There are 2 main factors: the size of the star and its surface temperature.
A larger size means a larger surface area to emit light.
A higher surface temperature increases the energy emitted.
Seen from Earth, the brightness of a star depends on how far away the star is as well as its actual luminosity.
What else can I help you with?
How does luminosity affect the CHZ?
Luminosity affects the habitable zone (CHZ) by determining the distance at which a planet would need to be from a star to have the right temperature for liquid water to exist on its surface. Stars with higher luminosity would have habitable zones farther out, while stars with lower luminosity would have habitable zones closer in. This means that the size and location of the CHZ around a star depend on its luminosity.
What is a sentence with luminosity?
The stars shone with a luminosity reminiscent of diamonds on black velvet .
What is the luminosity of a white dwarf star?
The luminosity of a white dwarf star can vary depending on its mass and age, but typically ranges from about 0.001 to 0.1 times the luminosity of the Sun. These stars are small and dense, with surface temperatures ranging from 8,000 to 100,000 Kelvin, which affects their brightness.
Are The most common type of stars are low luminosity stars?
Yes. Around 76% of the stars are low luminosity stars.
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
What factor affects the luminosity of a star?
the size of a star
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.
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.
Why are most visual binary stars of low luminosity?
Most visual binary stars are of low luminosity because they are often close together and both stars have similar masses, resulting in them being fainter than single stars of the same age. Additionally, the companion stars in these binary systems may not be large or hot enough to emit high levels of light.
Who developed luminosity class system for stars?
Morgan and Keenan
