In about 5 billion years at the end of its lifetime the Sun will end up as a white dwarf having about the same mass but reduced to about 15000 km in diameter What will be its density?
If the diameter is 15,000 km = 15,000,000 meters -> radius = 7,500,000 meters Volume -> 4*pi*r3/3 = 1.77×1021 m3 Mass of the Sun = 1.9891×1030 Density=M/V=1.9891×1030 / 1.77×1021 = 1,123,785,310.7 kg/m3
What are the main features depicted in a white dwarf diagram?
A white dwarf diagram typically shows the main features of a star in the final stage of its life cycle, including its small size, high density, and cooling temperature. It may also display the relationship between luminosity and temperature as the star evolves.
What would happen if a white dwarf gained enough mass to reach the 1.4 solar-mass white dwarf limit?
If a white dwarf gained enough mass to reach the 1.4 solar-mass white dwarf limit, it would undergo a catastrophic event known as a Type Ia supernova. This explosion would release a tremendous amount of energy and result in the complete destruction of the white dwarf.
What happens to the size of a white dwarf when its mass is increased?
When the mass of a white dwarf increases, its size decreases. This is because the increased mass causes the white dwarf to contract under its own gravity, making it smaller and denser.
What is the upper limit to the mass of a white dwarf?
The upper limit to the mass of a white dwarf is about 1.4 times the mass of the Sun, known as the Chandrasekhar limit. Beyond this point, the white dwarf may collapse and explode in a supernova event.
Is a pulsar star a white dwarf?
No. A pulsar is a neutron star.
Is a plusar a white dwarf?
No. A pulsar is a neutron star.
How does a white dwarf star or pulsar form?
See related questions.
What happens star's furnace stops?
Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.
Will the sun turn into a pulsar?
No. It does not have enough mass. Only stars 8 times the mass of the sun or greater can become pulsars. The sun will become a white dwarf.
How dense is the white dwarf to your sun?
A white dwarf is much denser than the Sun. White dwarfs have a typical density around 1 million times greater than the density of the Sun, resulting in a mass similar to the Sun's but packed into a much smaller volume.
What planet with a mass 10 times greater than Earth's was discovered to be orbiting in 1992?
Is it a pulsar, a G2 star, a supergiant or a white dwarf? Please answer one of the following.
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.
Is A pulsar is a white dwarf true or false?
False. A pulsar is not a white dwarf; it is a highly magnetized, rotating neutron star that emits beams of electromagnetic radiation. Pulsars are the remnants of supernova explosions, while white dwarfs are the remnants of low to medium-mass stars that have exhausted their nuclear fuel and shed their outer layers.
What is the term for the tiny and very dense white dwarf star that is left behind after a supernova?
I think that's a pulsar.
What is the density of a white dwarf which contains 1.3 Msun using the volume of the Earth?
To calculate the density of the white dwarf, we first need to determine its volume using the volume of the Earth. The volume of the Earth is about 1 trillion cubic kilometers. If we assume the white dwarf is roughly the same size as the Earth, its density would be the mass (1.3 Msun) divided by the volume of the Earth. This calculation would yield a rough estimate of the white dwarf's density.
Is the density of a neutron star about the same density as a white dwarf?
No, the density of a neutron star is much higher than that of a white dwarf. Neutron stars are composed mostly of densely packed neutrons, while white dwarfs are made of electron-degenerate matter. Neutron stars are some of the densest objects in the universe.
