Red, yellow, and blue stars differ in size and luminosity due to their temperature and age. Red stars are cooler and larger, emitting lower energy light, while blue stars are hotter and smaller, emitting higher energy light. The differences in size and luminosity are also influenced by the stage of the star's life cycle, with younger stars typically burning brighter and hotter.

If a star is blue is its luminosity high or low?
Blue stars are very hot stars and so usually have high luminosity.
What are the temperatures of blue stars?
Between 11,000 and 25,000 Kelvin, or about 40,000 times the luminosity of the sun.
Do blue or yellow stars live longer?
Yellow stars usually have longer lifespans compared to blue stars. Blue stars burn hotter and faster due to their larger mass, causing them to have shorter lifespans. Yellow stars like our Sun have more stable energy production and can burn for billions of years.
What type of star has a high temperature and low luminosity in the HR diagram?
A blue dwarf star would have high temperature and low luminosity in the Hertzsprung-Russell (HR) diagram. Blue dwarf stars are in the lower left corner of the diagram, characterized by their high surface temperature and faint luminosity compared to other stars of similar temperature.
Temperature and brightness of stars are indicated by what?
Temperature of stars is indicated by their color, with blue stars being hotter than red stars. Brightness of stars is indicated by their luminosity, which is how much light a star emits.

What colour is the The European Union flag?
The European Union flag is a blue background with a circle of 12 yellow stars.

What is the color temperature and luminosity of a star for the big dipper?
The color temperature of most stars in the Big Dipper constellation is around 3000 to 6000 Kelvin, which would appear as white or slightly blue. The luminosity of these stars varies, but they are generally considered to be bright stars compared to the average stars in the night sky.
Are main sequence stars all alike in their luminosity and temperature?
No. Main sequence stars vary greatly in both temperature and luminosity. The least massive stars, red dwarfs, can have temperatures as low as 2,300 Kelvin and luminosity as low as 0.015% that of the sun. The most massive stars, which are blue in color can have temperatures as high as 50,000 Kelvin and may be hundreds of thousands times more luminous than the sun.
Are stars blue in colour?
Stars vary in color and may be red, orange, yellow, white, or blue. Blue stars are the hottest and among the brightest.
Are yellow stars hotter than blue stars?
No Blue stars are estimated to have an effective temperature of ≥ 30,000 K Blue-white stars are estimated to have an effective temperature of 10,000-30,000 K By contrast, yellow stars only have an effective temperature of 5,200-6,000 K. Even yellow-white stars are only 6,000-7,500 K
How do you get the blue rank award on Miniclip?
First you must get five yellow stars. After that you will go on to blue stars. Getting blue stars might be very hard.
How do blue stars differ from the red stars?
Blue stars are hot, and red stars are cold. You'd think it would be the other way around, but weirdly enough, it's not.
