Does apparent magnitude refer to real luminosity?
No. Apparent magnitude (or luminosity) means how bright a star (or other object) looks to us; absolute magnitude (or luminosity) refers to how bright it really is.
What is a sentence with luminosity in it?
I was enthralled by the luminosity of the deep water jellyfish.
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.
What is a sentence with luminosity?
The stars in the night sky shine with a remarkable luminosity.
Which means the same as luminosity?
Absolute magnitude.
What word means the same as luminosity?
Caution
Does apparent magnitude refer to real luminosity?
No. Apparent magnitude (or luminosity) means how bright a star (or other object) looks to us; absolute magnitude (or luminosity) refers to how bright it really is.
What is the luminosity of gamma ceti?
It is a triple star system. Therefore every single star has different luminosity. However, as a whole the system is seen from earth at an appereant magnitude of 3.47, which means only %6 luminosity of the star vega.
What is a sentence with luminosity in it?
I was enthralled by the luminosity of the deep water jellyfish.
What is the root word for the word luminosity?
The root word is lum. It means light or bright.

What is the root word of luminosity?
The root word of "luminosity" is "lumin," which comes from the Latin word "lumen" meaning light.
Why are dwarf stars dim?
Dwarf stars are dim because they are small, so their luminosity (amount of emitted energy) is low compared to other stars, and low luminosity means more dimness.
What is the difference between a star's luminosity and brightness?
The difference between apparent brightness and luminosity is that apparent brightness means that a star may appear to be bright, but only looks bright because of the relatively closeness a star is to earth. Luminosity is used by astronomers and refers to the power output of a star. Apparent Brightness means a star may appear to be very bright but only look that way because it is relatively close to Earth. Luminosity just refers to the power output of a star.

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.
