supernovar-processWe have calculated r-process nucleosynthesis based on acoustic wave driven supernova simulation. The environment includes extremely high entropy cases which has not been studied in previous studies. Plenty of actinide and third peak elements are formed in an averaged abundance, while...
supernova- a star that explodes and becomes extremely luminous in the process star- (astronomy) a celestial body of hot gases that radiates energy derived from thermonuclear reactions in the interior Based on WordNet 3.0, Farlex clipart collection. © 2003-2012 Princeton University, Farlex Inc....
The r -process in Type II supernovae has been examined using a semianalytic, general relativistic model of neutrino winds and a nuclear reaction network code. We found that the relatively high entropy ( \\(\\sim 140N_{A}k\\) ) was obtained for the model of a massive proto-neutron ...
erence ∆m2 in the process discussed above.However, it has been pointed out that [21] these bounds could be invalid if the resonant re-conversion of neutrinos take place in the supernova.
<italic>Aims. </italic>We study the production of dust in Type II-P supernova ejecta by coupling the gas-phase chemistry to the dust nucleation and condensation phases. We consider two supernova progenitor masses with homogeneous and clumpy ejecta to ass
<italic>Context. </italic>It is widely accepted that the onset of the explosive carbon burning in the core of a carbon-oxygen white dwarf (CO WD) triggers the ignition of a type Ia supernova (SN Ia). The features of the ignition are among the few free pa

These supernovae are further subdivided into finer classes based on their spectra and light curves [see, e.g., Ref. [4]], as shown in Fig. 1 and Fig. 2. Not shown on these diagrams are the super-luminous SNe, including the pair-instability SNe (PISN), which may or may not show...
supernovae: generaltechniques: spectroscopic(Abridged) The presence of unburned material in the ejecta of normal Type Ia supernovae (SNeIa) is investigated using early-time spectroscopy obtained by the CSP. The tell-tale signature of pristine material from a C+O white dwarf progenitor star is ...
