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.
What is the luminosity of the sun?
The luminosity of the Sun is approximately 3.8 x 10^26 watts, which means it is emitting this amount of energy every second. This energy output is generated through nuclear fusion reactions in the Sun's core.
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 a sentence with luminosity?
The stars shone with a luminosity reminiscent of diamonds on black velvet .
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.
How does the luminosity of a blackbody vary with its surface temperature?
Both the absorption and the luminosity of a blackbody in equilibrium increase in magnitude with increasing temperature, and the spectral distribution of the luminosity increases in frequency (decreases in wavelength).
How does luminosity affect the CHZ?
Luminosity affects the habitable zone (CHZ) by determining the distance at which a planet would need to be from a star to have the right temperature for liquid water to exist on its surface. Stars with higher luminosity would have habitable zones farther out, while stars with lower luminosity would have habitable zones closer in. This means that the size and location of the CHZ around a star depend on its luminosity.
What is a sentence with luminosity in it?

What is the luminosity of the sun?
The luminosity of the Sun is approximately 3.8 x 10^26 watts, which means it is emitting this amount of energy every second. This energy output is generated through nuclear fusion reactions in the Sun's core.
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?
Lum is the root word. This root word means light or bright.

What is the difference between a star's brightness and luminosity?
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.
