A Wide Metallicity Range for Gyr-old Stars in the Nuclear Star Cluster
Brian Thorsbro, Rebecca Forsberg, Georges Kordopatis +6
We report metallicities for three Gyr-old stars in the Milky Way nuclear star cluster (NSC) using high-resolution near-infrared spectroscopy. We derive effective temperatures…
M Giants with IGRINS III. Abundance Trends for 21 Elements in the Solar Neighborhood from High-Resolution, Near-Infrared Spectra
G. Nandakumar, N. Ryde, R. Forsberg +4
In order to investigate the chemical history of the entire MilkyWay, it is imperative to also study the dust-obscured regions, where most of the mass lies. The Galactic Center is a…
The Mantis Network III: Expanding the limits of chemical searches within ultra hot-Jupiters. New detections of Ca I, V I, Ti I, Cr I, Ni I, Sr II, Ba II, and Tb II in KELT-9 b
N. W. Borsato, H. J. Hoeijmakers, B. Prinoth +5
Cross-correlation spectroscopy is an invaluable tool in the study of exoplanets. However, aliasing between spectral lines makes it vulnerable to systematic biases. This work strive…
The first r-process enhanced star confirmed to be a member of the Galactic bulge
R. Forsberg, R. M. Rich, N. Nieuwmunster +4
Aims. Stars with strong enhancements of r-process elements are rare and tend to be metal-poor, with generally [Fe/H] <-2 dex and found in the halo. In this work we aim to investiga…
Abundances of disk and bulge giants from high-resolution optical spectra V. Molybdenum -- the p-process element
Rebecca Forsberg, Nils Ryde, Henrik Jönsson +2
Aims. In this work, we aim to make a differential comparison of the neutron-capture and p-process element molybdenum (Mo) in the stellar populations in the local disk(s) and the bu…
Chemical Evolution of Ytterbium in the Galactic Disk
M. Montelius, R. Forsberg, N. Ryde +8
Measuring the abundances of neutron-capture elements in Galactic disk stars is an important part of understanding key stellar and galactic processes. In the optical wavelength regi…
Fluorine in the solar neighbourhood: the need for several cosmic sources
Nils Ryde, Henrik Jönsson, Gregory Mace +14
The cosmic origin of fluorine is still not well constrained. Several nucleosynthetic channels at different phases of stellar evolution have been suggested, but these must be constr…
Modelling the chemical evolution of Zr, La, Ce and Eu in the Galactic discs and bulge
V. Grisoni, G. Cescutti, F. Matteucci +3
We study the chemical evolution of Zr, La, Ce and Eu in the Milky Way discs and bulge by means of chemical evolution models compared with recent spectroscopic data. We consider det…
Abundances of disk and bulge giants from high-resolution optical spectra -- IV. Zr, La, Ce, Eu
Rebecca Forsberg, Henrik Jönsson, Nils Ryde +1
Stellar mass and metallicity are factors that affect the neutron-capture process. Due to this, the enrichment of the ISM and the abundance of neutron-capture elements vary with tim…
Stellar abundance of binary stars: their role in determining the formation location of super-Earths and ice giants
Bertram Bitsch, Rebecca Forsberg, Fan Liu +1
Binary stars form from the same parent molecular cloud and thus have the same chemical composition. Forming planets take building material (solids) away from the surrounding protop…
