How do scientists determine the chemical makeup of the stars?
Different chemicals emit and absorb light at various wavelengths. Astronomers can look at the wavelength of light coming from stars and determine which chemicals must be present.
What are the other instruments used by astronomers in gathering information about stars?
Astronomers use instruments such as spectrometers to analyze starlight and determine a star's chemical composition, temperature, and motion. Telescopes are used to observe stars and capture images at different wavelengths. Interferometers combine signals from multiple telescopes to create high-resolution images of stars and star systems.
What type of electromagnetic wave helps astronomers to determine the hottest stars?
Astronomers use ultraviolet (UV) electromagnetic waves to determine the hottest stars. These stars emit significant amounts of their energy in the ultraviolet spectrum due to their high temperatures, often exceeding 30,000 Kelvin. By analyzing the UV light they emit, astronomers can gauge their surface temperatures and understand their physical properties. This information is crucial for studying stellar evolution and the characteristics of different types of stars.
What instrument do the astronomers use to determine the chemical composition of the star?
MY ANSWER IS....SPECTROSCOPE....because stars can seen through spectroscope...:)) sorry kung ganito lang kasimple yung answer ko...im just a grade 6 pupil lang kasi.. nice to meet you all... -Dulce Dumapias...add me on facebook..ahaha:)) see you there..:))
How do astronomers determine the surface temperatures of the stars?
Astronomers determine the surface temperatures of stars by analyzing their spectrum of light. Each star emits a unique spectrum based on its temperature which can be measured using instruments like spectrographs. By comparing the observed spectrum to known temperature profiles, astronomers can estimate the surface temperature of a star.
What are two kinds of information astronomers can collect from stars by using spectrographs?
compositions and temperatures
How do scientists determine the chemical makeup of the stars?

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.
Why is the HR diagram useful to astronomers?
It can be used to determine a Stars lifetime, its different stages.
How does a spectroscope enable astronomers to determine the characteristics of distant stars and galaxies?

Why might astronomer would most likely use the principles of chemistry?
An astronomer would use the principles of chemistry to determine the chemical components of distant planets and stars. The most useful discipline is that of spectral analysis. This is the identification of chemical compounds by their actions on various wavelengths of light.
How do astronomers determine the precession of the earth?
By finding a constant, continuous change in the coordinates of stars every year.
Rocks are to geologists as stars are to?
Rocks are to geologists as stars are to astronomers.
