r-Java: anr-process code and graphical user interface for heavy-element nucleosynthesis

Abstract: We present r-Java, an r-process code for open use that performs r-process nucleosynthesis calculations. Equipped with a simple graphical user interface, r-Java is capable of carrying out nuclear statistical equilibrium (NSE), as well as static and dynamic r-process calculations, for a wide range of input parameters. In this introductory paper, we present the motivation and details behind r-Java and results from our static and dynamic simulations. Static simulations are explored for a range of neutron irradiati… Show more

“…The factor F depends on the initial mass-fraction distribution used and of the environment. 43,51,[58][59][60] The r-java code [43][44][45] requires a large number of variables as input, namely: astrophysical and nuclear variables like T 0 (the initial temperature), ρ 0 (density profile), Vexp (expansion velocity), R 0 (initial radii), among others. Each of the calculations gives different values for the scaling factor F of Eq.…”

“…To perform the calculations we have chosen the r-java2.0 code, developed by the Calgary University group. [43][44][45] This code solves the nuclear r-process network coupled to an astrophysical scenario. We have modified the inputs of the code to include the βdecay rates of Eq.…”

“…Es decir f = dΓ osc dΓ no−osc (6.66) Modificamos las velocidades de decaimiento (en s −1 ) de 8055 elementos e isótopos necesarios para calcular la evolución de las abundancias del proceso-r, mediante la multiplicación por el factor de cambio f , de manera que dΓ N osc = f dΓ N no−osc . Las velocidades de decaimiento del neutrón libre sin contemplar oscilaciones dΓ no−osc así como las de los decaimientos de los diferentes núcleos dΓ N no−osc fueron extraídas de los trabajos de Moller [181,182], y son las que utiliza el código r-java por defecto [183,184,185]. dΓ N osc son las velocidades de decaimiento de los núcleos cuando las oscilaciones son consideradas.…”
