Descrizione del progetto
Scoprire i meccanismi della perdita di massa nelle stelle massicce
Le stelle massicce sono motori cosmici che consentono ai ricercatori di studiare l’universo, dalla zona intorno al Sole alle stelle che si formano in galassie lontane. Nonostante la loro importanza, il loro stadio evolutivo, dalla loro formazione fino alla loro espansione e collasso, rimane sconosciuto. Finanziato dal programma di azioni Marie Skłodowska-Curie, il progetto POEMS mira a creare una rete internazionale multidisciplinare di ricercatori provenienti da Europa, Asia e Sud America con esperienza in una varietà di campi. L’obiettivo finale è quello di gettare ulteriore luce sui processi che innescano la perdita di massa nelle stelle massicce durante le ultime fasi dell’evoluzione. Il progetto svilupperà codici numerici all’avanguardia per descrivere l’evoluzione chimica e dinamica delle stelle, dei loro venti e dei loro ambienti su larga scala.
Obiettivo
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.
