Mean proton and alpha-particle reduced widths of the Porter-Thomas distribution and astrophysical applications
Pogrebnyak, I.; Howard, C.; Iliadis, Christian; Longland, Richard Leigh; Mitchell, G.E. (2013-07)
Article
Accés obertThe Porter-Thomas distribution is a key prediction of the Gaussian orthogonal ensemble in random matrix theory. It is routinely used to provide a measure for the number of levels that are missing in a given resonance ... -
Nucleosynthesis during the merger of white dwarfs and the origin of R Coronae Borealis stars
Longland, Richard Leigh; Lorén Aguilar, Pablo; José Pont, Jordi; García-Berro Montilla, Enrique; Althaus, Leandro Gabriel; Isern Vilaboy, Jordi (2011-08-20)
Article
Accés restringit per política de l'editorialMany hydrogen-deficient stars are characterized by surface abundance patterns that are hard to reconcile with conventional stellar evolution. Instead, it has been suggested that they may represent the result of a merger ... -
On the parallelization of stellar evolution codes
Martin Rodriguez, David; José Pont, Jordi; Longland, Richard Leigh (Springer (Biomed Central Ltd.), 2018-11-01)
Article
Accés obertMultidimensional nucleosynthesis studies with hundreds of nuclei linked through thousands of nuclear processes are still computationally prohibitive. To date, most nucleosynthesis studies rely either on hydrostatic/hydrodynamic ... -
Reaction rates for the s-process neutron source Ne-22+alpha
Longland, Richard Leigh; Iliadis, Christian; Karakas, A.I. (2012-06-25)
Article
Accés obertThe 22Ne(α, n)25Mg reaction is an important source of neutrons for the s-process. In massive stars responsible for the weak component of the s-process, 22Ne(α, n)25Mg is the dominant source of neutrons, both during core ... -
White dwarf mergers and the origin of R coronae borealis stars
Lorén Aguilar, Pablo; Longland, Richard Leigh; José Pont, Jordi; García-Berro Montilla, Enrique; Althaus, Leandro Gabriel; Isern-Fontanet, J. (2012)
Text en actes de congrés
Accés restringit per política de l'editorialWe present a nucleosynthesis study of the merger of a 0.4 M⊙ helium white dwarf with a 0.8 M⊙ carbon-oxygen white dwarf, coupling the thermodynamic history of Smoothed Particle Hydrodynamics particles with a post-processing ...
