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…
AAOmega radial velocities rule out current membership of the planetary nebula NGC 2438 in the open cluster M46
L. L. Kiss, Gy. M. Szabo, Z. Balog +2
We present new radial velocity measurements of 586 stars in a one-degree field centered on the open cluster M46, and the planetary nebula NGC 2438 located within a nuclear radius o…
The University of New South Wales Extrasolar Planet Search: a catalogue of variable stars from fields observed 2004--2007
J. L. Christiansen, A. Derekas, L. L. Kiss +7
We present a new catalogue of variable stars compiled from data taken for the University of New South Wales Extrasolar Planet Search. From 2004 October to 2007 May, 25 target field…
High and low states of the system AM Herculis
K. Wu, L. L. Kiss
Context: We investigate the distribution of optically high and low states of the system AM Herculis (AM Her). Aims: We determine the state duty cycles, and their relationships with…
