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…

Broad emission lines from opaque electron-scattering environment of SN 1998S
N. N. Chugai
I propose that broad narrow-topped emission lines with full width at zero intensity >20000 km/s, seen in early-time spectra of SN 1998S, originate from a dense circumstellar gas an…
