By far the most common type of star is the red dwarf star. These stars are between 7.5% and 50% of the mass of the Sun. About half the stars in the Milky Way are red dwarf stars. For example, Proxima Centauri, the closest star to the Sun, has a mass of 12.3% of the Sun's mass, which comes to 2.4*10^29 kg.
The theoretical minimum of a star, burning hydrogen through nuclear fusion, is around 0.08 solar masses. The most massive known star is a blue hypergiant called R136a1. It's around 265 times more massive than our sun.
If a star is above the Chandrasekhar limit of about 1.4 solar masses, then the star cannot maintain its size due to the repulsive forces of the atomic nuclei; the star will collapse into a neutron star. If it is spinning (and most of them are) we might call it a "pulsar".
Anything below about 75 or 80 Jupiter masses would be called a brown dwarf, which doesn't get hot enough for nuclear fusion, except that it may fuse deuterium. And anything below about 13 Jupiter masses can't fuse deuterium either, and would be considered a planet.
A dying star sheds most of its mass during the red giant stage. Only a fraction of the mass is left behind in the white dwarf.
A white dwarf, because of it's structure can only form from a star that has a mass of between 0.6 and 1.4 Suns.

This is known as the Chandrasekhar limit, it's around 1.4 solar masses or 2.8 × 10 to the power of 30 kg.
Above that mass, the white dwarf's "degeneracy pressure" isn't strong enough against the strong gravity, and it will collapse into a neutron star.

Mass of sun is 2*1030 Kg

Stellar masses can be determined by observing binary star-systems. The calculations of the orbits of the binary stars allow the masses of their component stars to be directly determined, which in turn allows other stellar parameters, such as radius and density, to be indirectly estimated.
A star that was 150 solar masses would spend the main part of its life as a main sequence star before collapsing into a white dwarf. A stars mass determines the life expectancy as well as its probable cause of death.
Stars do not have weight they have mass. Our Sun is said to be one solar mass or 1.98892×1030 kg. There are stars smaller than our Sun (read dwarfs) which can be down to 0.075 solar masses and stars much much bigger than the Sun (Hypergiants) which can reach 80-150 solar masses.
All stars are in a balance between gravity crushing them in, and the pressure caused by nuclear fusion at the star's core. And the bigger the star, the greater the amount of energy generated. At some point, the pressure of the stellar fusion is SO powerful that the outer layers of the star are blasted off into space. That point, we believe, is at about 150 solar masses.
As the HR diagram shows, the hottest stars on the main sequence range from 30,000K as blue-white stars to about 3,000K as redish stars.
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.
Stars don't have dunes, as they are masses of burning gas.
Stars with larger masses have stronger gravity; this results in more pressure; which in turn makes the star hotter. As a result of the higher temperature, they will shine brighter, and burn their fuel much faster.
Stellar masses can be determined by observing binary star-systems. The calculations of the orbits of the binary stars allow the masses of their component stars to be directly determined, which in turn allows other stellar parameters, such as radius and density, to be indirectly estimated.
What the core of the star will become is dependent of the mass of the supergiant star. Stars between about 3 and 10 solar masses will generally become neutron stars. Stars above 10 solar masses generally become black holes.
All stars are born with Hydrogen making up 100% of their mass. As they spend their lives, the composition changes from star to star, depending on their masses.
It is a main sequence star of class M. It can range in size form 0.08 to 0.45 solar masses, and a radius of less than 0.7 times that of the sun. A majority (76%) of main sequence stars belong to this category.
Whether a star will become a neutron star is determined by its mass. Generally, stars that are more than 8 solar masses (have a mass that is more than 8 times that of our Sun), but are less than 15 solar masses will become neutron stars when they die.
Our galaxy, the milky way, has stars much bigger than our sun. Our sun is considered one solar mass in it's size. The Milky Way has star that range from 1/2 a solar mass to 50 or 100 solar masses.
No, stars come in many different sizes, masses and densities. Further, a star will change its size over its lifespan.
The official unit for mass in science (and elsewhere), of course, is the kilogram. In astronomy, for ease of comparison, the masses of stars, and even galaxies, are often expressed in "solar masses", meaning multiples of the mass of our Sun.
It depends on the mass of the star and how much of the star actually goes into the remnant.Stars between 10 and 25 times the mass of the sun form neutron stars. Stars over 40 solar masses form black holes. Stars between 25 and 40 solar masses can form either depending on how much of the star is blown away during the supernova and how much falls back into the collapsing core.
