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. After a star sheds its 'skin' the only thing that is left is the white hot core, which will eventually dim to a brown dwarf which is nothing but the cool charred remains of the white dwarf and will give off little to no light.

What color is an O star?
An O star is typically blue in color, and is one of the hottest types of stars with surface temperatures exceeding 30,000 K. The color of a star is a result of its temperature, with hotter stars appearing blue and cooler stars appearing red.
The color of the star can be indication of the?
The star's temperature. The more blue the star is the hotter it is. Pure blue stars get up to around 18,000 k. The more red the star is the cooler it is. Pure red stars can get up to around 2,500 k. White, yellowish color stars are in the middle.
Is a blue star a baby star?
Not necessarily. Blue stars can be young, hot, and massive, but not all blue stars are newly formed. Blue stars can exist at different stages of their life cycle, depending on their mass and the ways in which they are evolving.
Can a yellow star be bigger than a blue?
Yes, the color of a star is determined by its temperature, with blue stars being hotter than yellow stars. The size of a star is determined by its mass, age, and stage of life, so a yellow star can potentially be bigger than a blue star depending on these factors.
Which is hotter a blue star or a red star and why?
A blue star is hotter than a red star. The color of a star indicates its surface temperature, with blue stars having temperatures exceeding 10,000 degrees Celsius, while red stars typically have temperatures around 2,500 to 3,500 degrees Celsius. The higher energy output and temperature of blue stars result from their larger mass and more intense nuclear fusion processes occurring in their cores.
When a star changes from blue to red what happens to the surface temperature?
The temperature is lowered.
Suppose you see two stars a blue star and a red star what can you conclude about the two stars?
The color of a star is influenced by its temperature, with blue stars being hotter than red stars. Therefore, you could conclude that the blue star is hotter than the red star. Additionally, blue stars typically have shorter lifespans than red stars.
Is a blue star hot?
All stars are hot. Blue stars are the hottest.
What really is a blue star?
A blue star is a type of star that is hot, massive, and emits predominantly blue light. These stars have temperatures of around 10,000 to 40,000 degrees Celsius, causing them to appear blue in color. Blue stars are typically young and have short lifespans compared to other types of stars.
What color star is hotter a red star of a blue star?
A blue star is hotter than a red star. Blue stars have higher surface temperatures, typically exceeding 10,000 Kelvin, while red stars have lower surface temperatures, usually below 4,000 Kelvin. The color of a star is an indication of its temperature, with blue stars being the hottest and red stars being the coolest.
What can be said with certainty about a red star and a blue star?
A red star is cooler and has a lower temperature compared to a blue star, which is hotter. Red stars are typically older, while blue stars are younger. The color of a star is determined by its surface temperature, so these differences in characteristics between red and blue stars are consistent.
What is the name the hottest star?
blue stars are the hottest stars.
Why do stars turn blue?
Stars are blue because of their age and temperature. Blue is an indication of a young HOT star, when reddish color means the star is aging
Which one of the star is hottest?
If you mean "What is the hottest star". 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.
Is a blue star called a blue dwarf?
No. A blue dwarf is a theoretical class of star. The known blue stars are not blue dwarfs.
Which star is the brightest red or blue why?
The brightest stars are typically blue because they are hotter and emit more light compared to red stars. Blue stars have higher surface temperatures, which causes them to shine brighter than red stars.
The color of hotest star?
white dwarf
