Measurements of a binary star system are required to determine what property of the stars?
Luminosity
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.
If a star is blue is its luminosity high or low?
Blue stars are very hot stars and so usually have high luminosity.
What process of losing their outer layer causes stars to lose?
luminosity or brightness

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 process of losing their outer layer causes stars to lose?
luminosity or brightness
What does a stars luminosity measure?
Luminosity is the total amount of energy emitted by a star per second.
What is the stars intrinsic brightness called?
Luminosity.
Which of the following luminosity classes refers to stars on the main sequence?
The basic luminosity classes are: I for supergiants, III for giants, and V for main-sequence stars.
What describes the relationship between the luminosity of two stars that have the same radius?
The star that is hotter will have a higher luminosity.
Why are dwarf stars dim?
Dwarf stars are dim because they are small, so their luminosity (amount of emitted energy) is low compared to other stars, and low luminosity means more dimness.
What correctly describes the relationship between the luminosity of two stars that have the same radius?
The star that is hotter will have a higher luminosity.
