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.
How much Mass would the luminosity of 3160 be?
To find the mass corresponding to a luminosity of 3160 times that of the Sun, we can use the mass-luminosity relationship for main-sequence stars, which states that luminosity (L) is proportional to mass (M) raised to approximately 3.5 power (L ∝ M^3.5). Rearranging this gives us M ≈ (L/L_sun)^(1/3.5), where L_sun is the luminosity of the Sun. Plugging in 3160 for luminosity, the mass would be roughly 15.5 times the mass of the 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 3.8261026?
3.826x1026 is the luminosity, in Joules/second, of our sun.
Does Rigel have a higher luminosity and a lower temperature the the sun?
No.
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.
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.
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.
