Fragmentation and clustering in star matter

open access: yesEPJ Web of Conferences, 2012
The specificity of the crust-core phase transition in neutron star at zero and finite temperature will be discussed. It will be shown that, as a consequence of the presence of long range Coulomb interactions, the equivalence of statistical ensembles is ...

arXiv:astro-ph/0203493

open access: yes, 2002
Spherically symmetric simulations of stellar core collapse and post-bounce evolution are used to test the sensitivity of the supernova dynamics to dierent variations of the input physics. We consider a state-of-the-art description of the neutrino-nucleon

Turbulence in Core-collapse Supernovae

open access: yesThe Astrophysical Journal
It is understood in a general sense that turbulent fluid motion below the shock front in a core-collapse supernova stiffens the effective equation of state of the fluid and aids in the revival of the explosion.

HD 271791: dynamical versus binary-supernova ejection scenario [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society: Letters, 2009
Abstract The atmosphere of the extremely high-velocity (530–920 km s−1) early B-type star HD 271791 is enriched in α-process elements, which suggests that this star is a former secondary component of a massive tight binary system and that its surface was polluted by the nucleosynthetic products after the primary star exploded in a ...

Effects of Rotation on 3D Core-collapse Supernova Models for Low-mass Progenitors

open access: yesThe Astrophysical Journal
We explore the dependence upon rotation rate alone of various supernova observables simulated to their saturation for the explosion of a 9 M _⊙ progenitor.

Late-time acceleration with steep exponential potentials

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
In this letter, we study the cosmological dynamics of steeper potential than exponential. Our analysis shows that a simple extension of an exponential potential allows to capture late-time cosmic acceleration and retain the tracker behavior.

Optimization of nonlinear function with planar regions using supernova [PDF]

open access: yes, 2018
Nowadays, optimization is begun to be use in different fields, e.g. preference algorithms. These new challenges need a robustness meta heuristics to solve them.

Alien Type Ia Supernovae from the Milky Way Merger History and One Possible Candidate: Kepler’s Supernova

open access: yesThe Astrophysical Journal
The Milky Way is a dynamic and evolving system shaped by numerous merger events throughout its history. These mergers bring stars with kinematic and dynamic properties differing from the main stellar population.

Inhomogeneous Stellar Mixing in the Final Hours before the Cassiopeia A Supernova

open access: yesThe Astrophysical Journal
Understanding stars and their evolution is a key goal of astronomical research and has long been a focus of human interest. In recent years, theorists have paid much attention to the final interior processes within massive stars, as they can be essential
