Double-lined Spectroscopic Binary Stars in the Radial Velocity Experiment Survey
G. Matijevic, T. Zwitter, U. Munari +19
We devise a new method for the detection of double-lined binary stars in a sample of the Radial Velocity Experiment (RAVE) survey spectra. The method is both tested against extensi…
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…
AAOmega Observations of 47 Tucanae: Evidence for a Past Merger?
Richard R. Lane, Brendon J. Brewer, László L. Kiss +6
The globular cluster 47 Tucanae is well studied but it has many characteristics that are unexplained, including a significant rise in the velocity dispersion profile at large radii…
