Mn abundances in the stars of the Galactic disc with metallicities -1.0 < [Fe/H] < 0.3
T. Mishenina, T. Gorbaneva, M. Pignatari +2
In this work we present and discuss the observations of the Mn abundances for 247 FGK dwarfs, located in the Galactic disc with metallicity -1<Fe/H]<+0.3. The observed stars belong…
A primordial r-process?
T. Rauscher, J. H. Applegate, J. J. Cowan +2
Baryon density inhomogeneities in the early universe can give rise to a floor of heavy elements (up to ) produced in a primordial r-process with fission cycling. A pa…
Primordial heavy element production
T. Rauscher, F. -K. Thielemann
A number of possible mechanisms have been suggested to generate density inhomogeneities in the early Universe which could survive until the onset of primordial nucleosynthesis and…
The LOFT perspective on neutron star thermonuclear bursts
J. J. M. in 't Zand, D. Altamirano, D. R. Ballantyne +31
This is a White Paper in support of the mission concept of the Large Observatory for X-ray Timing (LOFT), proposed as a medium-sized ESA mission. We discuss the potential of LOFT f…
Galactic evolution of rapid neutron capture process abundances: the inhomogeneous approach
B. Wehmeyer, M. Pignatari, F. -K. Thielemann
For the origin of heavy r-process elements, different sources have been proposed, e.g., core-collapse supernovae or neutron star mergers. Old metal-poor stars carry the signature o…
Pushing 1D CCSNe to explosions: model and SN 1987A
A. Perego, M. Hempel, C. Fröhlich +5
We report on a method, PUSH, for triggering core-collapse supernova explosions of massive stars in spherical symmetry. We explore basic explosion properties and calibrate PUSH such…
