“…The Argonne results [7] appear to be in a qualitative agreement with classical coupled-channel CC-M3Y+Rep calculations in [10], TDWP calculations of [11], the barrier penetration model of [12] and more recent theoretical investigations in [13]. Based on Fig.…”

“…The standard 12 C+ 12 C reaction rate was established by Caughan and Fowler [9]. Their simple extrapolation agrees reasonably with some recent theoretical calculations, such as CC-M3Y+Rep [10], TDWP [11] and barrier penetration model based on the global Sáo Paulo potentials (SPP) [12], see Fig. 1, as well with sophisticated coupledchannels calculations [13,14] and recent Hartree-Fock and time-dependent Hartree-Fock calculations [15].…”

“…The assigned in [8] spin 1 − for the resonance at 0.877 MeV is a mistake because a resonance with negative parity cannot be populated in the collision of two identical bosons such as 12 MeV, which is inside the Gamow window, is of a crucial importance for the 12 C − 12 C fusion rates and will play the same role as the "Hoyle" state [29] in the triple-α process of synthesis of 12 C [30]. Note that the models using the global potentials in [10,11,31,32] can predict resonances only above E = 2.5 MeV (the TDHF calculations of [15] do not take into account any possible resonant behavior in the fusion process). The THM data at low energies call for an improvement of the theoretical models.…”

Since the discovery of molecular resonances in 12 C+ 12 C in the early sixties a great deal of research work has been undertaken to study α-clustering and resonant effects of the fusion process at sub-Coulomb barrier energies. The modified astrophysical S * factors of 12 C+ 12 C fusion have been extracted from direct fusion measurements at deep sub-barrier energies near the Gamow window. They were also obtained by the indirect Trojan horse method (THM). A comparison of direct measurements and the THM, which elucidates problems in the analysis of the THM, is discussed in this Letter to the Editor.

A century ago, nuclear physics entered astrophysics, giving birth to a new field of science referred to as "Nuclear Astrophysics". With time, it developed at an impressive pace into a vastly inter-and multidisciplinary discipline bringing into its wake not only astronomy and cosmology, but also many other sub-fields of physics, especially particle, solid-state and computational physics, as well as chemistry, geology and even biology. The present Astronuclear Physics review focusses primarily on the facets of nuclear physics that are of relevance to astronomy and astrophysics, the theoretical aspects being of special concern here. The observational aspects of astronomy and astrophysics that may have some connection to nuclear physics are only broadly reviewed, mainly through the provision of recent relevant references. Multi-messenger astronomy has developed most remarkably during the last decades, with often direct implications for nuclear astrophysics. The electromagnetic view of the components of the Universe has improved dramatically at all wavelengths, from the γ-ray to the radio domains, providing important new information on the Big Bang and the properties of stars. Neutrino astronomy has made giant steps forward. In particular, the famed "solar neutrino problem" is now behind us. The long-sought gravitational waves have at last been detected, with direct relevance namely to the merger of compact stars. The composition of Galactic Cosmic Rays and stellar/solar energetic particles is better known than ever, providing constrains on the GCR physics.On the stellar modeling side, we broadly brush the progress that has been made based on new observations, and even more so on the spectacular increase in computer capabilities. We briefly outline recent advances regarding the quiescent evolution of stars, as well as the eventual catastrophic supernova explosion of certain classes of them. In spite of significant improvements in the simulations, many long-standing problems still await solid solutions, particularly regarding the details and robustness of explosion simulations. In fact, new questions are continuously emerging, and new facts may endanger old ideas.The lion's share of this review concerns the nuclear physics phenomena that may be at work in astrophysical conditions, with a strong focus on theory. Exceptionally large varieties of nuclei have to be dealt with, ranging from the lightest to the heaviest ones, from the valley of nuclear stability all the way to the proton and neutron drip lines. An additional serious difficulty comes from the fact that the nuclei are immersed in highly unusual environments which may have a significant impact on their static properties, the diversity of their transmutation modes, some of which not being observable in the laboratory, and on the probabilities of these modes. The description of nuclei as individual entities has even to be replaced by the construction of an Equation of State at high enough temperatures and/or densities prevailing in the cores of exploding stars an...
