Fe XIII emission lines in active region spectra obtained with the Solar Extreme-Ultraviolet Research Telescope and Spectrograph
F P Keenan, D B Jess, K M Aggarwal +3
Recent fully relativistic calculations of radiative rates and electron impact excitation cross sections for Fe {\sc xiii} are used to generate emission-line ratios involving 3s$^{2…
The Peculiar Type Ia Supernova 2005hk
V. Stanishev, S. Taubenberger, G. Blanc +15
We present a preliminary analysis of an extensive set of optical observations of the Type Ia SN 2005hk. We show that the evolution of SN 2005hk closely follows that of the peculiar…
Proof of polar ejection fom the close-binary core of the planetary nebula Abell 63
Deborah L. Mitchell, Don Pollacco, T. J. O'Brien +4
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…
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…
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…
