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…
An abundance study of red-giant-branch stars in the Hercules dwarf spheroidal galaxy
D. Adén, K. Eriksson, S. Feltzing +3
Using high-resolution spectroscopy, we provide a determination of [Fe/H] and [Ca/H] for confirmed red-giant branch member stars of the Hercules dwarf spheroidal galaxy. Based on th…
The RAVE Survey: Rich in Very Metal-Poor Stars
Jon P. Fulbright, Rosemary F. G. Wyse, Gregory R. Ruchti +20
Very metal-poor stars are of obvious importance for many problems in chemical evolution, star formation, and galaxy evolution. Finding complete samples of such stars which are also…
Dwarf galaxies beyond our doorstep: the Centaurus A group
D. Crnojević, E. K. Grebel, A. A. Cole +4
The study of dwarf galaxies in groups is a powerful tool for investigating galaxy evolution, chemical enrichment and environmental effects on these objects. Here we present results…
