我们提出了我们对II型超新星DLT 16 am（SN 2016 ija）的分析。该天体是在正在进行的（DLT 40）为期一天的超新星搜索中发现的，位于附近的（）星系NGC 1532的“边缘”。随后的迅速和高节奏的光谱和光度跟踪显示了一个高度熄灭的瞬态，与RV = 3.1和明亮（）绝对峰值幅度的标准消光定律一致。与SNe II的大样本的光度特征的比较揭示了一个快速上升的派生光度和一个相对较短的平台阶段，与斜率，一致的光度特性的典型的快速下降的SNe II。尽管距离和消光的DLT 16上午的方向上有很大的不确定性，测量的光球膨胀速度和推导出的绝对V-波段的大小在爆炸后匹配现有的SNe II的光度速度关系。
We present our analysis of the Type II supernova DLT16am (SN 2016ija). The object was discovered during the ongoing (DLT40) one-day cadence supernova search at in the “edge-on” nearby ( ) galaxy NGC 1532. The subsequent prompt and high-cadenced spectroscopic and photometric follow-up revealed a highly extinguished transient, with , consistent with a standard extinction law with RV = 3.1 and a bright ( ) absolute peak magnitude. A comparison of the photometric features with those of large samples of SNe II reveals a fast rise for the derived luminosity and a relatively short plateau phase, with a slope of , consistent with the photometric properties typical of those of fast-declining SNe II. Despite the large uncertainties on the distance and the extinction in the direction of DLT16am, the measured photospheric expansion velocity and the derived absolute V-band magnitude at after the explosion match the existing luminosity–velocity relation for SNe II.
