- Yo! you called me to help you on something right?
- Yeah sure, I'll help you on that.
- what research?
- It's something abouthydrogen heliumburning in physical science. I'll just explain the 2 and you check if it's right.
- Yeah, I need you to check on my research if it's good.
- Ok so first, hydrogen burning, This first stage begins with the proton-proton cycle, otherwise known as the proton-proton chain where hydrogen is converted to helium. This process dominates in stars that have a similar mass to the Sun. When the energy is sufficient to overcome the electrostatic or Coulomb repulsion forces among the protons, the fusion takes place...
- yeah and if I remember correctly, This process is made by stars less than or equal to one solar mass. So by fusing two hydrogen atoms yield a neutron-containing deuterium--
- , a positron, and a neutrino. Subsequent fusion with hydrogen yields Helium 3, and a gamma ray in the form of a photon. Fusing two 3He gives two 1H and 4He. Something like that.
- so it's like, the electrostatic force of repulsion exerted by one charged particle on another charged particle of the same sign?
- Alright, and as for helium burning?
- Is the second stage begins after most of the hydrogen is burned, which is around this time a main sequence star turns into a Red Giant. Helium burning is done either through the alpha process or the triple-alpha process. In the triple-alpha process, two helium-4 (4He) nuclei or alpha particles fuse to form 8Be (Beryllium-8)
- Yeah seems about right.and I think your research sounds fine to me.
- Fusing it with another alpha particle yields a carbon nucleus. As soon as carbon is present, the alpha process begins where the formation of neon, oxygen and silicon takes place.
