Binarity and multiperiodicity in high-amplitude delta Scuti stars
A. Derekas, L. L. Kiss, T. R. Bedding +10
We have carried out a photometric and spectroscopic survey of bright high-amplitude delta Scuti (HADS) stars. The aim was to detect binarity and multiperiodicity (or both) in order…

Radial velocities of five globular clusters obtained with AAOmega
P. Székely, L. L. Kiss, K. Szatmáry +3
Using the recently commissioned multi-object spectrograph AAOmega on the 3.9m AAT we have obtained medium-resolution near-infrared spectra for 10,500 stars in and around five south…

A wide-field kinematic survey for tidal tails around five globular clusters
L. L. Kiss, P. Szekely, T. R. Bedding +2
Using the AAOmega instrument of the Anglo-Australian Telescope, we have obtained medium-resolution near-infrared spectra of 10,500 stars in two-degree fields centered on the galact…
