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 the suns luminosty?
The Sun's luminosity is 3.846 × 10 ^26 Watts.
What is the luminosity class of the sun?
V
Who developed luminosity class system for stars?
Morgan and Keenan
What does the color of the ''oddball'' tell you?
Depends entirely on the class and luminosity of the oddball.
What does the color of the oddball tell you?
Depends entirely on the class and luminosity of the oddball.
What is the fifty-fourth star from the sun?
Based on what? Luminosity, distance or spectral class?
What does the the color of the oddball object tell you?

Depends entirely on the class and luminosity of the oddball.
Luminosity class IV objects are known as?
If you are referring to the Yerkes spectral classification, a Class IV star is known as a subgiant.
What star has the surface temperature of approximatly 9000 k and luminosity 1 to 20 times greater then the suns luminosity?
There are millions of stars that fit that description. On the Main Sequence a star needs a spectrum of type A to be around 9000 degrees, and 1 to 20 times the luminosity of the Sun means an absolute magnitude in the range 1.2 to 4.7. For example Sirius.
Why are o and b main sequence stars rare?
Simply, because they are the hottest and thus the most luminous.
