Which star has the highest temperature red or blue?
Astronomers also classify stars according to color. The color of a star shows its surface temperature. Blue stars are the hottest, followed by white, yellow, orange, and red. The sun is a yellow star.
Which star has the highest temperature?
The Wolf-Rayet star WR 102 is the hottest star known, at 210,000 K.
Which color of the star has the highest temperature?
Blue stars
White stars are hotter than red and yellow. Blue stars are the hottest stars of all.
What type of star has a high temperature and a high luminosity?
Blue Giants
What type of star has a high temperature and a high luminosity? Blue Giants 19.
What color is stars temperature?
Temperature – cooler stars are red, warmer ones are orange through yellow and white. The hottest stars shine with blue light.
What is the temperature of blue stars?
The hottest stars are blue, with their surface temperatures falling anywhere between 10,000 K and 50,000 K.
What is the temperature of a blue star?
Which of the following stars has the highest temperature blue Giant?
Rigel
Blue supergiants are supergiant stars (class I) of spectral type O. They are extremely hot and bright, with surface temperatures of between 20,000 – 50,000 degrees Celsius. The best known example is Rigel, the brightest star in the constellation of Orion.
Which stars have the highest luminosity?
List of stars more luminous than any closer star
| Name | Constellation | Bolometric luminosity (Solar lum.) |
|---|---|---|
| Sun | 1 | |
| Alpha Centauri A | Centaurus | 1.519 |
| Sirius | Canis Major | 25.4 |
| Vega | Lyra | 40.12 |
Which type of star has the greatest luminosity?
The stars in group C are even more luminous than the giants. These are the supergiants, the largest of stars with extremely high luminosities. A red supergiant such as Betelgeuse would extend beyond the orbit of Jupiter if it replaced the Sun in our solar system.
Why are some stars red and some blue?
The color of a star is linked to its surface temperature. 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.
Is a blue star hotter than a Red Star?
Then a blue star is HOTTER than a RED star. The temperature of a blue star is 40000 Kelvin degrees, the temperature of a red star is 3500 Kelvin. Red stars are cooler.
What is the color of the stars?
This makes the cooler stars appear red and the stars with the higher temperatures appear blue or white. From cool to hot, the colors can appear red, orange, yellow, green and blue. If you remember the colors of the rainbow, you will see that these are in the same order. There is another important factor that can alter a stars color.
What is the temperature of a red star in Kelvin?
Then a blue star is HOTTER than a RED star. The temperature of a blue star is 40000 Kelvin degrees, the temperature of a red star is 3500 Kelvin. Red stars are cooler. They are red because they emit red light, which is lower in energy than blue light.
What color of light does the hottest star emit?
Just look at the electromagnetic spectrum. You will see that blue has the highest energy in the visible spectrum, then comes yellow, and lowest comes red. Lower wavelength means higher energy. Now the stars that emit the most energy (aka hottest) would obviously emit light with highest energy, which is blue.
