Spectrophotometry of type Ib/c SN 1997X: HeI lines near maximum light.
MUNARI U., BARBON R., PIEMONTE A., TOMASELLA L. and REJKUBA M.
Abstract (from CDS):
Low resolution B&C+CCD (range 3600Å-1.0µm) and high resolution Echelle+CCD (range 5800-8100Å) spectrophotometry of type Ib/c SN 1997X near maximum light is presented and discussed. The supernova is notheworthy in having presented absorption lines of He I at early phases (at an expansion velocity of 11000km/s). From the interstellar NaI D lines a reddening of EB–V=0.18±0.02mag has been derived, which arises in the host galaxy. From the emission lines of the underlying H II region, a density of Ne≤100 and a velocity of RV☉=1098±3km/s are obtained.
