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 HR diagram based on?
The Hertzsprung-Russell (HR) diagram is based on plotting a star's luminosity against its temperature or spectral type. This diagram helps astronomers classify stars based on their evolutionary stage and enables them to study relationships between a star's properties such as temperature, luminosity, and size.
What elements are in the star Alrisha?
Alrisha, also known as Alpha Piscium, is a binary star system composed of two main-sequence stars. The primary star is a spectral type A5V star, while the secondary star is a spectral type F0V star. Both stars are relatively bright and contribute to the overall luminosity of Alrisha.
What is the main sequence on the Hertzsprung-Russell diagram?
The main sequence on the Hertzsprung-Russell diagram represents the stage in a star's life when it is undergoing nuclear fusion of hydrogen into helium in its core. Stars spend the majority of their lifetime on the main sequence, where they maintain a stable balance between inward gravitational pressure and outward radiation pressure. The main sequence runs diagonally from high temperature, high luminosity stars (top left) to lower temperature, lower luminosity stars (bottom right).
What type of star is Alcor?
Alcor is a hot, white A5V main sequence star having a luminosity about 13 times that of the sun. The spectral type implies that Alcor has an effective temperature of 8500 K, a diameter 1.7 times that of the sun, and a mass of about 2.2 solar masses. Alcor is a variable star of Delta Scuti type; see Caph.
What type of star has a high temperature and high luminosity in the HR diagram?

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 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.
