How do you determine a stars luminosity?
To determine a star's luminosity is from size and temperature.
What factor affects the luminosity of a star?
the size of a star
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 does a stars luminosity measure?
Luminosity is the total amount of energy emitted by a star per second.
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.

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 diameter and luminosity of a main sequence star change when it becomes a giant or a supergiant?
In that case, both the star's diameter and its luminosity greatly increase.
What does a stars luminosity measure?
Luminosity is the total amount of energy emitted by a star per second.
How is a star's brightness described?
By it's luminosity.
How can you find the luminosity of a main sequence star?
it depends on the mass of the star.
What is the magnitude of a star as it appears in the sky called?
The Polar star is the star that is magnitude. This is a Luminosity star.
