The Rich Are Different: Evidence from the RAVE Survey for Stellar Radial Migration
G. Kordopatis, J. Binney, G. Gilmore +21
Using the RAdial Velocity Experiment fourth data release (RAVE DR4), and a new metallicity calibration that will be also taken into account in the future RAVE DR5, we investigate t…
Characterizing the High-Velocity Stars of RAVE: The Discovery of a Metal-Rich Halo Star Born in the Galactic Disk
K. Hawkins, G. Kordopatis, G. Gilmore +21
We aim to characterize high-velocity (HiVel) stars in the solar vicinity both chemically and kinematically using the fourth data release of the RAdial Velocity Experiment (RAVE). W…
RAVE: Results and Updates from Data Release 4
G. Kordopatis
The RAdial Velocity Experiment (RAVE) published in November 2013 its fourth data release with the stellar atmospheric parameters, abundances, distances, radial velocities, proper m…
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…
APASS Landolt-Sloan BVgri photometry of RAVE stars. I. Data, effective temperatures and reddenings
U. Munari, A. Henden, A. Frigo +24
We provide APASS photometry in the Landolt BV and Sloan g'r'i' bands for all the 425,743 stars included in the latest 4th RAVE Data Release. The internal accuracy of the APASS phot…
Pseudo Three-dimensional Maps of the Diffuse Interstellar Band at 862 nm
Janez Kos, Tomaž Zwitter, Rosemary Wyse +20
The diffuse interstellar bands (DIBs) are absorption lines observed in visual and near infrared spectra of stars. Understanding their origin in the interstellar medium (ISM) is one…
Chemical gradients in the Milky Way from the RAVE data. II. Giant stars
C. Boeche, A. Siebert, T. Piffl +19
We provide new constraints on the chemo-dynamical models of the Milky Way by measuring the radial and vertical chemical gradients for the elements Mg, Al, Si, Ti, and Fe in the Gal…
Weighing the local dark matter with RAVE red clump stars
O. Bienaymé, B. Famaey, A. Siebert +16
We determine the Galactic potential in the solar neigbourhood from RAVE observations. We select red clump stars for which accurate distances, radial velocities, and metallicities h…
Constraining the Galaxy's dark halo with RAVE stars
T. Piffl, J. Binney, P. J. McMillan +17
We use the kinematics of giant stars that lie within kpc of the plane to measure the vertical profile of mass density near the Sun. We find that the dark…
Kinematic modelling of the Milky Way using the RAVE and GCS stellar surveys
S. Sharma, J. Bland-Hawthorn, J. Binney +19
We investigate the kinematic parameters of the Milky Way disc using the RAVE and GCS stellar surveys. We do this by fitting a kinematic model to the data taking the selection funct…
The Gaia-ESO Survey: radial metallicity gradients and age-metallicity relation of stars in the Milky Way disk
M. Bergemann, G. Ruchti, A. Serenelli +42
We study the relationship between age, metallicity, and alpha-enhancement of FGK stars in the Galactic disk. The results are based upon the analysis of high-resolution UVES spectra…
