Unusual neutron-capture nucleosynthesis in a carbon-rich Galactic bulge star
A. Koch, M. Reichert, C. J. Hansen +4
Metal-poor stars in the Galactic halo often show strong enhancements in carbon and/or neutron-capture elements. However, the Galactic bulge is notable for its paucity of carbon-enh…
ATHOS: On-the-fly stellar parameter determination of FGK stars based on flux ratios from optical spectra
Michael Hanke, Camilla Juul Hansen, Andreas Koch +1
Tools for the spectroscopic determination of fundamental stellar parameters should not only comprise customized solutions for one particular survey or instrument, but, in order to…
Neutron Star Mergers Might not be the Only Source of r-Process Elements in the Milky Way
Benoit Côté, Marius Eichler, Almudena Arcones +8
Probing the origin of r-process elements in the universe represents a multi-disciplinary challenge. We review the observational evidence that probe the properties of r-process site…
r-Process Nucleosynthesis: Connecting Rare-Isotope Beam Facilities with the Cosmos
C. J. Horowitz, A. Arcones, B. Côté +35
This is an exciting time for the study of r-process nucleosynthesis. Recently, a neutron star merger GW170817 was observed in extraordinary detail with gravitational waves and elec…
Establishing the accuracy of asteroseismic mass and radius estimates of giant stars. I. Three eclipsing systems at [Fe/H]~ -0.3 and the need for a large high-precision sample
K. Brogaard, C. J. Hansen, A. Miglio +12
We aim to establish and improve the accuracy level of asteroseismic estimates of mass, radius, and age of giant stars. This can be achieved by measuring independent, accurate, and…
