What is a Hertzsprung-Russell diagram and how do astronomers use it?
i really o not understand the significance of the question that is asking
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 kind of an impact did Aratus have on other astronomers?
Aratus knew quiet a bit about the stars. He was able ( through his writings ) to give the location of all the constalations he knew of. I guess he struck other astronomers for his knowledge about the stars: knowledge it took them a while to gain.
Who is one of the propounders of the binary star theories?
All serious astronomers realize that there are binary stars.

To compare and classify stars.
Spectral lines are of particular importance in astronomy because?
For one reason, astronomers can figure out what stars are composed of by looking at their spectral lines.
What is used to help humans determine temperature of the stars?
spectral analysis
What used to help humans determine the temperature of stars?
spectral analysis
What provides info about the chemical composition of stars?

Identify two ways in which astronomers can use an H-R diagram?
Classify stars and to understand how stars change over time
What does a H R Diagram compare?
The H-R diagram compares a star's surface temperature to its absolute brightness.
