What happens when a star runs out of hydrogen fuel?
When a main sequence star begins to run out of hydrogen fuel, the star becomes a red giant or a red super giant. THE DEATH OF A LOW OR MEDIUM MASS STAR
How does a star become a planet?
The center of the disc becomes a star while the rest can become a system of planets. come from giant or massive stars. They grow to as much as three times the mass of our sun as they lose the nuclear fuel at their core. The outer layer of this red star expands as the core contracts.
What happens when a high mass star dies?
After a low or medium mass or star has become a red giant the outer parts grow bigger and drift into space, forming a cloud of gas called a planetary nebula The blue-white hot core of the star that is left behind cools and becomes a white dwarf. The white dwarf eventually runs out of fuel and dies as a black dwarf. THE DEATH OF A HIGH MASS STAR
What happens first when a star runs out of fuel?
What happens first when a star begins to run out of fuel? The star's core shrinks.
What happens to a red supergiant star once it runs out of hydrogen gas in its core?
Once the high mass star starts to run out of hydrogen in the core, and starts burning hydrogen in the shell, it expands into a Red Giant stage just like we saw for low mass stars.
What happens to pressure when a star runs out of fuel?
Once a star has exhausted its supply of hydrogen in its core, leaving nothing but helium, the outward force created by fusion starts to decrease and the star can no longer maintain equilibrium. The force of gravity becomes greater than the force from internal pressure and the star begins to collapse.
What happens to a star when it runs out of its hydrogen fuel?
Eventually the core of the star runs out of hydrogen. When that happens, the star can no longer hold up against gravity. Its inner layers start to collapse, which squishes the core, increasing the pressure and temperature in the core of the star.
What is a red supergiant star explodes called?
A supernova is a powerful and luminous explosion of a star. It has the plural form supernovae /-viː/ or supernovas, and is abbreviated SN or SNe. This transient astronomical event occurs during the last evolutionary stages of a massive star or when a white dwarf is triggered into runaway nuclear fusion.
What causes a star to turn into a red giant?
A red giant forms after a star has run out of hydrogen fuel for nuclear fusion, and has begun the process of dying. A star maintains its stability through a fine balance between its own gravity, which holds it together, and the outwards pressure from ongoing thermonuclear fusion processes taking place at its core.
Which object forms when a supergiant explodes?
After a super giant explodes some material is left behind. This material may form a neutron star.
What happens when star has consumed all its fuel and explodes?
Once a star like the Sun has exhausted its nuclear fuel, its core collapses into a dense white dwarf and the outer layers are expelled as a planetary nebula.
What happens to the gas that escapes into space at the end of a star's life cycle?
The outer layers of gas will expand and the stars will become red giant stars. Eventually when the core of a red giant star cools, the remaining gas will float into space, forming a planetary nebula. Each planetary nebula has a white dwarf star at its core.
What will happen when the sun becomes a red giant?
As our star ends its life, it will swell far beyond its current size, and as it does so, it will transition into a Red Giant. During this transformation, the sun will melt our glaciers and (eventually) boil our oceans. This expanding Sun will engulf the Earth, and any life that remains along with it.
When our sun starts to run out of fuel it will swell up and become a?
The life cycle of the Sun began roughly 4.6 billion years ago and will continue for almost another 8 billion years when it will have depleted its supply of nuclear fuel and collapse into a white dwarf.
What happens to the core of a high mass star after it runs out of hydrogen it shrinks and heats up it shrinks and downs helium fusion begins right away?
When ever the stars core hydrogen is depleted , nuclear fusion will cease. Without fusion to supply thermal energy the star Will become out of balance for the first time. This causes the core to shrink. Outer layers will expand outward, even though its core will be shrinking under the crush of gravity.
When a star runs out of hydrogen to fuse into helium in the core what type of star does it become?
The core becomes a White Dwarf the star eventually cools and dims. When it stops shining, the now dead star is called a Black Dwarf. Stage 1 - Massive stars evolve in a simlar way to a small stars until it reaces its main sequence stage (see small stars, stages 1-4).
When a star has used up all the hydrogen in its core?
(1) When a star exhausts the hydrogen in its core, it becomes a giant or supergiant. Once a star has used up all the hydrogen in its core, fusion of hydrogen into helium stops. The core starts to contract again (just as it contracted as a protostar, before hydrogen fusion began).
What will happen to a star if its core can no longer produce the needed energy?
The sudden stoppage of energy generation causes the core to collapse and the outer layers of the star to fall onto the core. The infalling layers collapse so fast that they `bounce' off the iron core at close to the speed of light. The rebound causes the star to explode as a supernova.
What does a low mass star become when it runs out of hydrogen to fuse?
Over its lifetime, a low mass star consumes its core hydrogen and converts it into helium. The core shrinks and heats up gradually and the star gradually becomes more luminous. Eventually nuclear fusion exhausts all the hydrogen in the star's core.
Expert-verified answer
The star becomes a white dwarf when it begins to run out of fuel. Option C is correct.
Answer
A) The stars core shrinks The star will contract under the weight of gravity. When it contracts it will heat up and expand to a red giant. When the star runs out completly of helium it would emit gasses and form a star nebula. It would then become a white dwarf then into a black dwarf.
What is a Giant Star?from universeguide.com
Giant Stars including Supergiants and Hypergiants are stars that are larger in size compared to other stars of the same temperature. Giants are the smaller of the group followed by Supergiant and then Hyper. Our Sun is actually classed as a Dwarf Star because it is much smaller than some of the giants out there. The Sun is more massive than 95% of stars in the cosmos and 75% of stars in the cosmos are red dwarf stars. Forbes

