of the elements to find the composition of the star.


Suppose you want to know the chemical composition of a distant star Which piece of information is most useful to you?

The wavelength of the the spectral lines in the stars spectrum.


How is the presence of Urobilinogen treated?

Spectral analysis.


How does absorption and emission spectra identify elements?

Each chemical element has specific emission or absorption spectra. Spectral analysis is widely used in analytical chemistry.

A spectral analysis of indium would show that it emits a very strong indigo colored line.


How do spectrometers work?

spectrometers split light, then the spectral lines show , and you can use spectral analysis to find out what elements are making the light.
