There are several things scientists can do to determine the surface temperature of a star. Formulas utilizing Wein's law and the Stefanâ??Boltzmann law can calculate stellar temperatures. However, for a rough estimate, scientists can also use the color of a star in order to determine surface temperature.
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…
One way in which a scientist can determine the surface temperature of a star is by: Step 1: launching a rocket to space Step 2: Ensure they have a thermometer with them. Note: The thermometer must be at least 20m long so as to reach the star whilst the scientist remain in the rocket Step 3: After having landed on planet Mars, the scientists open the shuttle of the rocket Note: they must be tied…
Scientists can determine the surface temperature of a star by measuring its color. (To do this quantitatively, they commonly use three filters that transmit light in three different wavelength ranges. Then they take the ratio of the intensity of the light that gets through, say, the shortest wavelength filter to the intensity of the light that gets through the medium wavelength filter.)
Yes. See the Wikipedia article on "Stellar classification". For example, a class "O" star (blue) has a surface temperature greater than 30,000 K, a class "A" star (white) has a surface temperature of 7,500 - 10,000 K, and a class "M" star (red) has a surface temperature of 2400-3700 K. (All temperatures use the absolute scale.)
