What is a sentence with luminosity?
The stars in the night sky shine with a remarkable luminosity.
How do you determine a stars luminosity?
To determine a star's luminosity is from size and temperature.

What is a Subdwarf star?
A star with luminosity class VI under the Yerkes Spectral Classification System. They have luminosity 1.5 to 2 magnitudes lower than main-sequence stars of the same spectral type.
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 process of losing their outer layer causes stars to lose?
luminosity or brightness
What does a stars luminosity measure?

What is the stars intrinsic brightness called?
Luminosity.
