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…
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…
On the Search For Transits of the Planets Orbiting Gl 876
P. D. Shankland, E. J. Rivera, G. Laughlin +14
We report the results of a globally coordinated photometric campaign to search for transits by the P ~ 30 d and P ~ 60 d outer planets of the 3-planet system orbiting the nearby M-…
The Anomalous Early Afterglow of GRB 050801
E. S. Rykoff, V. Mangano, S. A. Yost +24
The ROTSE-IIIc telescope at the H.E.S.S. site, Namibia, obtained the earliest detection of optical emission from a Gamma-Ray Burst (GRB), beginning only 21.8 s from the onset of Sw…
Optical Lightcurve & Cooling Break of GRB 050502A
S. A. Yost, K. Alatalo, E. S. Rykoff +29
We present lightcurves of the afterglow of GRB050502A, including very early data at t-t_{GRB} < 60s. The lightcurve is composed of unfiltered ROTSE-IIIb optical observations from 4…
Binarity and multiperiodicity in high-amplitude delta Scuti stars
A. Derekas, L. L. Kiss, B. Csak +6
We present our first results for a sample of southern high-amplitude delta Scuti stars (HADS), based on a spectrophotometric survey started in 2003. For CY Aqr and AD CMi, we found…
