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…
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…
On the identification of merger debris in the {\it Gaia} Era
Facundo A. Gómez, Amina Helmi, Anthony G. A. Brown +1
We model the formation of the Galactic stellar halo via the accretion of satellite galaxies onto a time-dependent semi-cosmological galactic potential. Our goal is to characterize…
Distance determination for RAVE stars using stellar models
M. A. Breddels, M. C. Smith, A. Helmi +21
(Abridged) Aims:We develop a method for deriving distances from spectroscopic data and obtaining full 6D phase-space coordinates for the RAVE survey's second data release. Methods:…
