Descripción del proyecto
Descubriendo los mecanismos de pérdida de masa en estrellas masivas
Las estrellas masivas son motores cósmicos que permiten a los investigadores estudiar el universo, desde el entorno solar hasta estrellas que se forman en galaxias distantes. A pesar de su importancia, se desconoce su etapa evolutiva, desde su formación hasta su expansión y colapso. El proyecto POEMS, financiado por las Acciones Marie Skłodowska-Curie, se creó con el fin de establecer una red internacional multidisciplinaria de investigadores de Europa, Asia y América del Sur con conocimientos sobre varios campos. El objetivo es aclarar los procesos que desencadenan la pérdida de masa en estrellas masivas durante las últimas etapas de su evolución. El proyecto desarrollará códigos numéricos vanguardistas para describir la evolución química y dinámica de las estrellas, sus vientos y sus entornos a gran escala.
Objetivo
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.
