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 are the factors that affect the luminosity of the star?
Its size and temperature.
If something is hotter and smaller does it give off a greater luminosity?
an increase in temperature or radius causes an increase in luminosity, assuming the other variable doesn't change. luminosity is the total energy output, rather than a measure of energy output against size.
What size does an object have to be in order to view an observable red shift from a distant object in space?
It has to be of sufficient size and luminosity to be visible through a telescope.

How many ways can you classify a square?
Several ways.By its size, orientation, colour, luminosity are some possible criteria.Several ways.By its size, orientation, colour, luminosity are some possible criteria.Several ways.By its size, orientation, colour, luminosity are some possible criteria.Several ways.By its size, orientation, colour, luminosity are some possible criteria.
What factor affects the luminosity of a star?
the size of a star
What are the factors that affect the luminosity of the star?
Its size and temperature.
What do stars have that depends on their size?
luminosity and temperature depend on their size but also on their mass
How do you measure the size of a black hole?
The size of a quasar can be inferred from the timescale of variations in its light output. Assuming that no signal can travel across the source faster than the speed of light, the time scale of the fastest variations sets an upper limit on the size of the quasar (i.e., size quals approximately the variation timescale times speed of light). An alternative method called 'reverberation mapping' monitors changes in the quasar's light output, then looks for these same changes in the light output from specific spectral lines. The delay times the speed of light gives the size of the quasar.
Are quasars much larger than stars?
Yes, a average quasar is the size of our solar system
Why do cool stars have greater luminosity than our sun?
They do not necessarily have greater luminosity, it depends on their size. Betelgeuse is cooler and brighter; a red dwarf is cooler and less bright.
If something is hotter and smaller does it give off a greater luminosity?
an increase in temperature or radius causes an increase in luminosity, assuming the other variable doesn't change. luminosity is the total energy output, rather than a measure of energy output against size.
How do size temperature and distance affect a star's magnitude or luminousity?
A star's real luminosity is proportional to the the square of its diameter, and more or less proportional to the fourth power of its absolute temperature. The star's apparent luminosity is proportional to its real luminosity. It is also inversely proportional to the square of the distance.
What size does an object have to be in order to view an observable red shift from a distant object in space?
It has to be of sufficient size and luminosity to be visible through a telescope.
