How do scientist determine the surface temperature of the stars?
Scientists determine the surface temperature of stars by analyzing their spectral characteristics. They use a device called a spectroscope to split the starlight into its component colors, which reveals absorption lines that correspond to specific elements. By studying the intensity and distribution of these lines, scientists can calculate the surface temperature of the star.
How can the color of starlight reveal the temperature of a star?
The color of starlight is related to its temperature through Wien's Law, which states that hotter stars emit light that appears more blue/white, while cooler stars emit light that appears more red. By analyzing the color spectrum of starlight, astronomers can determine the peak wavelength of light emitted by a star, allowing them to calculate its temperature.
Temperature and brightness of stars are indicated by what?
Temperature of stars is indicated by their color, with blue stars being hotter than red stars. Brightness of stars is indicated by their luminosity, which is how much light a star emits.
Are stars all the same color?
Stars come in different colors based on their temperature. Hotter stars appear blue or white while cooler stars can appear red or yellow. The color of a star is an indication of its temperature and stage in its life cycle.
Are all bright stars the same temperature?
No, bright stars can have different temperatures. The color of a star typically indicates its temperature, with blue stars being hotter than red stars. Brightness is influenced by both temperature and size; a larger, cooler star could appear brighter than a hotter, smaller star.

What is the name of the chart of the diagram we use to classify stars?
The chart used to classify stars is called the Hertzsprung-Russell diagram (H-R diagram). This diagram plots stars based on their luminosity and temperature, helping to illustrate their evolutionary stages. It reveals relationships between different types of stars, including main-sequence stars, giants, and white dwarfs.

What is the color of stars with the lowest surface temperature?
the color of stars with the lowest surface temperature is red
Blue vs red stars?
Red stars have the coolest surface temperature while blue stars have the highest surface temperature. NERD!
Temperature and brightness of stars are indicated by what?
Temperature of stars is indicated by their color, with blue stars being hotter than red stars. Brightness of stars is indicated by their luminosity, which is how much light a star emits.
How do stars get their colors?
The Color of stars depends upon their surface temperature.
Are stars all the same color?
Stars come in different colors based on their temperature. Hotter stars appear blue or white while cooler stars can appear red or yellow. The color of a star is an indication of its temperature and stage in its life cycle.
What stars are hot and which are cold?
All stars are hot. Their temperature can be determined by their color. The "coolest" stars are red in color. As temperature increases stars will go through orange, yellow, white, and finally blue for the hottest stars.
How do colors of stars change with temperature?
White stars are usually the hottest, followed by blue stars and then red stars.
Are all bright stars the same temperature?
No, bright stars can have different temperatures. The color of a star typically indicates its temperature, with blue stars being hotter than red stars. Brightness is influenced by both temperature and size; a larger, cooler star could appear brighter than a hotter, smaller star.
What determines how bright stars are?
Size and temperature determine the brightness of stars.
