Approche numérique de la dynamique et de l'évolution stellaires appliquées à la fusion galactique

Abstract : This thesis explore the influence of stellar and galactic scales on young star clusters observations. A complete study of the mass segregation phenomenon has been conducted to quantify the induced observational bias when estimating mass from the virial theorem. The development of ruby libraries linking stellar evolution routines and a spectral library to the analysis made the result possible. The Antennae system has been reproduced to investigate the influence of galactic scales. The tidal tensor experienced along a cluster orbital path has been retrieved and its implications explored. Totally compressive zones that could trigger cluster formation or prevent early dissolution have been highlighted and the inclusion of this method in a direct summation code done.
