It's related to its surface area (proportional to the square of its diameter, or radius); as well as to the temperature (the total energy emitted is roughly proportional to the fourth power of the absolute temperature).Ultimately, of course, the luminosity depends on the energy production in the star's interior, which depends, among other things, on the star's core temperature.

If a star has a large luminosity and also a low surface temperature then it must have?
..... something wrong with it. Generally luminosity is related to temperature.
A star explosion which increases the star's luminosity to 1000 times that of a nova?
A Supernova. See related question
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.
Which star has the lowest luminosity?
A black dwarfSee related question for more details
What characteristics of a star are related to each other?
Mass and gravity are directly connected, and luminosity is closely related to mass.
What is a Polaris star luminosity?
The main star in the Polaris system has a luminosity which is 2500 times that of the Sun.
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 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.
