If a star has a large luminosity and also a low surface temperature then it must have?
..... something wrong with it. Generally luminosity is related to temperature.
What is a sentence with luminosity in it?
I was enthralled by the luminosity of the deep water jellyfish.
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.
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 is the luminosity of the sun?
The absolute luminosity is about 3.839×1026 W, or 3.839×1033 erg/second. The comparative luminosity of an astronomical object is based on the Sun, so it has a relative luminosity of 1.
Si unit for light intensity?
Light intensity is also known as luminosity. Candela is the si unit
Why would two stars have different sizes and tempertes but same luminosity?
The luminosity depends on what stage of its life cycle the star is in. Also, the apparent luminosity depends on the distance from earth.

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.
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.
How do you measure the distance to a cepheid?
Cepheids have a certain relationship between their period, and their absolute luminosity. Thus, their absolute luminosity can be determined. Comparing this with their apparent luminosity allows us to calculate their distance.Cepheids have a certain relationship between their period, and their absolute luminosity.

What do stars have that depends on their size?
luminosity and temperature depend on their size but also on their mass
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.
Who is the guy in the Luminosity commercial?
Michael Emerson is in the Luminosity commercial.
What is luminosity of the Rigel?
Rigel has a luminosity of 117,490 solar luminosities.
