The temperature of a star is determined for it's colour spectrum.
The hotter the star the more the spectrum is towards blue where as a cooler star has a spectrum closer to red.

What can electromagnetic spectrum tell us about a star?
Information that you can find about the star by looking at its spectra is its luminosity, surface temperature, its type(common/rare), color, how/if a star is moving, the density, the size, and future of the star. 2. And looking for spectral lines informs as to what elements are present.
What is the color and the temperature of the star Alnilam?
Alnilam is a blue-white super giant star, with a surface temperature of around 27,000 Kelvin.
If a certain star has a peak wavelength of 700NM then its surface temperature is about?
4200K
What does it mean if a star has similar size and surface to the sun?
It means that it is the same size and surface temperature as our sun.
What is the temperature of Baham?
If you mean the star in Pegasus (Theta Pegasi), its surface temperature is about 7700 degrees Celsius.
What can a stars spectrum tell astronomers about a star?
What elements the star is made of.
What information can astronomers obtain by studying the spectra from stars?
They can obtain information about what elements are in the star; about the star's temperature; about whether the star is moving towards us or away from us; and partial information about the star's rotation.
The temperature of a star is actually the temperature of what?
the surface of the star.
What is the dependent ability for elements to absorb light in stellar atmospheres?
The dependent ability for elements to absorb light in steller atmospheres is the surface temperature of the star.
What is the surface temperature of the Acamar star?
About 7900 degrees Celsius, surface temperature.
What do the color and lines in the spectrum of a star indicate?
By looking at the lines in a star's spectrum of light, astronomers can tell what kinds of elements the star is made of. This happens because when a beam of light hits an atom or molecule, that atom absorbs a characteristic wavelength (color) of visible light. Scientists have made a huge list of different elements and the different patterns of lines observed in theirj corresponding "spectra" (fancy word for light spectrums), and by using such lists can deduce precisely what each star is made of.
Does a red star have a higher surface temperature than a blue star?
Yes, the blue stars surface temperature can reach over 25,000K
What is the color of the star with the lowest surface temperature?
the color of stars with the lowest surface temperature is red
What surface temperature is polaris?
The surface temperature of the main star of the Polaris system is 6015 K.
What star has a higher surface temperature blue star or a red star?
Blue.
How is a star's surface temperature determined?
pyrometry
What is the surface temp of the star Eltanin?
Surface Temperature: 4000 K
