QUÍMICA ESTELAR E ESTRELAS APOCALÍPTICAS: ESTUDO COMPARATIVO
Colloquium Exactarum, 2012 All atoms existing in the Universe, except Hydrogen (H) and helium (He), arise from processes occurring in stars and their evolution. The stars transmute the H and He in other heavier elements through nuclear fusion and its process rolling, filling and ...

Dynamics of a Supernova Envelope in a Cloudy Interstellar Medium [PDF]
, 2015 The evolution of a supernova remnant in a cloudy medium as a function of the volume filling factor of the clouds is studied in a three-dimensional axially symmetrical model.

Ghost particles in the universe: Neutrinos in astrophysics and cosmology
Mètode Science Studies Journal: Annual Review, 2017 Neutrinos are nearly massless and very difficult to detect because they interact so very weakly. Sixty years after seeing the first of these «ghost particles» we know a lot about their properties.

First Observations of SN 1604 (Kepler’s Supernova)
Universe, 2021 A supernova close enough to the Earth is a spectacular event: it can appear as a “new star” as luminous as Venus, or even more, visible for several days.

Symmetry energy impact in simulations of core-collapse supernovae [PDF]
, 2014 We present a review of a broad selection of nuclear matter equations of state (EOSs) applicable in core-collapse supernova studies. The large variety of nuclear matter properties, such as the symmetry energy, which are covered by these EOSs leads to ...

Significance of neutrino-neutrino interaction in neutrino oscillation in core-collapse supernova
Bibechana, 2014 We study the possibility of neutrino-neutrino interaction inside the neutrino core of supernova (ρ ≥ 1010 g/cc) and outside the neutrinosphere. The angular dependence of the neutrino-neutrino interaction Hamiltonian causes multi-angle effects that can ...

Variable G versus the Accelerated Expansion of the Universe
Open Astronomy, 2017 It is shown that the hypothesis of permitting variability of the Newtonian constant G, increasing with the local density of dark matter, implies that there is no need for the introduction of a cosmological constant or accelerated expansion of the ...

Observational data on Galactic supernova remnants III: The supernova remnants within l = 270°-360° [PDF]
Serbian Astronomical Journal, 2004 We have collected all the available data of Galactic supernova remnants given in the literature. The data of Galactic supernova remnants located in the Galactic longitude interval l=270°-360°in all the spectral bands are represented in this work. We have

Limit on Supernova Emission in the Brightest Gamma-Ray Burst, GRB 221009A
The Astrophysical Journal Letters, 2023 We present photometric and spectroscopic observations of the extraordinary gamma-ray burst (GRB) 221009A in search of an associated supernova. Some past GRBs have shown bumps in the optical light curve that coincide with the emergence of supernova ...
