In stars with temperatures above 20·10 K, hydrogen burning is dominated by the CNO cycle. Its rate is determined by the slowest process, the N(p,γ)O reaction. Deep underground in Italy’s Gran Sasso laboratory, at the LUNA 400 kV accelerator, the cross section of this reaction has been measured at energies much lower than ever achieved before. Using a windowless gas target and a 4π BGO summing d...

The author applies, develops and researches mini-sized MicroAB Thermonuclear Reactors for space propulsion and space power systems. These small engines directly convert the high speed charged particles produced in the thermonuclear reactor into vehicle thrust or vehicle electricity with maximum efficiency. The simplest AB-thermonuclear propulsion offered allows spaceships to reach speeds of 20,...

We study primordial nucleosynthesis in hypothetical hot regions that could be formed by the density inhomogeneities. It is shown survived up to present times acquire an abnormally high metallicity. This conclusion holds a wide range of initial parameters such regions. considered thermonuclear reaction rates and estimated abundances deuterium helium-3 -4 inside these areas. has been established ...

Big Bang Nucleosynthesis (BBN) is an important stage of a homogeneous and isotropic expanding universe. The results calculation the synthesis light elements during this epoch can then be compared with abundances elements. theoretical BBN model depends on initial conditions early universe reaction cross sections measured by nuclear physics experiment. Recently, update NACRE (Nuclear Astrophysics...

The response of lean (φ 0.4) premixed hydrogen flames to maintained homogeneous isotropic turbulence is investigated using detailed numerical simulation in an idealised three-dimensional configuration over a range of Karlovitz numbers from 10 to 1562. In particular, a focus is placed on turbulence sufficiently intense that the flames can no longer be considered to be in the thin reaction burnin...

The nucleosynthesis and other observable consequences of a nova outburst depend sensitively on the details of the thermonuclear runaway which initiates the outburst. One important source of uncertainty in our current models is the nuclear reaction data used as input for the evolutionary calculations. We present preliminary results of the first analyses of the impact on nova nucleosynthesis of a...

Neutron stars, with their strong surface gravity, have interestingly short timescales for the sedimentation of heavy elements. Recent observations of unstable thermonuclear burning (observed as X-ray bursts) on the surfaces of slowly accreting neutron stars (< 0.01 of the Eddington rate) motivate us to examine how sedimentation of CNO isotopes affects the ignition of these bursts. We further es...

Resonance exhibits a dynamo mechanism of the Sun with an exotic behavior of a controlled thermonuclear fusion reaction in the presence of a magnetic mirror. A charged oscillator takes place of a periodic driving force so that the laser radiation is so intense with the growing of a magnetic field towards the resonant level. Following the representation of a new era of a magnetic field, it has ma...
