What is the luminosity class of the sun?
V
What is the luminosity of Deneb?
Deneb has a luminosity (apparent magnitude) of 1.25. However, in bolometric luminosity (solar units) Deneb is 54,000, whereas our Sun is 1.
Why does the sun have a luminosity of 1?
It really depends on the units used. Sometimes the Sun is used as a comparison for the brightness of other stars, or even galaxies - in this case, the Sun's luminosity is arbitrarily defined as 1, and a star that is 10 times brighter will have luminosity 10, for example. However, if you use other units, for example watts, you get quite different numbers (3.846×1026 watts for the Sun, according to the Wikipedia).
Does Rigel have a higher luminosity and a lower temperature the the sun?
No.
According to the Hertzsprung Russell Diagram what is the luminosity of the Sun?
The Sun is the main basis for many stellar parameters. A far as luminosity goes - it is 1.
How is star luminosity measured?
A star's luminosity is measured according to the relevance to the sun. Basically for example, if a star is 8,300 degrees Celsius and has a luminosity of 0.001; the luminosity is compared to the sun.

What is a Polaris star luminosity?
The main star in the Polaris system has a luminosity which is 2500 times that of the Sun.
Does Rigel have a higher luminosity and a lower temperature the the sun?
No.
What is 3.8261026?
3.826x1026 is the luminosity, in Joules/second, of our sun.
Why is the suns luminosity 1?
A solar luminosity is equal to the current luminosity of the Sun, which is 3.839 × 1026 W, or 3.839 × 1033 erg/s.So dividing one solar luminosity with the Suns luminosity gives 1.Also it is a lot easier talking about a luminosity of 1 rather than 3.838 x 1026 W, the same way astronomers use 1 AU to mean 150,000,000km.
What is Zeta Draconis's luminosity compared to the sun?
Zeta Draconis is a binary star system where one of the stars, Zeta Draconis A, has a luminosity around 14 times that of the sun.
Why is alpha centauri as luminosity 1.6 times that of the sun?
Alpha Centauri is as luminosity is 1.6 times that of the sun because it fuses hydrogen and helium in its core at a higher rate.
According to the Hertzsprung Russell Diagram what is the luminosity of the Sun?
The Sun is the main basis for many stellar parameters. A far as luminosity goes - it is 1.
What is the luminosity of Betelgeuse?
Betelgeuse has a luminosity that is around 100,000 times that of the Sun. It is classified as a red supergiant star and is one of the brightest stars visible to the naked eye. Despite its high luminosity, Betelgeuse is also known for its variability in brightness.
