We present the first detailed kinematical analysis of the planetary nebula Abell 63, which is known to contain the eclipsing close-binary nucleus UU Sge. Abell 63 provides an impor…
The circumstellar environment of rotating Wolf-Rayet Stars and the implications for GRB afterglows
J. J. Eldridge
If Wolf-Rayet stars are the progenitors of Gamma-ray bursts (GRBs), they must rotate rapidly to produce the GRB. This rotation may effect their stellar-wind bubbles and possibly ex…

We present results based on Spitzer Space Telescope mid-infrared (3.6-30 micron) observations of the nearby IIP supernova 2005af. We report the first ever detection of the SiO mole…
A fast hybrid algorithm for exoplanetary transit searches
A. Collier Cameron, D. Pollacco, R. A. Street +22
We present a fast and efficient hybrid algorithm for selecting exoplanetary candidates from wide-field transit surveys. Our method is based on the widely-used SysRem and Box Least-…
The Type Ia supernova 2004S, a clone of SN 2001el, and the optimal photometric bands for extinction estimation
Kevin Krisciunas, Peter M. Garnavich, Vallery Stanishev +9
We present optical (UBVRI) and near-infrared (YJHK) photometry of the normal Type Ia supernova 2004S. We also present eight optical spectra and one near-IR spectrum of SN 2004S. Th…
The VLT-FLAMES survey of massive stars: Surface chemical compositions of B-type stars in the Magellanic Clouds
I. Hunter, P. L. Dufton, S. J. Smartt +6
We present an analysis of high-resolution FLAMES spectra of approximately 50 early B-type stars in three young clusters at different metallicities, NGC6611 in the Galaxy, N11 in th…
WASP-1b and WASP-2b: Two new transiting exoplanets detected with SuperWASP and SOPHIE
A. Collier Cameron, F. Bouchy, G. Hebrard +36
We have detected low-amplitude radial-velocity variations in two stars, USNO-B1.0 1219-0005465 (GSC 02265-00107 = WASP-1) and USNO-B1.0 0964-0543604 (GSC 00522-01199 = WASP-2). Bot…

A. M. S. Smith, A. Collier Cameron, D. J. Christian +19
We present a model of the stellar populations in the fields observed by one of the SuperWASP-N cameras in the 2004 observing season. We use the Besancon Galactic model to define th…
