What does colour of star indicates?
The color of a star indicates its temperature. Blue stars are hotter, while red stars are cooler. This is because hotter stars emit more energy in the blue part of the spectrum, while cooler stars emit more energy in the red part of the spectrum.
What color are cooler stars?
Cooler stars are typically red in color. These stars have lower surface temperatures compared to hotter stars, causing them to emit more red and infrared light.
Why are cooler stars red and hotter stars blue?
It may seem counter intuitive, but temperature defines the color of an object and the hotter an object is, the more its color will tend towards the left side of the color spectrum. As someone else said before on this site, thinking about heating a metal rod puts things in perspective. As you heat the rod, it glows red and than bluer in color as it heats up. Also, think about the hottest area of a flame--the flame is hotter at the point where it is blue in color rather than red.
Are all-stars the same as the sun?
No, some are hotter/cooler, some are more/less massive, but they all follow the same life processes.
One star is reddish and another is bluish Do you know anything about the relative temperatures of the two stars?
The reddish star is likely cooler than the bluish star. Red stars have lower surface temperatures compared to blue stars, with blue stars being hotter and more luminous. The color of a star is indicative of its temperature, with cooler stars appearing reddish and hotter stars appearing bluish.

Do dimmer stars live longer lives?
Dimmer stars generally are just farther away. Their brightness isn't necessarily a factor in how long they live. Their color is actually a better indicator. Yellow stars, like our own sun, burn cooler, and are therefore using their fuel more slowly. This will cause them to live longer. Stars with a red color are burning much hotter, and will therefore use up their fuel more quickly. Blue or white colored stars are burning hotter still!
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.

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.
What does color indicate in stars?
How hot or cool a star is. For example if a star is red, it's cooler. If a star is more blue, it's hotter.

What is the difference between red blue and white stars?
Red stars are cooler and emit more red light, blue stars are hotter and emit more blue light, while white stars fall in between and emit a broader spectrum of light. This color variation is due to differences in the stars' temperatures and compositions.
Do hot stars evolve more slowly than cool stars?
Hot stars evolve more quickly than cool stars. Hot stars have shorter lifespans due to their higher energy output, causing them to burn through their fuel more rapidly and evolve into different phases of stellar evolution more rapidly than cooler stars.
Does cooler magama flow more or less quickly than hotter magma?
Cooler magma flows slower than hotter magma.
