Impact of Sub-2.5 MeV 12C+12CResonances on the Production of Elements from C to Pd in Core-Collapse Supernovae
L. Roberti, S. Palmerini, A. Falla +10
We explore the impact of a more efficient 12C+12C reaction on the structure and nucleosynthesis of massive stars. We calculate non-rotating stellar models with initial masses of 15…
Production of heavy -elements and Ti in Cas A: comparison to abundances from 1D core-collapse supernova models and evidence for Carbon-Oxygen shell mergers
Luca Boccioli, Lorenzo Roberti, Chris L Fryer +3
The merger between the carbon (C) and oxygen (O) shells hours to days before the collapse of a massive star significantly changes its nucleosynthesis, which is reflected in the ele…
Explodability matters: how realistic neutrino-driven explosions change explosive nucleosynthesis yields
Luca Boccioli, Lorenzo Roberti
Explosive nucleosynthesis is affected by many uncertainties, particularly regarding assumptions and prescriptions adopted during the evolution of the star. Moreover, simple explosi…
Neutrino Heating in 1D, 2D, and 3D core-collapse supernovae: characterizing the explosion of high-compactness stars
Luca Boccioli, David Vartanyan, Evan P. O'Connor +1
Massive stars can end their lives with a successful supernova explosion (leaving behind a neutron star or, more rarely, a black hole), or a failed explosion that leaves behind a bl…
Quantifying the Impact of the Si/O Interface in CCSN Explosions Using the Force Explosion Condition
Luca Boccioli, Mariam Gogilashvili, Jeremiah Murphy +1
The explosion mechanism of a core-collapse supernova is a complex interplay between neutrino heating and cooling (including the effects of neutrino-driven convection), the gravitat…
Remnant masses from 1D+ core-collapse supernovae simulations: bimodal neutron star mass distribution and black holes in the low-mass gap
Luca Boccioli, Giacomo Fragione
The explosion of core-collapse supernovae (CCSNe) is an extremely challenging problem, and there are still large uncertainties regarding which stars lead to successful explosions t…
The physics of Core-Collapse Supernovae: explosion mechanism and explosive nucleosynthesis
Luca Boccioli, Lorenzo Roberti
Recent developments in multi-dimensional simulations of core-collapse supernovae have considerably improved our understanding of this complex phenomenon. In addition to that, one-d…
Explosion mechanism of core-collapse supernovae: role of the Si/O interface
Luca Boccioli, Lorenzo Roberti, Marco Limongi +2
We present a simple criterion to predict the explodability of massive stars based on the density and entropy profiles before collapse. If a pronounced density jump is present near…
Effect of the Nuclear Equation of State on Relativistic-Turbulence Induced Core-Collapse Supernovae
Luca Boccioli, Grant J. Mathews, In-Saeng Suh +1
The nuclear equation of state is an important component in the evolution of core collapse supernovae. In this paper we make a survey of various equations of state in the literature…
General Relativistic Neutrino-Driven Turbulence in One-Dimensional Core-Collapse Supernovae
Luca Boccioli, Grant J. Mathews, Evan O'Connor
Convection and turbulence in core-collapse supernovae (CCSNe) are inherently three-dimensional in nature. However, 3D simulations of CCSNe are computationally demanding. Thus, it i…
New Insights into Uncertainties in the Relic Neutrino Background and Effects from the Nuclear Equation of State
Grant J. Mathews, Luca Boccioli, Jun Hidaka +1
We review the computation of and associated uncertainties in the current understanding of the relic neutrino background due to core-collapse supernovae, black hole formation and ne…
