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.
Which star has a surface temperatureapproximately 9000 K and luminosity off about 1 to 20 times greater than the signs luminosity?
A star with a surface temperature of approximately 9000 K and a luminosity between 1 to 20 times that of the Sun is likely a type A main-sequence star. These stars are known for their blue-white color and burn hydrogen in their cores. An example of such a star is Alpha Centauri A, which exhibits characteristics consistent with this temperature and luminosity range.
What type of star has a high temperature and low luminosity in the HR diagram?
A blue dwarf star would have high temperature and low luminosity in the Hertzsprung-Russell (HR) diagram. Blue dwarf stars are in the lower left corner of the diagram, characterized by their high surface temperature and faint luminosity compared to other stars of similar temperature.
What is the surface temperature of the star gamma pyxidis?
The surface temperature of the star Gamma Pyxidis, a B-type main-sequence star, is approximately 20,000 to 25,000 Kelvin. This high temperature gives it a blue hue and contributes to its classification as a hot star. Its significant temperature also results in a substantial luminosity, making it one of the brighter stars in its region.
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 information is needed to plot a star on the H-R diagram?
To plot a star on the H-R diagram, you need the star's luminosity (or absolute magnitude) and its surface temperature (or spectral type). These two properties allow you to place the star accurately on the diagram based on its position relative to other stars.
Does An HR diagram plots a stars luminosity and surface temperature?
Yes, an HR diagram plots a star's luminosity (brightness) against its surface temperature, also known as color or spectral type. This graph shows the relationship between these two characteristics for different stars, allowing astronomers to classify and study them.

What is the surface temperature of the star Algenib?
Algenib, also known as Gamma Pegasi, is a B-type main-sequence star with an approximate surface temperature of around 12,000 to 15,000 Kelvin. This high temperature contributes to its blue-white color and significant luminosity. As a result, Algenib is much hotter and more massive than our Sun.
What type of star has a low surface temperature and a high luminosity?
Yellow stars with low strength hydrogen lines. This type includes the modern "G" and "K" types and the old "F" type, and among the stars of this type: the sun and arthropods.
