How long does it take for a star with the same mass as the sun to become a star?
It takes 10,000,000 years to make all the hydrogen in a star with the same mass as the sun into helium.
You might also wonder what happens to stars 8 times as large as the Sun's?
Stars with a lot mass could end up as neutron stars or black holes. A white dwarf is a star with a low or medium mass (less than 8 times that of the Sun). Outward pressure is created by the heat generated by the Sun's nuclear fusion of hydrogen and helium.
What happens to a star if it becomes a giant red star? The Sun and all red dwarfs over 0.25 solar mass will grow into what's known as a red giant. This is the final stage in stellar evolution. This stage is when the star begins to fuse different elements and then eventually throws away its layers as a planet nebula.
A similar question was asked: What happens to a star with 8 to 20 times as much mass as the sun?
Stars with masses between 8 and 20 times that of the Sun will have a core too large to support electron pressure. This star ends in a fiery fashion. The star's core continues to crumble, compressing matter into a smaller volume.
What happens to a star if it becomes a giant red quizlet?
A red giant star is one that cools down and expands after it has used most of its hydrogen. A red supergiant star is a star whose center shrinks as it grows.

Can a star of 2.5 solar masses ever become a white dwarf?
The upper mass-limit for a main sequence star that will go on to form a white dwarf rather than a neutron star is not precisely known but is thought to be about 8 solar masses. A 2 solar-mass star will probably end up as a 0.7 solar-mass white dwarf.
Will our Sun become a black hole?
Only stars with very large masses can become black holes. Our Sun, for example, is not massive enough to become a black hole. Four billion years from now when the Sun runs out of the available nuclear fuel in its core, our Sun will die a quiet death. Stars of this type end their history as white dwarf stars.
What is a star's life cycle?
A star's life cycle is determined by its mass. The larger its mass, the shorter its life cycle. A star's mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born. The outer shell of the star, which is still mostly hydrogen, starts to expand.
What happens to a star when it dies?
A star collapses when the fuel is used up and the energy flow from the core of the star stops. Nuclear reactions outside the core cause the dying star to expand outward in the "red giant" phase before it begins its inevitable collapse. If the star is about the same mass as the Sun, it will turn into a white dwarf star.
What is a supernova made of?
As the star runs out of nuclear fuel, some of its mass flows into its core. Eventually, the core is so heavy that it cannot withstand its own gravitational force. The core collapses, which results in the giant explosion of a supernova. The sun is a single star, but it does not have enough mass to become a supernova.
Why are white dwarfs white?
A white dwarf is very dense: its mass is comparable to that of the Sun, while its volume is comparable to that of Earth. A white dwarf's faint luminosity comes from the emission of stored thermal energy; no fusion takes place in a white dwarf.
Is the sun a red giant?
In approximately 5 billion years, the sun will begin the helium-burning process, turning into a red giant star. When it expands, its outer layers will consume Mercury and Venus, and reach Earth.
Is the sun a red dwarf?
The sun is classified as a G-type main-sequence star, or G dwarf star, or more imprecisely, a yellow dwarf. Actually, the sun — like other G-type stars — is white, but appears yellow through Earth's atmosphere. The sun will puff up into a red giant and expand past the orbit of the inner planets, including Earth.
What is the birth of a star called?
Star birth. Like people, stars are born, they grow old and they die. Their birth places are huge, cold clouds of gas and dust, known as 'nebulas'. The most famous of these is the Orion nebula, which is just visible with the unaided eye.
What happens next depends on the mass of the star?
The Fate of Massive Stars
Next, the core starts to shrink, becoming very hot and dense. Then, fusion of helium into carbon begins in the core. When the supply of helium runs out, the core will contract again, but since the core has more mass, it will become hot and dense enough to fuse carbon into neon.What is the life of Sun?
Existing for about 4 and a half billion years, it has burnt up about half of the hydrogen in its core. This leaves the Sun's life expectancy to 5 billion more years, at which time, the Sun's elements will "swell" up, swallow Earth, and eventually die off into a small white dwarf.
What is the closest star to Earth?
Alpha Centauri A
How a star is born in space?
A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. All stars are the result of a balance of forces: the force of gravity compresses atoms in interstellar gas until the fusion reactions begin.
Do stars move?
The stars move along with fantastic speeds, but they are so far away that it takes a long time for their motion to be visible to us. You can understand this by moving your finger in front of your eyes. Even when you move it very slowly, it may appear to move faster than a speeding jet that is many miles away.
Are all stars white?
The color of a star is linked to its surface temperature. The hotter the star, the shorter the wavelength of light it will emit. The hottest ones are blue or blue-white, which are shorter wavelengths of light. Cooler ones are red or red-brown, which are longer wavelengths.
What causes a supernova?
What causes a supernova? One type of supernova is caused by the “last hurrah” of a dying massive star. This happens when a star at least five times the mass of our sun goes out with a fantastic bang! Massive stars burn huge amounts of nuclear fuel at their cores, or centers.
Where are stars born?
Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.
