Type Ia SN2016ije photometry and sp. follow-up

This peculiar object exploded in the outskirts of a metal-poor, low-surface brightness galaxy (i.e., M_g_=-14.5mag). Our photometric analysis reveals that SN 2016ije is subluminous (M_B,max_=-17.65+/-0.06mag) but exhibits relatively broad light curves ({Delta}m_15_(B)=1.35+/-0.14mag), similar to the behavior of SN 2002es.

Our analysis of the bolometric light curve indicates that only 0.14+/-0.04M_{sun}_ of ^56^Ni was synthesized in the explosion of SN 2016ije, which suggests a less energetic thermonuclear explosion when compared to normal SNe Ia, and this left a considerable amount of unburned materials in the ejecta. Spectroscopically, SN2016ije resembles other SN 2002es-like SNe Ia, except that the ejecta velocity inferred from its carbon absorption line (~4500km/s) is much lower than that from silicon lines (~8300km/s) at around the maximum light.
