Lay Summary (English)

Lead
Lay summary

Stellar evolution and ?nal explosive endpoints like supernovae are the main focus of the present proposal, which describes a continuing e?ort in explaining and understanding such astrophysical events and the composition of their ejecta. This includes several fundamental topics.

A: Stellar evolution, wind ejecta of rotating massive stars and low mass stars in terms of understanding their input into galactic chemical evolution.

B: Simulations of the final stages of core collapse and supernova explosions, combining (magneto-)hydrodynamics and radiation transport in 3D calculations of rotating and non-rotating progenitor stars.

C: Understanding of nuclear properties, reactions, the temperature-dependent high density equation of state, entering essentially all aspects of stellar physics from stellar evolution, core collapse and hydrostatic as well as explosive nucleosynthesis.

D: Explosive nucleosynthesis processes in the scenarios discussed above, covering all of the classical processes from typical hydrostatic burning, explosive burning and s-, p-. νp, and r-process, as well as burning which happens in binary systems involving a neutron star (X-ray bursts and neutron star mergers).

Stellar winds and stellar explosions serve as input to galactic evolution. Thus, this proposal covers a range from subatomic physics to the evolution of galaxies.

Abstract

Stellar evolution and ?nal explosive endpoints like supernovae are the main focus of the present proposal, which describes a continuing e?ort in explaining and understanding such astrophysical events and the composition of their ejecta. Several fundamental aspects are discussed in sections A to D. Section A features stellar evolution and wind ejecta of rotating massive stars, and also low mass stars, in terms of (a) understanding their input into galactic chemical evolution and (b) the composition of resulting dust grains which, if preserved, can be detected in meteoritic inclusions. A sideline examines accretion onto white dwarfs in binary stellar systems, aiming at a precise knowledge of the fuel composition of type Ia supernova progenitors. Section B describes simulations of core collapse and supernova explosions of massive stars, combining (magneto-) hydrodynamics and radiation transport in 3D calculations of rotating and non-rotating progenitors. Section C covers the understanding of nuclear properties, reactions, and aspects of temperature-dependent high density equations of state, i.e. nuclear features which enter stellar modeling. Section D finally focuses on explosive nucleosynthesis processes in the scenarios discussed above, covering all of the classical processes from typical hydrostatic burning, explosive burning, s-, p-. ?p, r-process, as well as the rp-process in X-ray bursts on neutron stars. Here we also address the question of highly precise, minimum-size reaction networks for the energy generation (and composition information) to be utilzed in the hydrodynamical modeling of such events. Stellar winds and stellar explosions serve as input to galactic evolution. Thus, this proposal covers physics from subatomic to the evolution of galaxies
