Explosive nucleosynthesis runs through exotic nuclei
Nuclear shell structure- Defines r-process path- Imprinted in abundance pattern
- Fission may fill the holes- Depends on shell structure as well
Facilities for radioactive ion beams: Access to properties of r-process nuclei Towards a unified description of nuclei(today: CERN/ISOLDE, GSI Darmstadt, ILL Grenoble;Future: FAIR (Darmstadt), RIBF (Japan)
r - process
Facility for Antiproton and Ion Research - FAIR

Secondary Beams
• Broad range of radioactive beams
up to 1.5 - 2 GeV/u; • up to factor 10 000 in intensity over present
• Antiprotons 3 - 30 GeV
Reach of mass measurements
How are the heavy elements formed in such explosions?
GOALS:Development of improved model predictions of
nucleosynthesis cross-checked against observations of large scale surveys and of individual events
Models by MPAObservations by MPE, ESO
Improved understanding of shell structure of very exotic nuclei involved in explosive nucleosynthesis
Laboratory experiments by MLL (LMU, TUM)Nuclear theory by MLL (LMU, TUM) GSI
New W2 Professorship for experimental Nuclear Astrophysics
Starformation
Ejection of metalsFormation of
metal-enrichedgas clouds
How are the ejected elements mixed into the interstellar and intergalactic medium and incorporated into newly formed stars?

Turbulence and molecular cloud formation
How are the ejected elements mixed into the interstellar and intergalactic medium and incorporated into newly
formed stars?
GOAL:
Development of improved models of molecular cloud and star formation
Simulations by LMU/USMTurbulence Theory by IPP
Observations by MPE, MPA, ESO
New Junior Research Group: First light and chemical enrichment of the Universe
How did the nuclear composition of galaxies evolve with time?
Formation and chemical Evolution of galaxies – matching models and observations –
How did the nuclear composition of galaxies evolve with time?
GOALS:
High precision observational data on element specific abundances through large surveys
Analysis of observational data by ESO, MPA, MPE
Improved models of galactic evolution and their chemical enrichment
Large scale simulations of chemical evolution of galaxies by MPA
Summary
Goal for the next 5 years:
Better understanding of
the enrichment of the universe with heavy elements
by
interlinking and enhancing the existing expertise in
modeling, observations, and laboratory experiments
