The Main Sequence:
The Sun, like most stars in the Universe, is on the main sequence stage of its life, during which nuclear fusion reactions in its core fuse hydrogen into helium.

What is the main sequence of the Sun's Life?

Like most stars in our universe, the Sun is on the main sequence stage of its life. This means nuclear fusion reactions in its core fused hydrogen into helium. However, this process cannot last forever since there is a finite amount of hydrogen in the …

How do you find the life cycle of the Sun?

May 07, 2015 · The Fate of Sun-Sized Stars: Black Dwarfs Once a medium size star (such as our Sun) has reached the red giant phase, its outer layers continue to expand, the core contracts inward, and helium atoms in the core fuse together to form carbon. This fusion releases energy and the star gets a temporary reprieve.

What is the first stage of the life cycle of stars?

Apr 18, 2013 · - Answers The Sun started out in a Stellar Nebulae, then became a Protostar. Afterwards, it gained enough hydrogen and pressure to start hydrogen fusion. Once that occurs, the sun entered its Main...

What stages of life will our Sun go through?

The Sun is currently a main sequence star and will remain so for another 4-5 billion years. It will then expand and cool to become a red giant, after which it will shrink and heat up again to become a white dwarf. The white dwarf star will run out of nuclear fuel and slowly cool down over many billions of years.

What stages will the sun go through towards the end of its life?

Once all the helium disappears, the forces of gravity will take over, and the sun will shrink into a white dwarf. All the outer material will dissipate, leaving behind a planetary nebula. "When a star dies, it ejects a mass of gas and dust — known as its envelope — into space.Jan 7, 2022

What are the 6 stages of the Sun's life cycle?

Formation of Stars Like the SunSTAGE 1: AN INTERSTELLAR CLOUD.STAGE 2: A COLLAPSING CLOUD FRAGMENT.STAGE 3: FRAGMENTATION CEASES.STAGE 4: A PROTOSTAR.STAGE 5: PROTOSTELLAR EVOLUTION.STAGE 6: A NEWBORN STAR.STAGE 7: THE MAIN SEQUENCE AT LAST.Dec 12, 2021

Is the Sun halfway through its life?

So our Sun is about halfway through its life. But don't worry. It still has about 5,000,000,000—five billion—years to go. When those five billion years are up, the Sun will become a red giant.

What is the main sequence stage of the Sun?

The Main Sequence Stage. Like most stars in our universe, the Sun is on the main sequence stage of its life. This means nuclear fusion reactions in its core fused hydrogen into helium. However, this process cannot last forever since there is a finite amount of hydrogen in the core of the Sun. Currently it has more than 72% hydrogen. ...

How long did the Sun's life cycle last?

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. The Sun and all our planets in the solar system began as a giant cloud of molecular gas and dust.

What happens to the red giant after the Sun swallows Earth?

About one billion years after the Sun tries to swallow Earth, the red giant will undergo a process called Helium flash where huge amounts of Helium is fused to Carbon in a matter of minutes. Once the Helium in the core starts fusion, the star will then shrink but gain luminosity.

What happens to the Sun when it fuses with the dead core?

Then, our star will enter the red giant phase and swell up much faster. It is calculated that the expanding Sun will grow large enough to encompass the orbits of Mercury, Venus, and maybe even Earth.

How long did the Sun last?

The Sun spent about 100,000 years as a collapsing protostar before temperatures and pressures in the interior ignited fusion at its core. And just a few million years later, it settled down into its current form. The life cycle of the Sun has now begun.

How much brighter will the Sun be in a billion years?

One billion years from now, the Sun will be 10% brighter than it currently is. This will trigger a moist greenhouse effect here on Earth that is similar to the hellish Venus environments that we see today. Under these conditions, life as we know it will be unable to survive anywhere on the surface of Earth.

How long does it take for the Sun to throw away its mass?

These powerful bursts of radiation will cause the Sun to fling wave after wave of material out into space. After about 500,000 years of these stellar tantrums, the Sun will have tossed away half of its mass. That discarded material will briefly form a beautiful planetary nebula.

What happens when a star's core is heated?

The repulsive force between the nuclei overcomes the force of gravity, and the core recoils out from the heart of the star in an explosive shock wave. As the shock encounters material in the star's outer layers, the material is heated, fusing to form new elements and radioactive isotopes.

What happens to the stars when they reach the red giant phase?

Once a medium size star (such as our Sun) has reached the red giant phase, its outer layers continue to expand, the core contracts inward, and helium atoms in the core fuse together to form carbon. This fusion releases energy and the star gets a temporary reprieve.

Why are neutron stars so interesting?

Neutron stars are fascinating because they are the densest objects known. Due to its small size and high density, a neutron star possesses a surface gravitational field about 300,000 times that of Earth. Neutron stars also have very intense magnetic fields - about 1,000,000,000,000 times stronger than Earth's.

What kind of energy does the electrons release?

At this radius, the electrons must stop, and they release some of their kinetic energy in the form of X-rays and gamma-rays. External viewers see these pulses of radiation whenever the magnetic pole is visible. The pulses come at the same rate as the rotation of the neutron star, and thus, appear periodic.

Why is the White Dwarf stable?

It has become a white dwarf. White dwarfs are stable because the inward pull of gravity is balanced by the electrons in the core of the star repulsing each other. With no fuel left to burn, the hot star radiates its remaining heat into the coldness of space for many billions of years.

What happens when a ball of gas and dust moves off into space?

When the released energy reaches the outer layers of the ball of gas and dust, it moves off into space in the form of electromagnetic radiation. The ball, now a star, begins to shine. New stars come in a variety of sizes and colors.

What happens to the core of a supergiant?

Unlike in smaller stars, where the core becomes essentially all carbon and stable, the intense pressure inside the supergiant causes the electrons to be forced inside of (or combined with) the protons, forming neutrons. In fact, the whole core of the star becomes nothing but a dense ball of neutrons.

Hints

The sun is a middle-aged star. The sun is made of about 74% hydrogen and 24% helium. (Cain, 2008)
