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.
The surface temperature of a star is indicated by what physical characteristic?
The surface temperature of a star is indicated by its color or spectral type. Blue stars have higher surface temperatures compared to red stars. By analyzing the star's color and spectrum, astronomers can determine its surface temperature.
Which stars have the highest surface temperatures red star or blue stars?
Blue stars have the highest surface temperature, at over 7,500 Kelvin. The surface temperature of red stars is less than 5,000 Kelvin.
What color and surface temperature?
Stars come in various colors depending on their surface temperature. Hotter stars, like blue ones, have higher surface temperatures, while cooler stars, like red ones, have lower surface temperatures. The color and surface temperature of a star are generally related, with blue stars being hotter (around 10,000 K) and red stars being cooler (around 3,000 K).
What color star has the highest surface temperature?
Red stars have the coolest surface temperature. Blue color stars have the highest surface temperature. The Sun belongs to the main sequence stars.

What is the color of stars with the lowest surface temperature?
the color of stars with the lowest surface temperature is red
How did early scientist group stars?
Temperature
How do stars get their colors?
The Color of stars depends upon their surface temperature.
Blue vs red stars?
Red stars have the coolest surface temperature while blue stars have the highest surface temperature. NERD!
What is the color of the stars that have the lowest surface temperature is?
Red stars have the lowest surface temperatures.
Which stars have the highest surface temperatures red star or blue stars?
Blue stars have the highest surface temperature, at over 7,500 Kelvin. The surface temperature of red stars is less than 5,000 Kelvin.
What classification of stars has the lowest surface temperature?
Black dwarfs have the lowest surface temperature.
Scientists determine the composition and temperature of stars?
To determine the chemical composition of stars, scientists look at what's called the emission spectrum of the stars, which can be obtained from the light coming from the stars. Thin lines are observed in different parts of the spectrum, which correspond to different chemicals. In other words, the lines are like fingerprints of chemicals. By looking at these fingerprints, one can determine what type of chemicals are present in the star. To determine the surface temperature of stars, we use the Wien's Law. It states that: Peak wavelength x Surface Temperature = 2.898x10-3 Peak wavelength can be determined by looking at the light coming from the star in question. It is the wavelength with the highest intensity.
What determines how bright stars are?
Size and temperature determine the brightness of stars.
What is the color of the star with the lowest surface temperature?
the color of stars with the lowest surface temperature is red
