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.)


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.


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.


Does the color of the star depends on its size?

Yes, the color of a star is determined by its temperature, with hotter stars appearing blue/white and cooler stars appearing red. Generally, larger stars tend to be hotter and appear bluer, while smaller stars are cooler and appear redder.


Why are large stars hotter than smaller stars?

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.

Hotter.


Why do bigger stars die more quickly?

Bigger stars get hotter, and use up their fuel much faster than smaller stars.

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.
