Observational constraints on the origin of the elements. III. Evidence for the dominant role of sub-Chandrasekhar SN Ia in the chemical evolution of Mn and Fe in the Galaxy
Philipp Eitner, Maria Bergemann, Camilla Juul Hansen +4
The abundance ratios of manganese to iron in late-type stars across a wide metallicity range place tight constraints on the astrophysical production sites of Fe-group elements. In…
NLTE modelling of integrated light spectra. Abundances of barium, magnesium, and manganese in a metal-poor globular cluster
Philipp Eitner, Maria Bergemann, Soeren Larsen
We study the effects of non-local thermodynamic equilibrium (NLTE) on the abundance analysis of barium, magnesium, and manganese from integrated light spectroscopy, as typically ap…
Dynamics of the NGC 4636 globular cluster system II. Improved constraints from a large sample of globular cluster velocities
Ylva Schuberth, Tom Richtler, Michael Hilker +3
We present new radial velocities for 289 globular clusters around NGC 4636, the southernmost giant elliptical galaxy of the Virgo cluster. The data were obtained with FORS2/MXU at…
An optical/NIR survey of globular clusters in early-type galaxies II. Ages of GC systems and the relation to galaxy morphology
A. L. Chies-Santos, S. S. Larsen, H. Kuntschner +5
Context: Some photometric studies of extragalactic globular cluster (GC) systems using the optical and near-infrared colour combination have suggested the presence of a large fract…
Reddenings and metallicities in the LMC and SMC from Stroemgren CCD photometry
S. S. Larsen, J. V. Clausen, J. Storm
The individual reddenings for B stars in two fields in the Small Magellanic Cloud (SMC) and two fields in the Large Magellanic Cloud (LMC) are determined by means of Stroemgren uvb…
A new look at globular cluster colors in NGC 3311 and the case for exclusively metal-rich globular cluster systems
Jean P. Brodie, Soeren S. Larsen, Markus Kissler-Patig
NGC 3311, the central cD galaxy in the Hydra cluster, was previously thought to host the most metal-rich globular cluster system known. Ground-based Washington photometry had indic…
