Atomic Diffusion and Mixing in Old Stars VIII: Chemical abundance variations in the globular cluster M4 (NGC 6121)
T. Nordlander, P. Gruyters, O. Richard +1
Variations in chemical abundances with evolutionary phase have been identified among stars in globular and open clusters with a wide range of metallicities. In the metal-poor clust…
HRMOS White Paper: Science Motivation
Laura Magrini, Thomas Bensby, Anna Brucalassi +52
The High-Resolution Multi-Object Spectrograph (HRMOS) is a facility instrument that we plan to propose for the Very Large Telescope (VLT) of the European Southern Observatory (ESO)…
3D Stagger model atmospheres with FreeEOS I. Exploring the impact of microphysics on the Sun
Yixiao Zhou, Anish M. Amarsi, Victor Aguirre Børsen-Koch +3
Three-dimensional radiation-hydrodynamics (3D RHD) simulations of stellar surface convection provide valuable insights into many problems in solar and stellar physics. However, alm…
The SkyMapper search for extremely metal-poor stars in the Large Magellanic Cloud
W. S. Oh, T. Nordlander, G. S. Da Costa +2
We present results of a search for extremely metal-poor (EMP) stars in the Large Magellanic Cloud, which can provide crucial information about the properties of the first stars as…
Elemental Abundances of the Super-Neptune WASP-107b's Host Star Using High-resolution, Near-infrared Spectroscopy
Neda Hejazi, Ian Crossfield, Thomas Nordlander +8
We present the first elemental abundance measurements of the K dwarf (K7V) exoplanet-host star WASP-107 using high-resolution (R = 45,000), near-infrared (H- and K-band) spectra ta…
Raising the observed metallicity floor with a 3D non-LTE analysis of SDSS J102915.14+172927.9
C. Lagae, A. M. Amarsi, L. F. Rodríguez Díaz +4
Context: The first stars produced the first heavy elements and set the stage for the formation of the first galaxies. Accurate chemical abundances of ultra metal-poor stars ([Fe/H]…
