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…
More pieces of the puzzle: Chemistry and substructures in the Galactic thick disk
Amina Helmi, Mary Williams, K. C. Freeman +2
We present a study of the chemical abundances of Solar neighbourhood stars associated to dynamical structures in the Milky Way's (thick) disk. These stars were identified as overde…
Galactic kinematics and dynamics from RAVE stars
James Binney, Ben Burnett, Georges Kordopatis +15
We analyse the kinematics of ~400000 RAVE stars. We split the sample into hot and cold dwarfs, red-clump and non-clump giants. The kinematics of the clump giants are consistent wit…
New distances to RAVE stars
James Binney, Ben Burnett, Georges Kordopatis +16
Probability density functions are determined from new stellar parameters for the distance moduli of stars for which the RAdial Velocity Experiment (RAVE) has obtained spectra with…
The wobbly Galaxy: kinematics north and south with RAVE red clump giants
M. E. K. Williams, M. Steinmetz, J. Binney +23
The RAVE survey, combined with proper motions and distance estimates, can be used to study in detail stellar kinematics in the extended solar neighbourhood (solar suburb). Using th…
Tracing the origin of the Aquarius Stream: I
Elizabeth Wylie-de Boer, Kenneth Freeman, Mary Williams +3
We present an abundance analysis of six member stars of the recently discovered Aquarius stream, in an attempt to ascertain whether this halo stream is real and, if so, to understa…
