0.056

Narrow emission features (FWHM ~ 40-60 Angstrom) dominate the blue continuum, with HeII 4686 being the strongest. Redshift is estimated using He II and Hydrogen Balmer features.

STARGATE

SN II

0.056

STARGATE

The spectrum is dominated by emission lines, that can be interpreted as strong He II 4686 (with a blue shoulder possibly associated with NIII / CIII) together with H-alpha and H-beta on top of a blue continuum, at a common redshift z = 0.056. A comparison with SNID (Blondin & Tonry 2007, ApJ, 666, 1024) shows that the best matching template is that of SN 1998S at 12 days before maximum.
