What will the Sun end up as when its nuclear energy source dies out forever?
The Sun will eventually end up as a white dwarf, a dense, Earth-sized remnant of a star. This will happen after it exhausts its nuclear fuel and sheds its outer layers into space, forming a planetary nebula.
Does the sun create energy with fission or fusion?
The Sun is a GV2 class star, commonly called a "yellow dwarf". The "V" indicates that the Sun is a main sequence star (plotted on stellar color rather than brightness), and like all dwarf stars, its energy is derived from nuclear fusion of hydrogen into helium. The Sun fuses an estimated 620 million metric tons of hydrogen each second in it's core.
Is a white dwarf star is one that does not have fuel to make is own energy?
That's called a "black dwarf". Such objects are hypothetical; they are not expected to exist yet, since it takes a white dwarf longer, to cool down to a black dwarf, than the current age of the Universe.
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.
Why is solar energy considered a renewable energy source?
Because it can be collected without running out of... sunlight. Many resources like forests, coal, oil, etc. will (in the long run) be depleted. However, we will continue to receive light from the sun for a long time, which is why it is considered renewable. > Not sure it is renewable, its like a big fire, once its fuel is depleted it collapses into a white dwarf. All non renewable sources can be traced back to the suns energy.
How are stars made with fusion reaction big bang giant nebula white dwarf and protostar?
white dwarf is an age that a star reaches but the big bang is an explosion of nuclear energy that makes a star
What will the Sun end up as when its nuclear energy source dies out forever?
The Sun will eventually end up as a white dwarf, a dense, Earth-sized remnant of a star. This will happen after it exhausts its nuclear fuel and sheds its outer layers into space, forming a planetary nebula.
What gas is being used as a fuel source for the white dwarf?
The gas being used as a fuel source for white dwarfs is primarily hydrogen. During nuclear fusion reactions in the core of a white dwarf, hydrogen atoms are fused together to form helium, releasing energy in the process.
When a white dwarf star no longer emits energy what does it become?
When a white dwarf star no longer emits energy, it becomes a black dwarf. Black dwarfs are theoretical end points of stellar evolution where all nuclear reactions have ceased, and the star has cooled down to the background temperature of the universe.
Why is a white dwarf considered a dead star?
A white dwarf is not considered a "dead star." It is considered a dying star, but not dead yet. A white dwarf is at its smallest state and could become a supernova when its center runs out of fuel to burn.
What is plutonium used for and where did it get its name from?
The name plutonium is derived from the name of the dwarf planet Pluto; dwarf planet Pluto is after planet Neptune in the Solar system and plutonium is after neptunium in the periodic table of Mendeleev. Applications of plutonium include: • explosive in nuclear weapons • nuclear fuel in nuclear power reactors (as plutonium dioxide, carbide or MOX) • the isotope 238Pu is used as energy source in spacecrafts or other applications (radioisotope thermoelectric generators); the chemical form is plutonium dioxide. • neutron generator, as Pu-Be source
Explain the role of nuclear fusion in the life cycle of a star?
Nuclear fusion is the process by which stars generate energy by fusing lighter elements into heavier ones. In the life cycle of a star, nuclear fusion occurs in the core and provides the energy necessary to counteract gravitational forces and maintain the star's equilibrium. As a star exhausts its nuclear fuel, it may undergo different stages of fusion, eventually leading to its death.
What produces energy in the Sun alpha reactions proton splitting nuclear reactions or yellow dwarfs?
The energy output of the Sun derives from nuclear fusion reactions. A yellow dwarf is not a process, it's a type of star, of which the Sun is one.
How does a white dwarf produce light and heat?
There is no source of energy heating a white dwarf. The heat is left over from when it was a full-fledged star, like a stone pulled from the coals of a fire. The white dwarf glows simply because it is very hot.
Does a white dwarf star use hydrogen for energy?
No, white dwarf stars do not undergo nuclear fusion like main sequence stars, including our Sun. White dwarf stars are the remnants of low to medium mass stars, and they use stored thermal energy to shine and gradually cool over time.
Is white dwarf a dead star?
Yes - in the sense that it no longer produces energy. In other words, the star has run out of fuel for nuclear fusion.
What is the initial source of energy for the collapsing star?
Gravitational potential energy drives the collapse throughout the life of a star, from birth to death.it drives the initial collapse of the nebula into the protostar.it drives the collapse of the protostar into a star, igniting nuclear fusion.it holds the star together against the outward pressure of nuclear fusion.it drives the collapse of the star after nuclear fusion burns out, forming either a white dwarf, a neutron star, or a black hole. depending on its mass before nuclear fusion burned out.
