WebThe Triple-Alpha Process. The fusion of hydrogen to helium by either the PP chain or the CNO cycle requires temperatures of the order of 10,000,000 K or higher, since only at those temperatures will there be enough hydrogen ions in the plasma with high enough … http://csep10.phys.utk.edu/OJTA2dev/ojta/c2c/ordinary_stars/stages/alpha_tl.html problems with wellcare insuranceWebThe Triple-alpha Process is inefficient at producing energy, so it can only last for about 100 Myr. There is less energy for every gram of material fused, partially because of neutrinos being produced, and partly because of the physics of nuclei. You just get less total energy from this process than you do from the PP chain or the CNO cycle. problems with well water pressure

"WebTHE TRIPLE-ALPHA PROCESS This nuclear reaction fuses 3 HELIUM NUCLEI into 1 CARBON NUCLEUS and releases energy. He 4 + He 4 <==> Be 8 + photon Be 8 + He 4 ==> C 12 + photon The beryllium (Be) is very unstable and will break apart very quickly (3 x 10 -16 seconds!) unless it is hit by another helium to form carbon.

WebThe Triple-alpha Process is very inefficient at producing energy, so it can only last for about 100 Myr. While it goes on, the star steadily builds up a C-O core, but it is still too cool to ignite Carbon fusion Asymptotic Giant Branch Phase After 100 Myr, the core runs out of Helium for Triple-Alpha fusion. Inside: C-O core collapses and heats up WebThis process, mediated by the strong nuclear force rather than the weak force, is extremely fast by comparison to the first step. It is estimated that, under the conditions in the Sun's core, each newly created deuterium nucleus exists for only about one second before it is converted into helium-3. [1]

WebThe triple alpha process for post-main sequence stars. Two helium nuclei (alpha-particles) fuse to form a beryllium-8 nucleus. This is unstable and normally decays back into two H-4e nuclei within a fraction of a second but given the high number of He-4 nuclei in the core will sometimes collide with one before it has had a chance to decay.
