Résumé :

In this contribution talk, I will introduce the novel galaxy modelling algorithm called GravPot16 (https://fernandez-trincado.github.io/GravPot16/), a dynamical tool originally developed in Besancon under support of the CNES and continuously improved under support of the Chilean Fondecyt. The algorithm was build-up to make a new dynamical model of the Milky Way complemented with the Besancon Galaxy model. GravPot16 is a state-of-the art orbital integration model with an (as far as possible) realistic gravitational potential, with an emphasis on the use of data from the Gaia mission along with other complimentary spectroscopic survey data, like APOGEE-2/SDSS-IV. Here, I will present the more relevant researches using GravPot16.
