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…
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…
ESC and KAIT Observations of the Transitional Type Ia SN 2004eo
A. Pastorello, P. A. Mazzali, G. Pignata +31
We present optical and infrared observations of the unusual Type Ia supernova (SN) 2004eo. The light curves and spectra closely resemble those of the prototypical SN 1992A, and the…
RR Lyrae stars in the southern globular cluster NGC 362
P. Szekely, L. L. Kiss, R. Jackson +3
NGC 362 is a bright southern globular cluster for which no extensive variability survey has ever been done. Time-series CCD photometric observations have been obtained. Light curve…
New clues on outburst mechanisms and improved spectroscopic elements of the black-hole binary V4641 Sagittarii
C. Lindstrom, J. Griffin, L. L. Kiss +4
We present spectroscopic observations of the black-hole binary V4641 Sagittarii, obtained between 4th July 2004 and 28th March 2005, which cover the minor outburst of the star in e…
The 2004--2006 outburst and environment of V1647 Ori
J. A. Acosta-Pulido, M. Kun, P. Abraham +15
(Abridged) We studied the brightness and spectral evolution of the young eruptive star V1647 Ori during its recent outburst in the period 2004 February - 2006 Sep. We performed a p…
