"We know precisely the position of the Sun in our Galaxy. Yet, like for most stars,\r\nwe cannot tell where it was born. Stars undergo dynamical memory loss: their\r\norbits evolve, because the Milky Way, like many galaxies, has non-axisymmetric\r\nstructures (e.g. bar, spirals) that shuffle stellar orbits. My thesis quantifies the\r\nstrength of that process to answer: How (much) do stars change orbit? Can we still\r\ninfer their birth places, to constrain the formation of the Milky Way disk? I have\r\ncombined data from the large stellar surveys APOGEE and Gaia, and developed\r\na method to extract the information they contain on the Galactic disk evolution. I\r\nforward-modelled the formation of the stellar disk, the stars’ elemental abundances\r\nand their subsquent orbital diffusion, which then informs us about their birth radii\r\nthrough ’weak chemical tagging’. I have found that stars can change orbits by large\r\namounts, and most of this evolution is cold (the orbits stay near- circular). Secular\r\nevolution determines how the Milky Way disk is structued. If the Milky Way is\r\ntypical this explain what drives disk galaxies in general to their typical exponential\r\ndisk density profiles."^^ . "2021" . . . . . . . "Neige"^^ . "Frankel"^^ .
