论文摘要
为IC-BL Supernovae 2016COI和2018EBT提供了CCD BVRI光度法。这两个对象的光曲线的形状对于此类SNE都是典型的。 SN 2016COI最大光后约100天，亮度下降率的变化变化。 SN 2018EBT的光曲线最好与SN IC-BL 2002AP的光曲线相匹配。对于SN 2018EBT，我们得出了最大光的日期和幅度，进化后期下降速率以及在宿主星系中灭绝的证据忽略不计。
CCD BVRI photometry is presented for the type Ic-BL Supernovae 2016coi and 2018ebt. The shape of the light curves for both objects is typical for this class of SNe. A change of brightness decline rate at about 100 days after maximum light is observed for SN 2016coi. The light curves of SN 2018ebt are best matched by those of SN Ic-BL 2002ap. For SN 2018ebt, we derived the dates and magnitudes of maximum light, rates of decline at late stages of evolution and presented evidence for extinction in the host galaxy being negligible.