What is the biggest star in the universe?from universeguide.com
There is a discussion on-going as to what is the biggest star in the galaxy, we can only talk about the stars that have been observed. The current biggest is UY Scuti , a star in the Constellations of Scutum. If you research the internet, you will find that some sites will say that the biggest is VY Canis Majoris or NML Cygni in the constellation of Cygnus the Swan. These stars are measured in terms of solar radii, a radii of 1 is the same size as our Sun such as Rigil Kentaurus also known as Alpha Centauri. Anything less that 1 will indicate it is a smaller star. UY Scuti is estimated to be about 1,708 times the radius of our Sun. NML Cygni, another contender for the biggest star has a radius of between 1,642 and 2,775 times the Sun.
Why do stars have a supergiant spectral feature?from en.wikipedia.org
The most massive stars develop giant or supergiant spectral features while still burning hydrogen in their cores, due to mixing of heavy elements to the surface and high luminosity which produces a powerful stellar wind and causes the star's atmosphere to expand .

What is a super AGB star?from en.wikipedia.org
Stars in the 8-12 M☉ range have somewhat intermediate properties and have been called super-AGB stars. They largely follow the tracks of lighter stars through RGB, HB, and AGB phases, but are massive enough to initiate core carbon burning and even some neon burning. They form oxygen–magnesium–neon cores, which may collapse in an electron-capture supernova, or they may leave behind an oxygen–neon white dwarf.

How does gravity affect the protostar?
Heat and pressure build in the core of the protostar until nuclear fusion takes place. The force of gravity pulls a nebula together forming clumps called protostars. Hydrogen atoms are fused together generating an enormous amount of energy igniting the star causing it to shine.
How many hours of daylight does Earth have without tilt?
Without tilt, every day and every place on Earth (except the poles) would have exactly 12 hours of daylight and 12 hours of night. It is the tilt that causes seasonal differences in the length of night and daylight— longer nights in winter and longer days in summer.
How big can a nebula grow?
They grow to as much as three times the mass of our sun as they lose the nuclear fuel at their core. The outer layer of this red star expands as the core contracts. 3. Nebula can form either an star that is about the size of our Sun or a star which can be over three times as big as our Sun!
Why is the Sun high in the sky in summer and low in the sky in winter?
It is the tilt that causes the Sun to be high in the sky in summer and low in the sky in winter. It is the combination of longer daylight hours and more direct sunlight that causes the heat of summer, and the combination of shorter daylight hours and less direct sunlight that causes the cold of winter.
What happens at the end of the life of a giant star?
At the end of the life of a giant star, a is resulted when a red supergiant's core collapses in on itself. The electrical forces at the center of the star overcome the gravitational pull and create a massive explosion that scatters the outer layers of the red supergiant. 5.
