英文摘要 | We have conducted photometric and spectroscopic observations of the peculiar Type Ia supernova (SN Ia) 2016ije that was discovered through the Tsinghua-NAOC Transient Survey. This peculiar object exploded in the outskirts of a metal-poor, low-surface brightness galaxy (i.e., M-g= 14.5 mag). Our photometric analysis reveals that SN 2016ije is subluminous (M-B,M-max = -17.65 +/- 0.06 mag) but exhibits relatively broad light curves (Delta m(15)(B)-1.35 +/- 0.14 mag), similar to the behavior of SN 2002es. Our analysis of the bolometric light curve indicates that only 0.14 +/- 0.04 M-circle dot of Ni-56 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, SN 2016ije resembles other SN 2002es-like SNeIa, except that the ejecta velocity inferred from its carbon absorption line (similar to 4500 km s(-1)) is much lower than that from silicon lines (similar to 8300 km s(-1)) at around the maximum light. Additionally, most of the absorption lines are broader than other 02es-like SNe Ia. These peculiarities suggest the presence of significant unburned carbon in the inner region and a wide line-forming region along the line of sight. These characteristics suggest that SN 2016ije might originate from the violent merger of a white dwarf binary system, when viewed near an orientation along the iron-group-element cavity caused by the companion star. |
