SN 2005cs in M51 - II. Complete evolution in the optical and the near-infrared Export

TY - JOUR ID - citeulike:3889034 L3 - citeulike-article-id:3889034 N2 - We present the results of the one-year long observational campaign of the type II plateau SN 2005cs, which exploded in the nearby spiral galaxy M51 (the Whirlpool galaxy). This extensive data set makes SN 2005cs the best observed low-luminosity, <SUP>56</SUP>Ni-poor type II plateau event so far and one of the best core-collapse supernovae ever. The optical and near-infrared spectra show narrow P-Cygni lines characteristic of this SN family, which are indicative of a very low expansion velocity (about 1000kms<SUP>-1</SUP>) of the ejected material. The optical light curves cover both the plateau phase and the late-time radioactive tail, until about 380 d after core-collapse.
