Circumstellar interaction of the type Ia supernova 2002ic
N. N. Chugai, R. A. Chevalier, P. Lundqvist
We propose a model to account for the bolometric light curve, quasi-continuum and the Ca II emission features of the peculiar type Ia supernova (SN) 2002ic, which exploded in a den…
Time-dependent thermal X-ray afterglows from GRBs
D. I. Kosenko, S. I. Blinnikov, K. A. Postnov +2
Time-dependent thermal X-ray spectra are calculated from physically plausible conditions around GRB. It is shown that account for time-dependent ionization processes strongly affec…
The origin of the high velocity circumstellar gas around SN 1998S
N. N. Chugai, S. I. Blinnikov, A. Fassia +3
Modelling of high resolution Balmer line profiles in the early-time spectra of SN 1998S shows that the inferred fast (roughly 400 km/s) circumstellar (CS) gas on days 23 and 42 pos…
Optical and Infrared Spectroscopy of the type IIn SN 1998S : Days 3-127
A. Fassia, W. P. S. Meikle, N. Chugai +14
We present contemporary infrared and optical spectroscopic observations of the type IIn SN 1998S for the period between 3 and 127 days after discovery. In the first week the spectr…
Circumstellar H-alpha from SN 1994D and future Type Ia supernovae: an observational test of progenitor models
R. J. Cumming, P. Lundqvist, L. J. Smith +2
Searching for the presence of circumstellar material is currently the only direct way to discriminate between the different types of possible progenitor systems for Type Ia superno…
