摘要:

超新星在星系中的恒星和气体环境中的位置包含了寻找其祖先恒星的重要线索。作为利用哈勃太空望远镜(HST)成像数据研究超新星环境的计划的一部分,我们研究了NGC 4321(M100)中的II-L SN 1979 C的环境。我们对SN祖先的质量进行了更严格的限制,其质量可能为M \approx 17- 18 M_sun。此外,我们还恢复和测量了超新星1979 C在F439 W(~B; m_B(max)= 11.6)中的亮度,其亮度为23.37。.

英文摘要:

The locations of supernovae in the local stellar and gaseous environment in galaxies contain important clues to their progenitor stars. As part of a program to study the environments of supernovae using Hubble Space Telescope (HST) imaging data, we have examined the environment of the Type II-L SN 1979C in NGC 4321 (M100). We place more rigorous constraints on the mass of the SN progenitor, which may have had a mass M \approx 17--18 M_sun. Moreover, we have recovered and measured the brightness of SN 1979C, m=23.37 in F439W (~B; m_B(max) = 11.6), 17 years after explosion. .
