Description du projet
Découvrir les mécanismes de perte de masse des étoiles massives
Les étoiles massives sont des moteurs cosmiques qui permettent aux chercheurs d’étudier l’univers, depuis le voisinage solaire jusqu’aux étoiles en formation dans de lointaines galaxies. Malgré leur importance, leur stade d’évolution – de leur formation à leur expansion et à leur effondrement – reste inconnu. Financé par le programme Actions Marie Skłodowska-Curie, le projet POEMS a pour objectif d’établir un réseau international pluridisciplinaire de chercheurs d’Europe, d’Asie et d’Amérique du Sud, experts dans divers domaines. L’objectif ultime sera d’apporter un éclairage nouveau sur les processus qui provoquent la perte de masse des étoiles massives au cours des derniers stades de leur évolution. Le projet développera des codes numériques de pointe pour décrire l’évolution chimique et dynamique des étoiles, leurs vents et leurs environnements à grande échelle.
Objectif
Massive stars are extreme cosmic engines, enriching their environments with chemically processed material throughout their entire life-time, and triggering star and planet formation. Despite their importance for the cosmic evolution, their evolutionary path up to their deaths as spectacular supernova explosions is most uncertain due to the lack of precise knowledge of the physical mechanisms behind mass eruptions. We wish to establish a multidisciplinary, international network of researchers from Europe, Asia, and South America with expertise in a variety of disciplines, and with background in both theory and observations. Our ultimate goal is to enlighten the processes that trigger mass loss in massive stars during extreme phases of their evolution. We will develop cutting-edge numerical codes suitable to describe the chemical and dynamical evolution of the stars, their winds, and their large-scale environments. In addition, we will initiate global observing campaigns utilizing facilities at major renowned observatories in combination with our national facilities, and exploit public archives from ground-based and space missions to acquire an outstanding set of urgently needed highest quality data. Confronting predictions from the numerical models with the observations will empower us to derive the first extensive and comprehensive set of precise physical parameters. The acquired results will significantly enhance our knowledge and lead to major advancements in all related fields. The bulk of exchanges will be undertaken by Early Stage Researchers and young Post-docs, who will be educated and trained in modern observing and data analyzing techniques and in high-performance computation, equipping them with excellent skills for their future careers. We will organize schools and workshops to share knowledge and to communicate and disseminate our results, which will be major breakthroughs and support the leading role of Europe in Astronomy.
