摘要

摘要我们介绍了利用 MSU 高加索山天文台的 2.5 米望远镜对超新星进行的测光和光谱观测。我们构建了2017egm、2017eaw、2018cow、2018aoq、2018zd、2019yvr、2019vxm、2020tlf和2020xtz天体的光变曲线，并确定了它们的基本参数。观测到的光变曲线与 SNe II-P 2017eaw 和 2018aoq 的理论计算结果进行了比较。展示了 SNe 2019vxm、2019yvr、2020tlf 和 2020xtz 的光谱。研究了 SNe IIn 2019vxm 和 2020tlf 的发射线剖面。对 SNe 2019yvr 和 2020xtz 进行了光谱建模。报告了 8 个天体的 SNe 光谱及时分类计划的结果。

Progress in Supernovae Studies with the 2.5-m Telescope at the Caucasus Mountain Observatory of SAI MSU

We present photometric and spectrocsopic observations of supernovae carried out with the 2.5-m telescope of the Caucasus Mountain Observatory of SAI MSU. The light curves for the objects 2017egm, 2017eaw, 2018cow, 2018aoq, 2018zd, 2019yvr, 2019vxm, 2020tlf, and 2020xtz were constructed and their basic parameters were determined. The observed light curves are compared to the theoretical calculations for SNe II-P 2017eaw and 2018aoq. The spectra of SNe 2019vxm, 2019yvr, 2020tlf, 2020xtz are presented. The profiles of emission lines are studied for SNe IIn 2019vxm and 2020tlf. Spectral modeling was carried out for SNe 2019yvr and 2020xtz. The results of the program of prompt SNe spectral classification for eight objects are reported.
