Constraining r-process nucleosynthesis with multi-objective Galactic chemical evolution models
M. Molero, A. Arcones, F. Montes +1
The astrophysical site(s) of the r-process are uncertain, with candidates such as neutron star mergers and magneto-rotational supernovae predicting different event rates, delay tim…

Taking the pulse of the outer Milky Way with HOWVAST: an RR Lyrae density profile out to 200 kpc
Gustavo E. Medina, Ricardo R. Muñoz, Jeffrey L. Carlin +4
In order to constrain the evolutionary history of the Milky Way, we hunt for faint RR Lyrae stars (RRLs) using Dark Energy Camera data from the High cadence Transient Survey (HiTS)…

Neutrino-Driven Outflows and the Elemental Abundance Patterns of Very Metal-Poor Stars
A. Psaltis, M. Jacobi, F. Montes +3
The elemental abundances between strontium and silver () observed in the atmospheres of very metal-poor stars (VMP) in the Galaxy may contain the fingerprint of the weak…
