BVRI photometry of the classic Type II-P supernova 2017eaw in NGC 6946: d 3 to d 594.


Abstract (from CDS):

Broadband BVRI light curves of SN 2017eaw in NGC 6946 reveal the classic elements of a Type II-P supernova. The observations were begun on 16 May 2017 (UT), approximately 1 d after the discovery was announced, and the photometric monitoring was carried out over a period of nearly 600 d. The light curves show a well-defined plateau and an exponential tail which curves slightly at later times. An approximation to the bolometric light curve is derived and used to estimate the amount of 56Ni created in the explosion; from various approaches described in the literature, we obtain M(56Ni) = 0.115–0.022+0.027M. We also estimate that 43 per cent of the bolometric flux emitted during the plateau phase is actually produced by the 56Ni chain. Other derived parameters support the idea that the progenitor was a red supergiant.
