Resumen en inglés

The study of the distribution of molecules in star forming regions helps to constrain the chemical models. The "mini-starburst" region associated to W43-MM1 includes a number of massive pre-stellar and proto-stellar cores candidates (e.g. tealt{Motte18, nony18}). It is an important sample of molecular cores at various evolutionary stages and moreover, it may contain the most massive cold core known in the whole Galaxy. We present high spatial resolution data from ALMA Cycle 2 and Cycle 3. We first introduce the technique we developed to substract automatically the continuum in large regions of molecular emission in order to study weak emission lines. Then we present the current state of our comparison of the molecular composition of the cores in W43-MM1, in particular between two high-mass cores of similar masses and sizes.< Leer menos
