FIRE Classification of iPTF13bvn
Abstract
We observed iPTF13bvn (ATEL#5137) with the Folded-port InfraRed Echellette (FIRE; Simcoe et al. 2010) spectrograph on the Magellan Baade telescope on UT 2013 Jun 19.04. The spectrum covers 0.8 to 2.5um and shows prominent P Cygni profile of Helium I at 1.083 um at avelocity of 23000 km/s. We note that the 2um Helium I line is relatively weak. Confirming the tentative classification based on the optical spectrum (ATEL#5142), we conclude this is a supernova of Type Ib.
