In spite of their pivotal role in observational cosmology and and in the determination of the chemical composition of matter in the Universe, Type Ia SNe Ia still represent an intriguing mystery. In fact, up to now no clear consensus there exists concerning their progenitor systems and the explosion mechanism.

Superbursts are very energetic explosions occurring at the outer crusts of neutron stars, as a consequence of unstable carbon burning . They release up to $10^{40}$ erg in a span of hours/days and have recurrence times in the order of years. In contrast to the standard, less-energetic bursts due to H/He burning, only a few multi-zone simulations have been reported. While these pioneering works...

The progenitor systems of normal type Ia supernovae (SNe Ia) remain a central puzzle. The long-debated single-degenerate (SD) channel, where a white dwarf (WD) accretes mass from a companion, faces major observational conflicts. The unknown rising form the carbon ignition and detonation mechanism in sub-Chandrasekhar mass led us to run 3D hydrodynamic simulations that address these tensions by...

In this contribution, we present an overview of the measurements of the $^{12}$C+$^{12}$C fusion reaction conducted with the mobile measurement station STELLA (STELlar LAboratory). This apparatus is designed for fusion studies involving light heavy ions and has been employed for carbon fusion measurements at Andromède, IJCLab (Orsay) and at the Felsenkeller shallow underground laboratory...

The oscillations in the excitation function of $^{12}$C+$^{12}$C, from energies above the Coulomb barrier down to the astrophysical region, is believed to be associated to molecular states in the compound nucleus [1], or linked to the fusion dynamics. Cluster states has been identified for example in $^{24}$Mg near subsystems breakup threshold, as $^{12}$C+$^{12}$C and...

Carbon burning is a crucial stage of stellar evolution, determining whether stars evolve

toward neutron stars, black holes, or CO white dwarfs. These outcomes depend strongly on
the (^{12})C+(^{12})C reaction rate, which is still uncertain at astrophysical energies.
This reaction mainly proceeds through the (^{12})C((^{12})C,(\alpha))(^{20})Ne and
(^{12})C((^{12})C,p)(^{23})Na channels.... -

A Bayesian analysis of the modified astrophysical factor S∗(E) for the 12C + 12C fusion reaction is presented using available data at carbon–carbon energies Ecm < 3.5 MeV, including direct measurements, Coulomb-renormalized Trojan Horse Method results, and recent inverse-kinematics data.

The nuclear structure of $^{24}$Mg in the excitation energy region relevant to the $^{12}$C+$^{12}$C fusion reaction is crucial for constraining carbon-burning processes in massive stars. Although this reaction has been extensively studied over the past decades, significant uncertainties persist, particularly at center of mass energies below 2.5 MeV, where direct measurements are hindered by...

The $^{12}$C + $^{16}$O reaction plays a particularly important role in both the carbon and oxygen-burning phases of stars. Fang et al. measured this reaction in a thick-target experiment a few years ago, with both singles and particle-γ coincidence techniques down to a few nanobarns. However, the lowest energy points suffer from large experimental uncertainties which prevent discriminating...

Low-energy $^{12}\mathrm{C}+^{12}\mathrm{C}$ fusion reactions play a crucial role in astrophysical phenomena such as X-ray superbursts (XRSBs), the evolution of massive stars, and Type Ia supernovae. In this reaction, resonance contributions dominate the fusion cross section, and channel-coupling effects are expected to be essential.
We theoretically investigate the...
