What do astronomers use to determine the chemical composition in star?
The light that comes from the star. The light is spread out into its spectrum and the pattern of spectral lines allow the composition (and temperature) to be determined. The temp can also be found by looking at the black body curve for the star (also from spectrum), or, by looking at the color of the star (difference in intensity of the light through two different color filters typically B and V.

What are the 2 factors that brightness of a star is determined by?
How dense it is, and how far away it is.
How is a star simmular to the Sun if it has the same absorption lines in its spectrum that occur in the Sun's spectrum?
because they will have the same elements in the atmosphere...
What are some of the star characteristics that can be identified by spectral analysis?
Spectroscopic surveys are based on the fact that the colors you see in everything are not in the object being observed, but is the result of the fact that the elements that make up the object, are reflecting that part of the spectrum of light that strikes it. Spectroscopic analysis will give researchers an idea of the basic makeup of the star.
Is there Star Wars poptropica?
No, but I wish there was. ):
The chemical composition of a star can be determined using a?
spectrophotometer or laser spectroscope
Can composition of stars can be determined by examining their colors?
Yes, the composition of a star can be determined by analysis of its color, which would be described scientifically as spectrographic analysis.
Which characteristic determines the color of a star?
The colour of the star is determined by its age , mass , and composition.
What makes a star's spectrum appear to be different from another stars?
The chemical composition of the star.
What determines the way a massive star dies?
the star's mass, chemical composition, and size of it when it is born
Spectrum indicates what in the stars atmosphere?
The chemical composition of the star atmosphere.
The spectral type of a star measure?
The spectral type of a star is what measures its chemical composition. The visible light that bounces off of it can be used to determine the composition.
Which property of a star is directly indicated by the lines on its absorption spectrum?
Chemical composition
The set of spectral lines that we see in star's spectrum depends on the stars?
Chemical composition ;-)
How does astrophysics connects to chemistry?
Any cosmic object (star, planet, meteorit, comet) has a 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 is the proof that the sun is a star?
It is hot and luminous. It has the same spectral qualities of other stars. It's chemical composition is the same as other stars. It's a star - We call our star the Sun.
