Granulation across the HR diagram
I. Ramirez, C. Allende Prieto, D. L. Lambert +2
We have obtained ultra-high quality spectra (R=180,000; S/N>300) with unprecedented wavelength coverage (4400 to 7400 A) for a number of stars covering most of the HR diagram in or…
O and Na abundance patterns in open clusters of the Galactic disk
G. M. De Silva, B. K. Gibson, J. Lattanzio +1
Aims. A global O-Na abundance anti-correlation is observed in globular clusters, which is not present in the Galactic field population. Open clusters are thought to be chemically h…
Chemical similarities between Galactic bulge and local thick disk red giant stars
J. Melendez, M. Asplund, A. Alves-Brito +8
The evolution of the Milky Way bulge and its relationship with the other Galactic populations is still poorly understood. The bulge has been suggested to be either a merger-driven…
Signatures of Granulation in the Spectra of K-Dwarfs
I. Ramirez, C. Allende Prieto, D. L. Lambert +1
Very high resolution (R>150,000) spectra of a small sample of nearby K-dwarfs have been acquired to measure the line asymmetries and central wavelength shifts caused by convective…
Beyond 1D: spectral line formation with 3D hydrodynamical model atmospheres of red giants
R. Collet, M. Asplund, R. Trampedach
We present the results of realistic, 3D, hydrodynamical, simulations of surface convection in red giant stars with varying effective temperatures and metallicities. We use the conv…
Chemically Tagging the HR1614 Moving Group
G. M. De Silva, K. C. Freeman, J. Bland-Hawthorn +2
We present abundances for a sample of F,G,K dwarfs of the HR1614 moving group based on high resolution, high S/N ratio spectra from AAT/UCLES. Our sample includes stars from Feltzi…
