    B CNO Cycle

    Dear PF Forum, What is CNO Cycle? Is it Carbon Nitrogen Oxygen cycle or Carbon Neon Oxygen? Veritasium CNO cycle In this video, Derek Muller says that Carbon fuses into Neon, and Neon fuses into Oxygen. I can't imagine that Derek makes an error here. But for myself, I get a little confused...

    A What is the energy release of the CNO cycle in carbon fusion?

    I would like details on CNO Cycle Carbon Fusion about the exact energy release of an entire cycle through the reaction and other details you would think would be important about the CNO cycle.

    I Why is H burning not a B+ decay

    Hello physics gurus out there. Can someone please point me in the correct direction. I am looking for reasons why Hydrogen burning is NOT considered to be B+ decay in the standard CNO cycle? Thanks The forgetful one

    CNO fusion using particle accelerator?

    The CNO cycle (see https://en.wikipedia.org/wiki/CNO_cycle) is a catalytic fusion reaction that produces energy in stars larger than the sun. It converts four protons into a helium-4 nucleus using a cycle of carbon, nitrogen and oxygen isotopes as catalysts and releases 26.7 MeV of energy mostly...

    Star Nuclear Reaction: P+P, D+P, He3 and CNO Cycle

    Dear PF Forum, I'm just wondering about P+P reaction in star. Because of its pressure, in the core of the star, hydrogens fuse to become deuterium. Its the complete reaction P + P -> D D + P -> He3 He3 + He3 -> He3 + P + P and if the star is big enough, it can undergo CNO cycle, But what if...

    Is This Picture Really About the CNO Cycle?

    Dear PF Forum, Is this picture correct? Or it is not CNO Cycle? I get that video from this Thanks for any answer

    CNO Cycle: Understanding the Last Reaction and the Mystery of 16O

    The last reaction in CNO-I sees 15N + 1H --> 12C + 4He I'm interested why it doesn't produce 16O, which is also stable.

    In the CNO cycle, how does Nitrogen-15 become Carbon-12 and Helium-4?

    Homework Statement I understand the rest of the cycle, the way my textbook has it, which is: 12C→13N→13C→14N→15O→15N→12C+4He The portion in bold is what I don't understand. Homework EquationsThe Attempt at a Solution I do understand that when the mass number increases (like from Carbon-13 to...

    Is CNO cycle more life friendly than H->He?

    Wiki claims in stars, heavier than 1.3 solar masses (where CNO plays major role) there is an inner convection zone near the core, but no outer convection zone. Hence, such stars should be "calmer" - no solar flares, less radiation... Am I right?

    Cno cycle dense plasma focus fusion

    hello, new to site. This is my first post. I just was wondering what any ones thoughts were on using the carbon, nitrogen, oxygen cycle in a dense plasma focus device to produce aneutronic fusion power.
