Luminosity is the total amount of energy emitted by a star per second.
What else can I help you with?
What is a sentence with luminosity?
The stars shone with a luminosity reminiscent of diamonds on black velvet .
Are The most common type of stars are low luminosity stars?
Yes. Around 76% of the stars are low luminosity stars.
How do you determine a stars luminosity?
To determine a star's luminosity, one can measure its apparent brightness as seen from Earth and correct for distance. Using this information along with the star's surface temperature, one can apply the Stefan-Boltzmann law to calculate the star's luminosity. This process allows astronomers to compare the intrinsic brightness of stars regardless of their distance from Earth.
If a star is blue is its luminosity high or low?
Blue stars are very hot stars and so usually have high luminosity.
What process of losing their outer layer causes stars to lose?
luminosity or brightness
What two characteristics are stars classified by?
They are classified by the amount of Light they give off, and their temperature.
How do astronomers use luminosity?
Astronomers use luminosity to measure the total amount of energy a star emits in all directions. By knowing a star's luminosity, astronomers can calculate its distance, size, and temperature. Luminosity helps astronomers understand the life cycle of stars and their evolution.

What do the terms luminosity and magnitude mean in describing stars?
Luminosity is the total amount of energy a star emits in a certain amount of time, while magnitude is a measure of a star's brightness as observed from Earth. Luminosity is an intrinsic property of a star, whereas magnitude is affected by the distance between the star and the observer. Lower magnitude values correspond to brighter stars.
Which of the following luminosity classes refers to stars on the main sequence?
The basic luminosity classes are: I for supergiants, III for giants, and V for main-sequence stars.
How do astronomers measure stellar luminosity?
The reference that astronomers use to compare the luminosity of other stars is the sun's luminosity. The luminosity is denoted in multiples of the sun's luminosity. For example, the luminosity of the star Sirius is 25 times the luminosity of the sun.
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.
