Comparisons for ESTA-Task3: CLES and CESAM

Comparisons for Esta-task3: Cles and Cesam

We present the results of comparing three different implementations of the microscopic diffusion process in the stellar evolution codes CESAM and CLES. For each of these implementations we computed models of 1.0, 1.2 and 1.3 M⊙. We analyse the differences in their internal structure at three selected evolutionary stages, as well as the variations of helium abundance and depth of the stellar con...

Task3 Patient-Centred Information Retrieval: Team CUNI

In this paper we present our participation as the team of the Charles University at Task3 Patient-Centred Information Retrieval. In the monolingual task and its subtasks, we submitted two runs: one is based on language model approach and the second one is based on vector space model. For the multilingual task, Khresmoi translator, a Statistical Machine Translation (SMT) system, is used to trans...

CESAM: a free code for stellar evolution calculations

The cesam code is a consistent set of programs and routines which perform calculations of 1D quasi-hydrostatic stellar evolution including microscopic diffusion of chemical species and diffusion of angular momentum. The solution of the quasi-static equilibrium is performed by a collocation method based on piecewise polynomials approximations projected on a B-spline basis; that allows stable and...

Grids of stellar evolution models for asteroseismology (CESAM + POSC)

In this paper we present a grid of stellar evolution models, computed with an up-to-date physical description of the internal structure, using the Code d’Évolution Stellaire Adaptatif et Modulaire (CESAM). The evolutionary sequences span from the pre-main sequence to the beginning of the Red Giant Branch and cover an interval of mass typical for low and intermediate mass stars. The chemical com...
