Type Ia Supernova Spectral Line Ratios as Luminosity Indicators
Sebastien Bongard, E. Baron, G. Smadja +2
Type Ia supernovae have played a crucial role in the discovery of the dark energy, via the measurement of their light curves and the determination of the peak brightness via fittin…
Hydrogen and helium traces in type Ib-c supernovae
A. Elmhamdi, I. J. Danziger, D. Branch +3
The spectroscopic properties of a selected optical photospheric spectra of core collapse supernovae (CCSNe) are investigated.Special attention is devoted to traces of hydrogen at e…
Quantitative Spectroscopy of Supernovae for Dark Energy Studies
E. Baron, David Branch, David Jeffery +6
Detailed quantitative spectroscopy of Type Ia supernovae (SNe~Ia) provides crucial information needed to minimize systematic effects in both ongoing SNe Ia observational programs s…
SN 1998A: Explosion of a Blue Supergiant
A. Pastorello, E. Baron, D. Branch +11
We present spectroscopic and photometric observations of the peculiar Type II supernova (SN) 1998A. The light curves and spectra closely resemble those of SN 1987A, suggesting that…
Comparative Direct Analysis of Spectra of Type Ia Supernovae. I. SN 1994D
David Branch, E. Baron, Nicholas Hall +2
As the first step in a comprehensive, comparative, direct analysis of the spectra of Type Ia supernovae (SNe Ia), we use the parameterized supernova synthetic-spectrum code, SYNOW,…
Effects of Gravitational Microlensing on P-Cygni Profiles of Type Ia Supernovae
Hamed Bagherpour, David Branch, R. Kantowski
A brief description of the deformed spectra of microlensed SNe Ia is presented. We show that microlensing amplification can have significant effects on line profiles. The resonance…
