Why must a star's parallax be known before you can find the luminosity?

What must be known is the distance. And the most accurate method to measure the distance of nearby stars is the parallax - but this method won't work for stars that are far away.

Are The most common type of stars are low luminosity stars?
Yes. Around 76% of the stars are low luminosity stars.
What is a sentence with luminosity?
The stars in the night sky shine with a remarkable luminosity.
The apparent shift in the position of nearby stars when compared to distant stars is?
Doug Fany answer: Parallax
Distance to nearby stars can be determined from?
stellar parallax
How do you determine a stars luminosity?
To determine a star's luminosity is from size and temperature.

How do you measure the distance to a star?
Several methods exist. A fairly obvious one is the parallax method - while Earth moves around the Sun, it changes its position by about 300 million km.; this will change the apparent position of nearby stars. For star clusters or galaxies that are further away, several "standard candle" methods exist, which basically consist of comparing the real luminosity of objects that have a known brightness (like certain types of stars) with their apparent luminosity.

How did scientists gather information about stars?
Scientista started to gather information by observing the stars and learnt from here. First they used parallax to get the distance, then the apparent brightness, but after a while they can get luminosity, size/mass, what fuel they use (eg.helium), and then from that the learnt about the starts lifetime.

Method to measure the distance to nearby stars directly?

If a star is blue is its luminosity high or low?
Blue stars are very hot stars and so usually have high luminosity.
Why are most visual binary stars of low luminosity?
If the binary stars were of too high luminosity it would be impossible to distinguish the two through vision alone. Therefore most visual binary stars are of low luminosity.
What can parallax be used to determine about a star?
Parallax is a method used to find the distances of stars.
What process of losing their outer layer causes stars to lose?
luminosity or brightness
