A star that has high temperature and low luminosity is typically classified as a white dwarf. White dwarfs are the remnants of stars that have exhausted their nuclear fuel and shed their outer layers, resulting in a hot but relatively small core. Despite their high temperatures, their low luminosity is due to their small size and limited surface area for emitting light. As they cool over time, they gradually become less luminous.

What type of star has a high temp and high luminosity?
A star with high temperature and high luminosity is typically classified as a massive main sequence star, often of spectral type O or B. These stars have surface temperatures exceeding 30,000 Kelvin and emit vast amounts of energy due to their size and nuclear fusion processes. They are relatively rare and have short lifespans, often ending in supernova explosions.
What type of star has high temp and a high luminosity On the H-R diagram?
On the Hertzsprung-Russell (H-R) diagram, stars that have high temperature and high luminosity are typically found in the upper left quadrant, classified as O-type or B-type stars. These stars are massive and emit a significant amount of energy due to their high temperatures, often exceeding 30,000 Kelvin. They are characterized by their blue or blue-white colors and have relatively short lifespans compared to less massive stars.
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.
Which type of star best obey mass-luminosity relation?
Main sequence stars best obey the mass-luminosity relation. This empirical relation states that there is a direct relationship between a star's mass and its luminosity. In general, the more massive a main sequence star is, the more luminous it will be.
What is the Luminosity of the star albali?
Albali, also known as Epsilon Aquarii, is a K-type giant star with a luminosity approximately 140 times that of the Sun. Its brightness is a result of its larger size and advanced stage in stellar evolution. The exact luminosity can vary slightly based on different measurements, but it generally falls within this 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.

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 type of star has a low temperature buts high luminosity?
A red supergiant star is characterized by a low surface temperature but high luminosity.

What is the color of the Lambda type of star in the Aries constellation?
Lambda Arietis is a double star in the northern constellation of Aries. It is comprised of a yellow-white primary star ( spectral type F, luminosity class V) and a yellow secondary star (spectral type G, luminosity class V). To the naked eye these appears yellow-white.
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.
Which type of star best obey mass-luminosity relation?
Main sequence stars best obey the mass-luminosity relation. This empirical relation states that there is a direct relationship between a star's mass and its luminosity. In general, the more massive a main sequence star is, the more luminous it will be.
