The period of this variation in luminosity is related to the star's true brightness,known as its absolute magnitude.
The Sun has an absolute magnitude of +4.8- about half way between the two extremes.
Metallicity has a positive correlation with the absolute magnitude(luminosity) of a galaxy.
Astronomers use absolute magnitude to express the intrinsic brightness of a star.
Expressing this assumption in astronomical parlance,we would say that quasars have the same absolute magnitude, M.
The difference between the relative and absolute magnitude, the distance modulus, yields this estimate of the distance.
The absolute magnitude was estimated at -4.5, approximately 40 times fainter than the primary at visual wavelengths.
According to observations, 2013 US3 has an absolute magnitude of 21.3 and an estimated diameter between 100 and 330 meters.
Its absolute magnitude is 18 times greater than β Cas, although it is located farther away from the Sun(228 light years versus 54).
The brightest novae all appear to have the about the same absolute magnitude, so they can be used as a standard candle as well.
Since the sun's absolute magnitude is 4.83, it means that the quasar is over 4 trillion times more luminous than the Sun at visible wavelengths.
A standard candle is a bright object for which we think that we know how bright it is, or in other words,we know its absolute magnitude.
A supergiant star might have an absolute magnitude of -8 whereas a dim red dwarf might have an absolute magnitude of +16.
From galaxy to galaxy these brightsuper giants appear to have about the same absolute magnitude, so they too represent a standard candle.
Since we know the absolute magnitude of type Ia supernovae, we can use them to measure extremely large distances, often leap-frogging over other methods.
We can use the mean distance andmean apparent magnitude to determine the absolute magnitude of any member of the sample from the above equation.
Therefore, if we know the absolute magnitude of a particular star, we can find its distance by measuring its apparent magnitude and using the above distance formula.
I began with the simple assumption that quasars have the same absolute magnitude, but within the paradigm of cosmological redshifts, quasar luminosities are not all the same.
