All stars have different temperatures, depending on their mass and period in their life cycle. The hotter a star is, the brighter it will appear.
The stellar classification [See link] in order of temperature. Our Sun is classed as yellow.
See link [Kelvin] for conversion ratios.
These temperatures are the surface of the stars. The cores of the stars are much hotter, around 15 million degrees for our sun.
aprox. 5467,098 degrees
Your average star temperature is around a few thousand degrees Celsius. However, stars vary enormously, and they have a great range of temperatures. Depending on the type of star, its surface temperature can be as hot as one trillion degrees Celsius at one extreme and at the other extreme, in theory, a star can become nearly as cold as outer space.
It is also worth considering that a star's temperatures can vary depending on where on the surface, or how deep inside, of the star you measure. Starspots can locally lower the surface temperature of a star by thousands of degrees Celsius and the inside of a star is usually much hotter than its surface. For example, the average surface temperature of our local star, the Sun, is 5,500 degrees Celsius but some Sunspots can have a temperature much lower, at 2700 degrees Celsius. In the Sun's centre, its core, temperatures reach up to 15 million degrees Celsius.
Stellar flares can erupt away from a star's surface and these too can have temperatures much higher than that of the surface. Some flares on our Sun can reach 10 million degrees Celsius but they do cool down very quickly after they erupt.
The temperature of a star usually refers to its surface temperature as historically this was the first temperature reading to be measured. Early astronomers, using telescopes and prisms, were able to calculate the temperature of a star either by looking at the colour of the visible light emitted from the star's surface or by looking at the detail of the spectral lines in the starlight which by their presence, or not, reveal the temperature of the elements in the outer atmosphere of the star.
Generally, the hotter a star is, the brighter and bluer it will appear, and the colder the star is, the darker and redder it will appear.
The Types of Stars and their different temperatures:-
Main Sequence and Subgiant Stars-
Giant and Supergiant Stars-
These stars have temperature ranges comparably similar to Main Sequence Stars, but typically a few hundred degrees Celsius colder due to their fuzzier and diffuser outer atmospheres. So, for example, an orange giant star can have a surface temperature between 3,300 and 4,600 degrees Celsius, about 400 degrees Celsius colder than the range for orange dwarf stars.
Other Stars-
No, they jolly well aren't! It's their heat that makes them white.
Stars are enormous balls of gas that are continually exploding at the scale of millions of tons of TNT every minute. They are quite warm, even when white.
No, white stars are not cold. Technically, no stars can be 'cold,' some are just warmer than others. White stars are one of the hotter kind of stars.
red stars are less than 3,500 degrees Celsius and are the coolest among the stars.
These are the stars with a spectral classification of 'A'. They have surface temperatures between 7,600 and 10,000 kelvin.
No. Blue stars are the hottest.
Bluish-white
Yes it is
A white dwarf is what remains of a star's interior, which is much hotter than the surface because it is closer to the source of fusion.
All stars are hot. A white star is hotter than average with e temperature of about 7,200 to 9,200 degrees Celsius.
An orange star is hotter than a red star.
Well I know this is not what you had in mind but white stars are hotter! If you where to compare, the blue stars would be hottest then the white stars, yellowish white, yellow orange then red. I know many people would have thought diffrently so face it our star (the sun) isn't the hottest.
Technically Blue stars are hotter but from your options, white stars are hotter.
The hotter the star, the closer to white the color.
Yes it is
It's not. White is the hottest. Then blue, yellow orange, red.
yes
The blue star is the hottest.
A white dwarf is what remains of a star's interior, which is much hotter than the surface because it is closer to the source of fusion.
Rigel is hotter by a long way with a temperature of 11,000 Kelvin, whereas Betelgeuse is a cool 3,500 Kelvin
No. Color, for stars, is (almost) entirely dependent on "surface" temperature, and white stars are significantly hotter then red ones. (The order from coolest to hottest goes brown, red, orange, yellow, yellow-white, white, blue-white, blue).
All stars are hot. A white star is hotter than average with e temperature of about 7,200 to 9,200 degrees Celsius.
The blue star is hotter
An orange star is hotter than a red star.
