What is the order of stars from hottest to coldest?
Red stars are the coolest. Yellow stars are hotter than red stars. White stars are hotter than red and yellow. Blue stars are the hottest stars of all.
Which color of stars below has the highest surface temperature?
Red stars are cooler than the sun, with surface temperatures of 3,500 K for a bright red star and 2,500 K for a dark red star. The hottest stars are blue, with their surface temperatures falling anywhere between 10,000 K and 50,000 K. Stars are fuelled by the nuclear fusion reactions at their core.
Which star has highest surface temperature?
Type O stars
Type O stars have the highest surface temperatures and can be as hot as 30,000 Kelvins.
Which of the stars below is hottest?
O stars are the hottest, with temperatures from about 20,000K up to more than 100,000K. These stars have few absorption lines, generally due to helium. These stars burn out in a few million years. B stars have temperatures between about 10,000 and 20,000K.
Which star has the highest surface temperature?
Type O stars have the highest surface temperatures and can be as hot as 30,000 Kelvins.
What colors indicates a high temperature of stars?
Stars have different colors, which are indicators of temperature. The hottest stars tend to appear blue or blue-white, whereas the coolest stars are red.
What star has a low temperature and low luminosity?
What type of star has a low temperature and a low luminosity? red dwarf 11.
Which star is the coldest?
M stars are the coldest and O stars are the hottest in stellar classification. These stars are from the main sequence.
Which star has the hottest surface?
blue stars
The hottest stars are the blue stars. A star appears blue once its surface temperature gets above 10,000 Kelvin, or so, a star will appear blue to our eyes. So the hottest stars in the Universe are going to be a blue star, and we know they’re going to be massive.
Which star has the highest temperature?
The Wolf-Rayet star WR 102 is the hottest star known, at 210,000 K.
Which of the following stars has the hottest surface temperature?
What is the temperature of a white star?
Stars hotter than the Sun also look white. It isn’t until you reach a temperature of around 11,000 Kelvin before a star starts to look blue from our perspective. Most white stars are going to be hotter and more massive than our Sun.
What is the color and temperature of stars?
A star’s color is critical in identifying the star, because it tells us the star’s surface temperature in the black body radiation scale. The sun has a surface temperature of 5,500 K, typical for a yellow star. Red stars are cooler than the sun, with surface temperatures of 3,500 K for a bright red star and 2,500 K for a dark red star.
What spectral class is the Sun?
The full spectral class for the Sun is then G2V , indicating a main-sequence star with a surface temperature around 5,800 K.
