Luminosity is the total amount of energy emitted by a star per second.
Waldo Ledner
A star's luminosity measures the total amount of energy it emits per unit of time across all wavelengths. It provides information about the star's intrinsic brightness and power output. Luminosity is an important characteristic used to classify and study stars.
The stars in the night sky shine with a remarkable luminosity.
No, the most common type of stars are actually low mass red dwarf stars. These stars are smaller and cooler than the Sun, resulting in lower 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.
Blue stars are very hot stars and so usually have high luminosity.

They are classified by the amount of Light they give off, and their temperature.
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.

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.
The intrinsic brightness of a star is called its absolute magnitude. This is a measure of how bright a star would appear if it were located at a standard distance of 10 parsecs (32.6 light-years) from Earth.
Luminosity class V refers to stars on the main sequence. These stars are actively fusing hydrogen into helium in their cores and represent the majority of stars, including our sun.
The star that is hotter will have a higher luminosity.
