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 determines all the star's properties such as its temperature size brightness or luminosity and life span?
It's Mass
What factors affect the color of a star?
The temperature affects the color of a star.
What happens to the temperature of main sequence stars as the brightness increased?
Brightness is a value of luminosity verses distance as viewed from a point.From Earth, the luminosity of a star is it's apparent magnitude, whereas absolute magnitude is it luminosity as viewed from a set point (for stars this value is about 32 light years).Because of this a star can loose temperature but gain in diameter and appear brighter, in contrast a star can contract and thus shrink, but heat up and appear brighter.Brightness is related to temperature, not the other way around.
How would an increase in mass affect the basic properties of a star?
As mass increases It increases the surface temperature , luminosity, and radius.
What type of star has a high temperature and a high luminosity in the hr diagram?
White dwarfs.

What are super giants?
it is a very large star of high luminosity and low surface 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?
