Projektbeschreibung
Neues über die Mechanismen des Massenverlustes bei massereichen Sternen
Massereiche Sterne sind kosmische Motoren, anhand denen Forschende das Universum – von der Sonnenumgebung bis zu Sternen, die in fernen Galaxien entstehen – untersuchen können. Trotz ihrer Bedeutung bleibt ihr Entwicklungsstadium von der Bildung bis zu ihrer Expansion und dem Zerfall unbekannt. Ziel des im Rahmen der Marie-Skłodowska-Curie-Maßnahmen geförderten Projekts POEMS ist der Aufbau eines multidisziplinären internationalen Netzwerks aus Forschenden aus Europa, Asien und Südamerika, die in verschiedenen Bereichen Expertise besitzen. Letztendlich sollen die Prozesse weiter beleuchtet werden, die für den Masseverlust bei massereichen Sternen in den letzten Entwicklungsstadien verantwortlich sind. Das Projektteam wird hochmoderne numerische Codes entwickeln, mit denen sich die chemische und dynamische Entwicklung der Sterne, ihrer Winde und ihrer umfangreichen Umgebungen beschreiben lassen.
Ziel
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.
