How do the stars radii compare with their mass?
The radii of stars generally increase with their mass due to the relationship described by the mass-radius relation in stellar astrophysics. More massive stars possess stronger gravitational forces, which result in higher pressures and temperatures in their cores, leading to larger radii as they expand. However, this relationship is not linear; while main-sequence stars follow a trend where radius increases with mass, giants and supergiants can have much larger radii relative to their mass. Overall, more massive stars tend to be larger, but the exact relationship can vary depending on a star's evolutionary stage.
How do a stars radius compare with their mass?
The radius of a star is generally proportional to its mass. More massive stars tend to have larger radii compared to less massive stars. This relationship is governed by the balance between the gravitational force pulling the star inward and the pressure from nuclear fusion reactions pushing outward.
How can solar radii be used to describe the sizes of star including the subgroups of white dwarf giants and supergiants?
A star's radius is the distance from it centre to its visible surface. The bigger the star, the larger the radius. The radius is not the best means of comparing stars, it is perhaps better to compare stars by their mass.
What is a solar radii?
A solar radii is a unit of measurement used to describe the size or distance of an object relative to the Sun. It is often used in astronomy to compare the size of stars or planets to that of the Sun. One solar radii is equal to the radius of the Sun.
What is the typical size of the typical white dwarf in solar radii?
The typical size of a white dwarf is about the size of Earth, which is approximately 0.008 solar radii. White dwarfs are very dense objects that have collapsed from the remnants of low to medium mass stars.

How do the numbers of low-mass stars compare with those of higher-mass stars in new star clusters?
In a newly formed star cluster stars with low masses must greaty out number stars with high masses. High mass stars are rare and low mass stars are extremely common.

How do the lengths of two radii of the same circle compare?
The sum of two radii of a circle is the same as the diameter of the circle.
Does smaller mass stars have a greater luminosity than larger mass stars?
This is not necessarily true. most of the time stars with a larger diameter have more mass but some stars with a smaller diameter are more dense and have a greater mass. Find a main sequence star chart and you can compare the data.
What is the difference between a giant and a supergiant star?
Typically,giant stars have radii between 10 and 100 solar radii and luminosities between 10 and 1,000 times that of the Sun.Whereas Supergiants have a radii between 30 and 1,000 solar radii and luminosities between 30,000 and 100,000 times that of the Sun
Compare and contrast super giants and giant stars?
Super giants are more massive and have larger radii than giant stars. Super giants are in a more advanced stage of stellar evolution compared to giant stars. Both types of stars eventually exhaust their nuclear fuel and go on to evolve into other stages, such as supernovae or white dwarfs.
What are the four stars bigger than sun?
Actully, there are more than just four stars bigger than the sun. 5% of the stars are bigger than the sun. The sun just looks so big because it's closer to Earth. :~)
If your mass on earth is m your mass at a distance of 3 earth radii from the center of the earth will be while your weight will be?
-- If your mass is 'm', then your mass is 'm', regardless of whether you're on the earth,2 earth radii out in space, or on the moon. Mass doesn't change.-- On the surface, your distance from the center of the earth is 1 earth radius. Weight isinversely proportional to the square of the distance from the center of the earth, so at adistance of 3 earth radii from the center, your weight is 1/32 = 1/9th of your weight on thesurface. If your mass is 'm' then your weight on the surface is mg = 9.8m newtons, and at3 earth radii from the center it's 1.089m newtons (rounded).
How Big Are White Dwarf Stars exact number in kilometres?
The universe is a much more complicated place than you seem to believe.The radius of a white dwarf star (I assume you mean a degenerate dwarf, not a main sequence star that happens to be white, which could also be called a "white dwarf") depends on its mass. An interesting property is that higher-mass stars have smallerradii.While we can't provide "an exact number in kilometers" (or any other unit), we can say that the majority of white dwarfs have radii between 0.008 and 0.02 solar radii (5600 to 14000 kilometers).
