Which is denser a dwarf star or a giant star?
A dwarf star is denser than a giant star. Dwarf stars have a higher density due to their smaller size and higher mass compared to giant stars. Giant stars have larger volumes and lower densities as they have expanded and become less dense towards the end of their life cycle.
A main sequence star of less than 8 solar masses ends its life as a?
A main sequence star of less than 8 solar masses ends its life as a white dwarf. The star goes through the red giant phase before expelling its outer layers to form a planetary nebula, leaving behind a hot, dense core that eventually cools down to become a white dwarf.
Is white drawf bigger than a nertron star?
Simply, neutron star is a big nuclear - of 10km radius and solar mass (mass density about  1017- 1018 kg/m3). The material in a white dwarf is supported by electron degeneracy pressure. The physics of degeneracy yields a maximum mass for a non-rotating white dwarf, the Chandrasekhar limit-approximately 1.4 solar masses-beyond which it cannot be supported by electron degeneracy pressure. The density of white dwarf is - 109 kg/m3. So its radius is much bigger 10km, but the mass can be less, as well as bigger of solar mass.
What happens to a star when the outward force of fusion is less than the inward force?
the star collapses in on itself, and usually when the fusion stops it is in the last stages of its life as a giant or supergiant and forms a white dwarf made of the carbon left over from the second stage of helium to carbon fusion from the core of the star that takes place after the hydrogen to helium fusion. after the white dwarf is formed it will eventually cool off into a black dwarf which is basically a carbon corpse of a star
What type of star is botein?
Botein is a main sequence star located in the constellation Aries. It is classified as a yellow-white dwarf star, similar to our Sun but slightly cooler and less massive.
Is a white dwarf star brighter then a red giant?
No, it is much less bright.
Which is denser a dwarf star or a giant star?
A dwarf star is denser than a giant star. Dwarf stars have a higher density due to their smaller size and higher mass compared to giant stars. Giant stars have larger volumes and lower densities as they have expanded and become less dense towards the end of their life cycle.
Is the density of a pulsar greater than the density of a white dwarf?
Yes, the density of a pulsar is greater than the density of a white dwarf. Pulsars are neutron stars formed from the collapsed core of a massive star, made mostly of neutrons. White dwarfs are less dense than neutron stars, as they are formed from the remnants of low to medium mass stars and are composed mainly of electron-degenerate matter.
How long is the Sun's life expectancy?
It should "live" for about 5 billion years as it is, more or less. Then it will become a red giant star. Then it becomes a white dwarf. Finally it will "die" as a black dwarf.
Is the density of a white dwarf greater or less than material on earth?
The density of a white dwarf is much greater than that of material on Earth. White dwarfs are incredibly dense objects that result from the collapse of a star's core, leading to a mass comparable to the Sun but compressed into a volume roughly the size of the Earth.
How does a black dwarf star form?
A white dwarf is the last stage of a low mass stars life. After a red giant is done fusing helium to carbon and oxygen, the star will collapse to a white swarf. White dwarves are usually between 15,000-6,000 kelvins.A white dwarf is formed when a small or medium-sized star runs out of fuel in its core. The star becomes a red giant and later blow off the shell into the interstellar space. The remaining core becomes a white dwarf.
A main sequence star of less than 8 solar masses ends its life as a?
A main sequence star of less than 8 solar masses ends its life as a white dwarf. The star goes through the red giant phase before expelling its outer layers to form a planetary nebula, leaving behind a hot, dense core that eventually cools down to become a white dwarf.
Where does most of a red giant go when the star becomes a white dwarf?
The white dwarf still has a lot of mass ( about 80% of the original star), but it only has a small size( less than two Earths). A huge volume of material forms a nebula which gradually disperses. This type of nebula is (confusingly) called a "planetary nebula".

Why would white dwarf stars have less amount hydrogen?
A white dwarf is the remnant of a star that has fused all the hydrogen and helium in its core, leaving mostly carbon and oxygen nuclei.
How is proxima centauri similar and different from the sun?
Proxima Centauri is a "red dwarf" star. Its composition is similar to the Sun, but with less mass and it's much smaller than the Sun. It has lower core and surface temperatures. The Sun will eventually start to use helium as well as hydrogen as its fuel It will become a red giant then a white dwarf. Red dwarfs don't have a high enough core temperature to use helium as as "fuel". Proxima Centauri will not become a red giant. It will go straight to the white dwarf stage, once it has used up its hydrogen "fuel".
