Color Scientists use spectrometers to create
the color patterns produced by suns light
Thus they can use spectrometer on earth with
some hot source to see what colors it can give
and thus the colors on sun can tell their temperature. This method is called Spectral Classification.
Astronomers measure the temperature of the Sun by analyzing its spectrum of electromagnetic radiation. They use instruments such as spectrographs to observe the wavelengths of light emitted by the Sun. By studying the intensity of different wavelengths, they can determine the temperature of the Sun's outer layers.
I don't know if they can measure the exact temperature, but it depends on the star's color.
If it is white or blue, they are extremely hot.
If it is yellow, like ours, it is medium temperature.
If it is red or orange, they are cooler stars, but still really hot.
Optical interferometry is the process to measure stellar radii. In essence, this is basic triangulation. Two telescopes are used which establishes the base of the triangle for calculation. The distances can then be determined and the radius of the star in question can be derived.
Scientists analyze the spectrum of a star to tell the temperature of stars.
By noting the wavelength at which the radiation emitted by the star is the most intense, we can calculate the star's temperature from Wien's displacement law.
Stellar temperature can be measured by analysing the spectrum of light that stars emit; shorter wavelengths correspond to higher temperatures.
By analysing it's spectrum. Blue is hot, red is cool.
See related question.
Depends on the color. Blue stars are the hottest, red stars are the coolest and the yellow stars are medium in temperature.
Astronomers can tell how hot a star is by the stars color. Different colors mean different elements that burn and frequencies which is the pressures in the stars.

What do astronomers do to-learn about properties of stars?
The almighty spectroscope, it breaks the holy light coming from the star into different colors so we can actually examine it's properties without going blind or incinerating ourselves.
Name and describe the phase change that occurs when dry ice is placed in an opened container at room temperature?
Dry ice (solid CO2) at room temperature changes from a solid to a gas without going through the liquid phase. This is called sublimation.
When temperature is decreased on a gas and it becomes a solid without a liquid stage this is called?
This process is called deposition. It involves the direct transition of a gas to a solid without passing through the liquid phase.
What is a direct change from a solid to a gas?
Sublimation is the direct change from a solid to a gas without going through the liquid phase. This process occurs when the solid's vapor pressure exceeds the atmospheric pressure at a specific temperature.
Is it true that a giant asteroid is about to hit the earth in 2014?
No, there is no evidence to support the claim that a giant asteroid was going to hit Earth in 2014. Astronomers keep a close eye on potentially hazardous asteroids, and there are protocols in place to deal with any potential threats.
Is there a job related to an astronaut?
An astrologist maybe. Some astronomers study space without going to space lol
How do you take care thermometer?
the thermometer is an object that we going to measure of an temperature of one person.
Can you measure distance without a tape measure?
well, a stopwatch and a speedometer will do. Get the speed and time of going through this distance, and multiply by them, you will get the number.

Why astronomers don't think the world is going to end in 2012?
Because there is no evidence to suggest that it will
How did the Chinese kites impact their society?
kites have had a significant impact on the society and environment. Kites can measure the temperature for the weather which leads to people knowing what the weather is going to be for the day.
Astronomers are interested in solar neutrinos because neutrinos carry with them information about?
The nuclear reactions going on in the heart of the Sun.
How have past astronomers learned about Neptune?
Jasleen Kaur Dhunna sucks!. that's all im going to say!
How do you know if your air conditioner in overcharged?
With refrigerant gauges we read the pressures and measure the temperatures, without that we look at the amp draw and what the air temps are going in and out,
How is temperature related to kinetic energy?
Temperature is a measure of the average kinetic energy of the particles in a substance. As temperature increases, the particles gain more kinetic energy and move faster. Conversely, as temperature decreases, the particles slow down and have less kinetic energy.
What can astronomers learn by studying star properties?
Astronomers can learn the age, temperature, composition, size, and distance of a star by studying its properties. This information can help astronomers understand the star's lifecycle, predict its future evolution, and gain insights into the formation and evolution of galaxies. By studying star properties, astronomers can also identify patterns and relationships that can lead to new discoveries and advancements in our understanding of the universe.
