Spectroscopic Signatures of Extra-Tidal Stars Around the Globular Clusters NGC 6656 (M22), NGC 3201 and NGC 1851 from RAVE
Andrea Kunder, G. Bono, T. Piffl +22
Stellar population studies of globular clusters have suggested that the brightest clusters in the Galaxy might actually be the remnant nuclei of dwarf spheroidal galaxies. If the p…
The GALAH survey: Multiple stars and our Galaxy. I. A comprehensive method for deriving properties of FGK binary stars
G. Traven, S. Feltzing, T. Merle +24
Binary stellar systems form a large fraction of the Galaxy's stars. They are useful as laboratories for studying the physical processes taking place within stars, and must be corre…
The origin of the split red clump in the Galactic bulge of the Milky Way
M. Ness, K. Freeman, E. Athanassoula +8
Near the minor axis of the Galactic bulge, at latitudes b < -5 degrees, the red giant clump stars are split into two components along the line of sight. We investigate this split u…
Dissecting galactic bulges in space and time I: the importance of early formation scenarios vs. secular evolution
M. K. Seidel, R. Cacho, T. Ruiz-Lara +7
The details of bulge formation via collapse, mergers, secular processes or their interplay remain unresolved. To start answering this question and quantify the importance of distin…
Galaxy Genesis -- unravelling the epoch of dissipation in the early disk
J. Bland-Hawthorn, K. Freeman
So how did the Galactic disk form and can the sequence of events ever be unravelled from the vast stellar inventory? This will require that some of the residual inhomogeneities fro…
Looking for imprints of the first stellar generations in metal-poor bulge field stars
C. Siqueira-Mello, C. Chiappini, B. Barbuy +9
Context. Efforts to look for signatures of the first stars have concentrated on metal-poor halo objects. However, the low end of the bulge metallicity distribution has been shown t…
