What is a star of high luminosity called?
red giant
If a star has a large luminosity and also a low surface temperature then it must have?
If a star has a large luminosity and a low surface temperature, it must have a large surface area to compensate for the low temperature and still emit a high amount of energy. This would make the star a red supergiant, a type of star that is both luminous and cool at the same time.
What are super giants?
it is a very large star of high luminosity and low surface temperature.....=)))))
The amount of light a star gives off is called what?
its called magnitude or luminosity. :) hope it helped you.
If a star is blue is its luminosity high or low?
Blue stars are very hot stars and so usually have high luminosity.
What is the magnitude of a star as it appears in the sky called?
The Polar star is the star that is magnitude. This is a Luminosity star.
What is the brightness of a star as it appears called?
it's luminosity
Why does a cool distant supergiant star such as betelgeuse have a high luminosity?
Betelgeuse, a cool distant supergiant star, has a high luminosity primarily due to its large size and surface area. Despite its relatively low temperature, its vast volume allows it to emit a significant amount of energy. The combination of its expansive radius and the Stefan-Boltzmann Law, which states that a star's luminosity increases with the fourth power of its temperature, results in Betelgeuse's impressive brightness. Thus, even with a lower temperature, its sheer size compensates, leading to high luminosity.
What is a measure of the total energy radiated by the star in one second called?
A star's luminosity is the measure of the total energy radiated by the star in one second.
What type of star has a high temperature and a high luminosity in the hr diagram?
White dwarfs.
What type of star has a high temperature and high luminosity in the HR diagram?
White dwarfs.
What type of star has a low temperature buts high luminosity?
A red supergiant star is characterized by a low surface temperature but high luminosity. These stars are typically in a late stage of stellar evolution, having expanded significantly and cooled after exhausting their hydrogen fuel. Despite their lower temperatures, their large size allows them to emit a substantial amount of light, resulting in high luminosity. Examples include stars like Betelgeuse and Antares.
