Large stars are hotter than smaller stars primarily due to their greater mass, which leads to higher gravitational pressure in their cores. This increased pressure raises the core temperature, facilitating more intense nuclear fusion reactions. As a result, large stars burn their nuclear fuel at a much faster rate than smaller stars, generating higher temperatures and luminosities. Additionally, the greater energy output from these reactions contributes to their overall heat.
What else can I help you with?
True or false Red stars are hotter than whittish- blue stars?
False. Blue giants(or hypergiants) are hotter than Red giant stars. White dwarves are also hotter but they are smaller than blue giants. (As is implied by the name.)
What is a clue to a stars temperature?
Its colour. White stars are hotter than blue stars which are hotter than yellow which are hotter than orange, which are hotter than red.
Are all bright stars the same temperature?
No, bright stars can have different temperatures. The color of a star typically indicates its temperature, with blue stars being hotter than red stars. Brightness is influenced by both temperature and size; a larger, cooler star could appear brighter than a hotter, smaller star.
Are stars cooler than the sun brighter or dimmer?
Stars can be both cooler and brighter or hotter and dimmer than the Sun, depending on their size and age. Generally, larger and younger stars are hotter and brighter than the Sun, while smaller and older stars can be cooler and dimmer.
Is a blue star hotter than a red giant?
blue stars are hotter

Why do bigger stars die more quickly?
Bigger stars get hotter, and use up their fuel much faster than smaller stars.
Are all bright stars the same temperature?
No, bright stars can have different temperatures. The color of a star typically indicates its temperature, with blue stars being hotter than red stars. Brightness is influenced by both temperature and size; a larger, cooler star could appear brighter than a hotter, smaller star.
Why are the stars smaller than the moon?
Stars are smaller than the moon because they are further away. They're not actually smaller, its just because they are so far away. Stars are actually very large.
How does the HR diagram explain why some smaller cooler stars are brighter than larger hotter stars?
In terms of absolute magnitude, a larger hotter star will necessarily be more luminous than a smaller cooler star. However, if a smaller cooler star is much closer to us than a larger hotter star, it may appear to be brighter. None of this has anything to do with the HR diagram.
Are stars cooler than the sun brighter or dimmer?
Stars can be both cooler and brighter or hotter and dimmer than the Sun, depending on their size and age. Generally, larger and younger stars are hotter and brighter than the Sun, while smaller and older stars can be cooler and dimmer.
Is the sun hotter or cooler than red and blue stars?
The sun is hotter than red stars but cooler than blue stars,
Why are stars hotter than the surrounding area?
stars are hotter than the surrounding area because the surrounding area isn't so hot.
Which is hotter red stars or whitish - blue stars?
White Dwarves and Blue giants are both hotter than Red giant stars.
Is a blue star hotter than a red giant?
blue stars are hotter
Is the star Betelgeuse hotter than our sun?
No. The sun is actually hotter than Betelgeuse, but much smaller.
