Properties of WNh stars in the Small Magellanic Cloud: evidence for homogeneous evolution
F. Martins, D. J. Hillier, J. C. Bouret +4
We derive the physical properties of three WNh stars in the SMC to constrain stellar evolution beyond the main sequence at low metallicity and to investigate the metallicity depend…
On the Importance of the Interclump Medium for Superionization: O VI Formation in the Wind of Zeta Pup
J. Zsargo, D. J. Hillier, J. -C. Bouret +3
We have studied superionization and X-ray line formation in the spectra of Zeta Pup using our new stellar atmosphere code (XCMFGEN) that can be used to simultaneously analyze optic…
Probing Shock Breakout with Serendipitous GALEX Detections of Two SNLS Type II-P Supernovae
Suvi Gezari, Luc Dessart, Stephane Basa +13
We report the serendipitous detection by GALEX of fast (<1 day) rising (>1 mag) UV emission from two Type II plateau (II-P) supernovae (SNe) at z=0.185 and 0.324 discovered by the…
SN 1994W: An Interacting Supernova or Two Interacting Shells?
Luc Dessart, D. John Hillier, Suvi Gezari +2
We present a multi-epoch quantitative spectroscopic analysis of the Type IIn SN 1994W, an event interpreted by Chugai et al. as stemming from the interaction between the ejecta of…
NLTE Model of NGC 6543's Central Star and its Relation with the Surrounding Planetary Nebula
L. N. Georgiev, M. Peimbert, D. J. Hillier +3
We analyze the chemical composition of the central star of the planetary nebula NGC 6543 based upon a detailed NLTE model of its stellar wind. The logarithmic abundances by number…
