the process is called "nuclear fission ". that means the combining of two hydrogen atoms into one , that is helium . it generates huge amount of energy . it has not yet been done sucessfuly by humans , because it is unstable .however we have controlled nuclear fission . that is just the reverse of it
What else can I help you with?
Why does the amount of hydrogen in a star decrease over time?
The amount of hydrogen in a star decreases over time because the star fuses hydrogen into helium in its core through the process of nuclear fusion. This conversion of hydrogen into helium releases energy that powers the star and results in a gradual depletion of its hydrogen fuel source.
What gas is exchanged into helium in a stars nuclear reactions?
In a star's nuclear reactions, hydrogen is converted into helium. This process, known as nuclear fusion, occurs in the core of a star, where high temperatures and pressures cause hydrogen atoms to combine to form helium.
What is the process that generates energy in the core of the main sequence star?
The process is nuclear fusion of hydrogen. All stars at their main sequence converts hydrogen to helium giving large energy by during hydrogen atoms into helium nucliiFusion of hydrogen.
What is the process that generates energy in the core of a main sequence star?
The process is nuclear fusion of hydrogen. All stars at their main sequence converts hydrogen to helium giving large energy by during hydrogen atoms into helium nucliiFusion of hydrogen.
Why is the presence of large amount of helium in the spectrum of a star considered to be a sign of age?
Stars fuse hydrogen into helium, and then fuse the helium into carbon. For a star to have more than about 50% helium, we know that the star has already burned up half of its natural fuel, and that the end is near.
What process does hydrogen changes to helium during a star's life cycle?
Nuclear fusion
Why does the amount of hydrogen in a star decrease?
The amount of hydrogen in a star decreases over time because hydrogen fuses into helium through nuclear reactions in the star's core, releasing energy in the process. As the star continues burning hydrogen, it eventually exhausts its hydrogen fuel supply, leading to changes in its structure and behavior.
What is the first element that is converted in a star's core?
The first element that is converted in a star's core is hydrogen. Through nuclear fusion, hydrogen atoms fuse together to form helium, releasing energy in the process. This fusion process is what powers a star and allows it to shine.
What nuclear process is occurring during the main sequence star?
Hydrogen -> Helium
Why does the amount of hydrogen in a star decrease over time?
The amount of hydrogen in a star decreases over time because the star fuses hydrogen into helium in its core through the process of nuclear fusion. This conversion of hydrogen into helium releases energy that powers the star and results in a gradual depletion of its hydrogen fuel source.
What combines to form helium atoms in a star?
Helium atoms in a star are formed through the process of nuclear fusion. In the core of a star, hydrogen atoms combine through a series of fusion reactions to form helium atoms. This happens when hydrogen atoms collide and fuse together, releasing energy in the process.

Does the ratio of Helium atoms to Hydrogen atoms become larger as a star ages?
Yes, the ratio of helium atoms to hydrogen atoms does increase as a star ages. Stars undergo nuclear fusion reactions in their core, converting hydrogen into helium over time. This process increases the proportion of helium relative to hydrogen in the star's composition as it ages.
What is a fuel for a star?
Most stars process Hydrogen using nuclear fusion and turn it into Helium.
Why is the presence of large amount of helium in the spectrum of a star considered to be a sign of age?
Stars fuse hydrogen into helium, and then fuse the helium into carbon. For a star to have more than about 50% helium, we know that the star has already burned up half of its natural fuel, and that the end is near.
