摘要:

我们介绍了2017年5月14日至12月7日期间在NGC 6946中获得的超新星2017eaw的UBVRI测光。我们推导出了UVVRI波段最大光的日期和量级以及光变曲线的参数。讨论了SN 2017的颜色演化、消光和最大亮度。进行了初步的模拟,结果与UBVRI波段的光变曲线符合得令人满意。

英文摘要:

We present UBVRI photometry of the supernova 2017eaw in NGC 6946, obtained in the period from May 14 until December 7, 2017. We derive dates and magnitudes of maximum light in the UBVRI bands and the parameters of the light curves. We discuss colour evolution, extinction and maximum luminosity of SN 2017eaw. Preliminary modeling is carried out, and the results are in satisfactory agreement with the light curves in the UBVRI bands.
