The Dawning of the Stream of Aquarius in RAVE
Mary E. K. Williams, Matthias Steinmetz, Sanjib Sharma +22
We identify a new, nearby (0.5 < d < 10 kpc) stream in data from the RAdial Velocity Experiment (RAVE). As the majority of stars in the stream lie in the constellation of Aquarius…
Detection of a radial velocity gradient in the extended local disc with RAVE
A. Siebert, B. Famaey, I. Minchev +22
Using a sample of 213,713 stars from the Radial Velocity Experiment (RAVE) survey, limited to a distance of 2 kpc from the Sun and to |z|<1 kpc, we report the detection of a veloci…
Local Stellar Kinematics from RAVE Data: I. Local Standard of Rest
B. Coskunoglu, S. Ak, S. Bilir +19
We analyze a sample of 82850 stars from the RAVE survey, with well-determined velocities and stellar parameters, to isolate a sample of 18026 high-probability thin-disc dwarfs with…
Testing formation mechanisms of the Milky Way's thick disc with RAVE
Michelle Wilson, Amina Helmi, H. L. Morrison +21
We study the eccentricity distribution of a thick disc sample of stars observed in the Radial Velocity Experiment (RAVE) and compare it to that expected in four simulations of thic…
Origins of the Thick Disk as Traced by the Alpha-Elements of Metal-Poor Giant Stars Selected from RAVE
G. R. Ruchti, J. P. Fulbright, R. F. G. Wyse +20
Theories of thick disk formation can be differentiated by measurements of stellar elemental abundances. We have undertaken a study of metal-poor stars selected from the RAVE spectr…
Halo globular clusters observed with AAOmega: dark matter content, metallicity and tidal heating
Richard R. Lane, László L. Kiss, Geraint F. Lewis +6
Globular clusters have proven to be essential to our understanding of many important astrophysical phenomena. Here we analyse spectroscopic observations of ten Halo globular cluste…
