Why does the red yellow and blue stars differ in size and luminosity?
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.
Why does Rigel shine as bright as Betelgeuse even though Rigel is much smaller than Betelgeuse?
Rigel appears as bright as Betelgeuse because it is hotter and more luminous, even though it is smaller. The luminosity of a star depends on both its temperature and size, so a hotter, more luminous star can shine as brightly as a larger, cooler star.
How is it possible for white dwarfs of have a lower luminosity than the sun even though the sun is much cooler than the white dwarfs?
Because luminosity is a measure of brightness over distance. Also white dwarfs are a hundred times smaller than the Sun. Most white dwarfs are a long way away and thus are difficult to see.
Is the star Betelgeuse hotter than our sun?
No. The sun is actually hotter than Betelgeuse, but much smaller.
Why does rigel shine as brightly as betelgeuse even though rigel is much smaller than betelgeuse?
Rigel appears as bright as Betelgeuse because it is closer to Earth than Betelgeuse, even though Rigel is smaller and less luminous. The brightness of a star is determined by both its luminosity and distance from Earth, so a smaller, closer star can appear just as bright as a larger, more distant one.
What luminosity of a star is related to its?
The luminosity of a star is related to its surface temperature and size. Hotter stars with larger surface areas tend to have higher luminosities, while cooler stars with smaller surface areas have lower luminosities.
What describes the relationship between the luminosity of two stars that have the same radius?
The star that is hotter will have a higher luminosity.
What correctly describes the relationship between the luminosity of two stars that have the same radius?
The star that is hotter will have a higher luminosity.

Which star is giving off more light?
The star that gives off more light is likely larger and hotter than the other star. The brightness of a star is directly related to its size and temperature, with larger and hotter stars emitting more light.
Smaller stars tend to be?
Hotter.
How is it possible for white dwarfs of have a lower luminosity than the sun even though the sun is much cooler than the white dwarfs?
Because luminosity is a measure of brightness over distance. Also white dwarfs are a hundred times smaller than the Sun. Most white dwarfs are a long way away and thus are difficult to see.
What are the factors that contribute to determining the luminosity scores of celestial objects?
The factors that contribute to determining the luminosity scores of celestial objects include their size, temperature, and distance from Earth. Larger and hotter objects tend to have higher luminosity scores, while objects that are closer to Earth appear brighter.
Why are dwarf stars dim?
Dwarf stars are dim because they are smaller and cooler than other types of stars. Their lower temperature and smaller surface area result in less light being emitted compared to larger, hotter stars. This makes them appear dimmer when observed from a distance.
Is 50 degrees hotter on a celsius or on a Fahrenheit and why?
50 degrees hotter is greater on the Fahrenheit scale because each degree on the Fahrenheit scale is smaller than each degree on the Celsius scale, making the difference more significant in Fahrenheit.
Is the star Betelgeuse hotter than our sun?
No. The sun is actually hotter than Betelgeuse, but much smaller.
