The nature of SN 1997D: low-mass progenitor and weak explosion (2007)
Nikolai Chugai And, Nikolai N. Chugai, Victor P. Utrobin
. We analyzed the spectra and light curve of the peculiar type II-P supernova 1997D to recover ejecta parameters. The optimal hydrodynamical model of SN 1997D, which meets observational constraints...
Optical Signatures of Circumstellar Interaction in Type IIP Supernovae (2007)
Chugai, Nikolai N., Chevalier, Roger A., Utrobin, Victor P.
We propose new diagnostics for circumstellar interaction in Type IIP supernovae by the detection of high velocity (HV) absorption features in Halpha and He I 10830 A lines during the photospheric...
The nature of SN 1997D: low-mass progenitor and weak explosion (1999)
Chugai, Nikolai N., Utrobin, Victor P.
We analyzed the spectra and light curve of the peculiar type II-P supernova 1997D to recover ejecta parameters. The optimal hydrodynamical model of SN 1997D, which meets observational constraints at...
