hydrogen burning in the sun?

Question

assuming that the current rate of hydrogen burning in the sun remains constant, what fraction of the sun's mass will be converted into helium over the next 5billion years?

Answer 1

honestly, i cant remember exactly how it goes. but in 5 billion years our sun will either start to cool, or begin fusing helium.

if it starts to cool then all the helium would be gone and in its place would be carbon.

and again if we go by the second choice, in 5 billion years the sun will have used all of its hydrogen so it will have all helium. so in 5 billion years the sun will either be all helium or all carbon.

and our sun is NOT going to go supernova. it will simply expand, then shrink and cool forming a white dwarf, when its completely cooeld it will be a black dwarf.

Answer 2

Hydrogen isn't burnt in the sun. It is fused with another hydrogen atom to make 2/1H (or Deuterium), which is then fused with another 2/1 or a 3/1(tritium) to crewate helium. This fusion process gives off huge amounts of energy - hence the light and heat of the sun.
It's hard to say how much will be made into helium by this process as the sun is so dense that it takes the light made at it's core around 1,000,000 years just to escape to the surface! Although, considering the sun has around 40 billion years left till it goes supernova, I'd say around 1/20th

Alien because of the fact the belief could be to those of your constrained wit, NASA isn't the custodian of all astronomical awareness. to cite from the hyperlink, "In 1920, Sir Arthur Eddington proposed that the pressures and temperatures on the middle of the solar ought to offer a nuclear fusion reaction that merged hydrogen (protons) into helium nuclei, ensuing in a production of means from the internet exchange in mass.The preponderance of hydrogen in the solar replaced into shown in 1925 via Cecilia Payne. The theoretical thought of fusion replaced into stepped forward in the Thirties via the astrophysicists Subrahmanyan Chandrasekhar and Hans Bethe. Hans Bethe calculated the information of the two important means-producing nuclear reactions that means the solar." Bobby and Roger ok have the two spoken wisely.

Answer 4

I could be mistaken, but I think that our star has about 5 billion years left tell it goes super nova. From what I have read, a star like ours only has about a 10 billion year shelf life. Other than that, take the information from the person who answered above.

Answer 5

The rest of it.
