What is a sentence with spectral line?
A spectral line refers to the distinct lines in a spectrum that correspond to specific wavelengths of light emitted or absorbed by atoms or molecules. For example, astronomers analyze the spectral lines of distant stars to determine their composition and temperature.
What is the classification for large cool stars?
Large cool stars are classified as either K or M type stars on the spectral classification scale, with M stars being cooler and redder than K stars. These stars are part of the main sequence on the Hertzsprung-Russell diagram and have surface temperatures lower than 5,000 K.
What color is gliese?
Gliese does not have a specific color as it is a designation for a star within the Gliese catalog of nearby stars. The color of a star is determined by its temperature, with hotter stars appearing bluer and cooler stars appearing redder.
When astronomers look for evidence of hydrogen gas in the spectra of the Sun the planets and nearby stars the positions of the spectral features or lines due to hydrogen are different or the same?
They are the same.

What color stars have the lowest temp?
Typically the bigger and redder stars are the hottest.
Is spectral type k hotter then spectral type a?
No. K spectral type stars (which are orange) temperature is ranging from 5,000-3,500. A spectral type stars (which are blue-white) temperature is ranging from 7,500-11,000.

They are the same.

When was Distant Stars created?
Distant Stars was created in 1981.
How many pages does Distant Stars have?
Distant Stars has 352 pages.
The distance to nearby stars can be measured by using?
The distance to nearby stars can be measured using the parallax effect. Astronomers observe the apparent shift in position of a star against the background of more distant stars as the Earth orbits the Sun, allowing them to calculate the star's distance based on the angle of the shift.
Why are elliptical galaxies redder than disk galaxies?
Actually, it doesn't matter what kind of galaxy it is, because it depends on what kind of stars are in it. If a galaxy has a lot of red giants, it will appear redder than a galaxy with mostly blue-white stars. Older galaxies might be redder than younger galaxies due to the fact that older stars appear redder.
When esimating the distance of the stars from earth astronomers use the fact that nearby stars shift in position as observed from earth which is called?
Nearby stars appear to change their position against the distant background in an annual cycle, because of the Earth's changing position 'across' its orbit. This apparent shift is called the star's "parallax".
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.
