What is the hottest flame? Yes it is true that white flame is the Hottest but regarding the spectrum of heat we are totally confused.In one direction you are right that the Red is cooler than the Orange , Orange flame is cooler than Yellow and Yellow Flame is cooler than White Flame,But on the other hand the Cyan Flame is cooler than the White , Blue is cooler than Cyan and Violet Flames are cooler than the Blue Flames.Green Flames are the mixture of Cyan and Yellow Flame so the total heat will be in between .It is ...

- First, let’s talk about temperature. As I mentioned above, the color of a star comes from its surface temperature. A star that emits mostly red light will have a surface temperature of about 3,500 Kelvin. Just for comparison, the Sun’s surface temperature is about 6,000 Kelvin and emits yellow/white light.Red Dwarf Stars.The first kind of red stars are red dwarfs.These are actually the most common stars in the Universe.he color of a star comes from the temperature of its surface. The hottest stars are blue, cooler stars are white and yellow, and the coolest stars of all are red. Red stars come in one color, but many different shapes and sizes. Let’s take a look at the different kids of red stars that are out there in the Universe.

Color of Stars The color of a star depends on its surface temperature. Our Sun's surface temperature is about 6,000 Kelvin. Although it looks yellow from here on Earth, the light of the Sun … would actually look very white from space. This white light coming off of the Sun is because its temperature is 6,000 Kelvin.

What is the hottest object in the universe? On a typical day, one contender is the white dwarf that is at the heart of the Red Spider Nebula (NGC 6537). The surface temperature of that star is around 300,000 K (540,000 R). That's 50 times hotter than our sun. Or you could go with a quasar, where the center burns 100 times as much energy as the Milky Way. The gas around a quasar can reach a temperature of 80 million degrees.

The Colour of Stars Red giants such as Betelgeuse are not actually that red in colour. If you look at the colour in table 4.3 above you can see that its actual colour would be more orange than true red. A small group of stars do, however, appear deep red. These are the carbon stars such as 19 or TX Piscium.

General Astronomy/Temperature < General Astronomy. The temperature of a star refers to its surface and that is what determines its color. The lowest temperature stars are red while the hottest stars are blue. Astronomers are able to measure the temperatures of the surfaces of stars by comparing their spectra to the spectrum of a black body.

Star Temperatures Stars approximate blackbody radiators and their visible color depends upon the temperature of the radiator. The curves show blue, white, and red stars. The white star is adjusted to 5270K so that the peak of its blackbody curve is at the peak wavelength of the sun, 550 nm. From the wavelength at the peak, the temperature can be deduced from the Wien displacement law.

How does a stars temperature change as the star ages from a main sequence star to a red giant and from a red giant to a white dwarf? Confidence votes 489. A regular stars temperature cools as it balloons into a red giant. The color shift is evident by the word red because red is the coolest color of heat. The surface of a dying star is cool because it is so much farther away from the core than when it is on the main sequence.he color shift is evident by the word red because red is the coolest color of heat. The surface of a dying star is cool because it is so much farther away from the core than when it is on the main sequence.

The Colour of Stars Most appear white but a few stars such as Antares and Betelgeuse have an orange or reddish hue to them. Others such as Rigel suggest a bluer colour. The colours of stars, however, are not obvious in most stars for several reasons discussed below. Colour is nonetheless an important and useful property of stars.

Why are stars different colors? There is another important factor that can alter a stars color. If the star has any elements in its atmosphere it can change the light wavelength and that will cause a change in the color that we measure or observe. This may explain why there are so many different colors in the stars that are being studied. The coolest stars are the red stars and their temperature is around 3,000 degrees C.

HOW HOT IS A STAR? Cool stars (such as Betelgeuse, which has a surface temperature of T = 3500 Kelvin) emit more red and orange light than blue and violet light. Thus, cool stars are red. Hot stars (such as Rigel, which has a surface temperature of T = 15,000 Kelvin) emit more blue and violet light than red and orange light. Thus, hot stars are blue. One way of classifying stars is by their temperature; stellar temperatures run from about 2500 Kelvin to about 50,000 Kelvin.

Star brightness versus star luminosity Surface temperature. Also, if a star has the same radius as the sun but a higher surface temperature, the hotter star exceeds the sun in luminosity. The sun’s surface temperature is somewhere around 5800 Kelvin (9980 o Fahrenheit).That’s 5800 degrees above absolute zero, the coldest temperature possible anywhere in the universe.et’s presume a star has the same surface temperature as the sun, but sports a larger radius. In that scenario, the star with the larger radius claims the greater luminosity. In the example below, we’ll say the star’s radius is 4 solar (4 times the sun’s radius) but has the same surface temperature as our sun.

KenCroswell.com As a star evolves, its temperature, luminosity, and diameter change. At present, Procyon is slightly hotter than the Sun, with a temperature of 6,530 Kelvin (versus the Sun's 5,770 K). Its luminosity over all wavelengths is about seven times the Sun's, so it emits as much light in a day as the Sun does in a week.
