How do you determine a stars luminosity?
To determine a star's luminosity is from size and 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.
What are the factors that affect the luminosity of the star?
Its size and temperature.
What would be the absolute magnitude and color of a main sequence star with a luminosity of 100?
Absolute magnitude = -0.5Colour would depend on it's temperature.
What does a star's position in the main sequence tell you about that star?
It's luminosity and it's temperature.
What factors affect the color of a star?
The temperature affects the color of a star.

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 does a star's position in the main sequence tell you about that star?
It's luminosity and it's temperature.
What does the color of a star tell you about?
Its temperature, its mass, and its luminosity. Its size, nor distance have nothing to do with the colour of a star, bar maybe diffusion through additional materials when viewed from Earth.
Why would one star have a greater luminosity than another?
The luminosity of a star depends greatly on the star's mass. A more massive star has a larger pressure and temperature in its core; as a result, nuclear fusion will proceed at a faster rate.
What type of star has a high temperature and low luminosity in the HR diagram?
White dwarfs.
What type of star has a high temperature and high luminosity in the HR diagram?
White dwarfs.
What type of star has a high temperature and a high luminosity in the hr diagram?
White dwarfs.
