An isolated white dwarf uses nuclear fusion to generate energy. Nuclear fusion is the process that occurs when two heavy elements, such as uranium and plutonium, combine to create a new element, such as fusion energy. This process is very dangerous and can only be done in very powerful and expensive reactors.
What is a white dwarf does it produce light in the same way as a star like the Sun?
A white dwarf is a star that has reduced to a very small size. It produces light in the same way as a star like the Sun.
In what manner does an isolated white dwarf generate energy quizlet?
An isolated white dwarf generates energy by converting sunlight into heat.
In what manner does an isolated white dwarf generate energy group of answer choices?
An isolated white dwarf generates energy by emitting light and heat.
What is a white dwarf star primarily composed of?
A white dwarf star is primarily composed of hydrogen gas and dust.
Do white dwarfs emit light?
No, white dwarfs do not emit light.
What happens in a white dwarf supernova?
A white dwarf supernova is the most extreme type of star explosion. It is when a star that is about to die goes supernova. The star’s heat and pressure cause the core to break apart and the outer layers to explode. The star’s outer layer, the gas and dust, is so hot that it can cause a fire. The heat from the explosion causes the star to glow like a star in the night.
What causes a white dwarf star to explode as a supernovae quizlet?
A white dwarf star is a very small, dense star that has exhausted its supply of hydrogen gas and helium. When the star’s temperature reaches about 10,000 degrees Celsius (18,000 degrees Fahrenheit), the hydrogen gas and helium start to fuse, creating a supernova.
What is the ultimate fate of an isolated white dwarf?
If a white dwarf is isolated, it will slowly die from the lack of oxygen and heat.
What type of nuclear fusion is occurring in white dwarfs?
The type of nuclear fusion that is occurring in white dwarfs is called a “gaseous-solid nuclear fusion”.
Will Sun become a white dwarf?
No, Sun will not become a white dwarf.
Where does the energy of a supernova come from?
The energy of a supernova comes from the release of energy in the star’s core.
How does a white dwarf compare to a main sequence star of the same mass?
A white dwarf is a star that has reached the point where it is no longer able to produce energy through nuclear fusion. White dwarfs are much smaller than main sequence stars, and their temperatures are much lower, meaning they have very little light and are much less dense.
How does the white dwarf get the energy to explode?
The white dwarf gets the energy to explode by using the heat of the sun to fusion of the hydrogen and helium in its core.
What kind of pressure prevents a white dwarf from collapsing quizlet?
There is no pressure that prevents a white dwarf from collapsing quizlet.
What kind of pressure supports a white dwarf quizlet?
A white dwarf quizlet is a type of pressure support that helps support a star’s atmosphere.
How does a white dwarf become a black dwarf?
A white dwarf is a star that has reached the point where it has less mass than the sun. Once it reaches this point, it will start to lose heat and will eventually become a black dwarf.
Which of the following is required for helium fusion as compared to hydrogen fusion quizlet?
Which of the following is required for helium fusion as compared to hydrogen fusion quizlet? helium fusion is required for both hydrogen fusion and helium fusionhydrogen fusion is required for helium fusion
How does the accretion disk provide a white dwarf with a new source of energy that we can detect from Earth?
The accretion disk provides the white dwarf with a new source of energy that we can detect from Earth.
What causes a white dwarf supernova?
A white dwarf supernova is caused when a star that is about to go through a rapid and violent phase of its life, called a supernova, explodes in its core. The heat from the explosion causes the star to go through a rapid and violent phase of its life, called a thermonuclear phase. This causes the star to go through a phase of its life where it is so hot that it can no longer hold onto its hydrogen gas and helium gas. The star then collapses, and the pressure and heat from the collapse cause the star to explode.
How does a white dwarf generate its energy?
A white dwarf’s energy comes from the fusion of hydrogen and helium.
What kind of pressure prevents a white dwarf from collapsing?
The pressure of the atmosphere and the weight of the star’s mass prevents a white dwarf from collapsing.
Why does helium fusion require higher core temperatures than hydrogen fusion?
The higher core temperatures required for helium fusion are due to the greater number of protons in the helium nucleus. When these protons are combined with the heat of the fusion reaction, they create a greater amount of energy. This energy is then used to create helium atoms.
What is a nova describe the process that creates a nova and what a nova looks like?
A nova is a star that is born from the merger of two or more stars. It is a very bright object and can be seen from Earth. A nova typically lasts about 10,000 years and is the result of a supernova.
Does fusion take place in white dwarf?
Yes, fusion does take place in white dwarfs. Fusion is the process of combining the mass and energy of two or more stars into one. This happens when the temperature in a white dwarf reaches about 10,000 degrees Fahrenheit.
Which of the following statements is true regarding white dwarf stars?
All white dwarf stars are small and die quickly.A white dwarf star is a small,failed star.
What are characteristics of white dwarfs?
White dwarfs are small, faint, and very faint. They are also very old, having been around for centuries.
What kind of pressure supports a white dwarf?
A white dwarf is a type of star that has reached the end of its life. When it reaches this point, it will have reached the point where it will have lost all of its mass and will be very small. This pressure will be so great that it will have no chance of continuing to exist.
What are white dwarfs quizlet?
What are white dwarfs?White dwarfs are small, dense stars that have exhausted the fuel in their cores and have stopped spinning. They are about the size of Earth and have about the same mass.
What mechanism produces a nova?
A nova is a star that is born from a small galaxy.
Can a white dwarf turn into a neutron star?
There is no definitive answer to this question as it is still a matter of scientific conjecture. Some scientists believe that a white dwarf could become a neutron star, but others believe that it is more likely that this unlikely event will never happen.
