What type of star has a high temperature and high luminosity in the HR diagram?
White dwarfs.
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.
Why is there no neurton stars in the hr diagram?
Of course they are on the HR diagram. They are simply not on the main sequence.
Which region contains the most stars in the HR Diagram?
Several regions of the HR diagram have been given names, although stars can occupy any portion. The brightest stars are called supergiants. Star clusters are rich in stars just off the main sequence called red giants. Main sequence stars are called dwarfs.
What diagram classifies stars on a temperature- luminosity graph?
Hertzsprung-Russell (HR) diagram classifies stars based on their luminosity (brightness) and temperature. This diagram allows astronomers to categorize stars into main sequence, giants, supergiants, white dwarfs, and other classes based on their positions in the diagram. It provides insights into the life cycle and evolutionary stage of stars.

Where are stars on the hr diagram?
The HR diagram contains only stars - so everywhere.

Do all stars have a place on the HR Diagram?
Yes, all stars have a place on the Hertzsprung-Russell (HR) Diagram, which plots stars based on their luminosity and temperature. The diagram features distinct regions, including the main sequence, red giants, and white dwarfs, where different types of stars are categorized according to their evolutionary stages. While the exact position of a star on the diagram can change over time as it evolves, every star can be represented at some point in its life cycle.
What are the 3 main groups of stars on an hr diagram?
The three main groups of stars on the Hertzsprung-Russell (HR) diagram are main sequence stars, red giants, and white dwarfs. Main sequence stars, which comprise the majority of stars, fuse hydrogen into helium in their cores and are found along a diagonal band from the upper left to the lower right. Red giants, located in the upper right, are evolved stars that have expanded and cooled after exhausting their hydrogen. White dwarfs, found in the lower left, are remnants of stars that have shed their outer layers and are no longer undergoing fusion.
Are black dwarfs a solid liquid or a gas?
None of the above. White dwarfs and the black dwarfs they will become consist of a unique state of matter called electron degenerate matter.
What is the difference between white dwarfs and black dwarfs?
their colour is one thing but a black dwarf originates from a white dwarf
What two characteristics of stars are shown in an HR diagram?
An HR (Hertzsprung-Russell) diagram illustrates two primary characteristics of stars: their luminosity (or absolute brightness) and their temperature (or spectral class). The diagram typically plots stellar temperature on the horizontal axis, increasing from right to left, while luminosity is shown on the vertical axis, increasing upward. This allows for the classification of stars into different groups, such as main sequence stars, giants, and white dwarfs, based on their evolutionary stages.
