What is the range in temperature of stars?
The surface temperatures of A-type stars range from 7,400 K to about 10,000 K; lines of hydrogen are prominent, and these stars are white. F-type stars are yellow-white, reach 6,000–7,400 K, and display many spectral lines caused by metals.

The hottest one measures ~210,000 K; the hottest known star. The Wolf-Rayet star WR 102 is the hottest star known, at 210,000 K.
What stars have the highest temperature?
Type O stars have the highest surface temperatures and can be as hot as 30,000 Kelvins.
Which star has the highest temperature?
The hottest one measures ~210,000 K; the hottest known star. The Wolf-Rayet star WR 102 is the hottest star known, at 210,000 K.
How do you find the temperature of a star?
To get a stellar temperature:
- Measure the brightness of a star through two filters and compare the ratio of red to blue light.
- Compare to the spectra of computer models of stellar spectra of different temperature and develop an accurate color-temperature relation.
Which stars have the highest temperature?
Type O stars have the highest surface temperatures and can be as hot as 30,000 Kelvins.
How can you tell the temperatures of stars?
To the extent that Stellar spectra look like blackbodies, the temperature of a star can also be measured amazingly accurately by recording the brightness in two different filters. To get a stellar temperature: Measure the brightness of a star through two filters and compare the ratio of red to blue light.
What is the temperature of the coolest stars?
With surface temperatures hovering around 206 degrees F (97 degrees C), the newfound star is the coldest brown dwarf seen to date.
Why do stars have different temperatures?
The hotter the star, the shorter the wavelength of light it will emit. The hottest ones are blue or blue-white, which are shorter wavelengths of light. Cooler ones are red or red-brown, which are longer wavelengths. Stars, however, don't send out their light in one wavelength only.
What star has a temperature of 6000K?
Colours and temperatures Others stars appear blue, such as Sirius, the Dog Star. Sirius has a surface temperature of around 15000K. Our Sun is an average yellow star, with a surface temperature of about 6000K.
Why are stars different temperatures?
The hotter the star, the shorter the wavelength of light it will emit. The hottest ones are blue or blue-white, which are shorter wavelengths of light. Cooler ones are red or red-brown, which are longer wavelengths.
What determines temperature of a star?
So, to summarize, if a star is a brilliant blue color, it's really hot and emits a lot of energy. If it's red, it has a cool surface temperature instead. Therefore, the dominant wavelength of a star's light can tell us its surface temperature.
What temperature are blue stars?
The hottest stars are blue, with their surface temperatures falling anywhere between 10,000 K and 50,000 K.
Which star has the highest surface temperature?
Type O stars have the highest surface temperatures and can be as hot as 30,000 Kelvins.
Which star has highest temperature?
The hottest one measures ~210,000 K; the hottest known star. The Wolf-Rayet star WR 102 is the hottest star known, at 210,000 K.
What are the hottest stars called?
But the hottest known stars in the Universe are the blue hypergiant stars. These are stars with more than 100 times the mass of the Sun. One of the best known examples is Eta Carinae, located about 7,500 light-years from the Sun.
Is the star hotter than Sun?
The hottest stars have surface temperatures of 50,000 Kelvin degrees. The Sun surface is only 5800 Kelvin degrees, which means that there are hotter starts than the Sun.
What are the 7 different types of stars temperature?
There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M. O and B are uncommon, very hot and bright. M stars are more common, cooler and dim.
Is star hotter than Sun?
The hottest stars have surface temperatures of 50,000 Kelvin degrees. The Sun surface is only 5800 Kelvin degrees, which means that there are hotter starts than the Sun.
Is lava hotter than fire?
While lava can be as hot as 2200 F, some flames can be much hotter, such as 3600 F or more, while a candle flame can be as low as 1800 F. Lava is hotter than a typical wood or coal-buring fire, but some flames, such as that of an acetylene torch, is hotter than lava.
Is lava hotter than the Sun?
Lava is indeed very hot, reaching temperatures of 2,200° F or more. But even lava can't hold a candle to the sun! At its surface (called the "photosphere"), the sun's temperature is a whopping 10,000° F! That's about five times hotter than the hottest lava on Earth.
What does OH a fine girl kiss me mean?
Every student in introductory astronomy learns the mnemonic “Oh Be a Fine Girl/Guy, Kiss Me”, which is a way to remember the spectral classification of stars. Here's how it works: the color of a star is determined by its temperature, as I outlined previously.
How hot is blue lava?
10,830 °F Truly-blue lava would require temperatures of at least 6,000 °C (10,830 °F), which is much higher than any lava can naturally achieve on the surface of the Earth.
How hot is blue fire?
Blue flames usually appear at a temperature between 2,600º F and 3,000º F. Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood.
Would a diamond melt in lava?
To put it simply, a diamond cannot melt in lava, because the melting point of a diamond is around 4500 °C (at a pressure of 100 kilobars) and lava can only be as hot as about 1200 °C.
