2013ApJ...772L..17T A Luminous and Fast-expanding Type Ib Supernova SN 2012au Takaki, Katsutoshi; Kawabata, Koji S.; Yamanaka, Masayuki; Maeda, Keiichi; Tanaka, Masaomi; Akitaya, Hiroshi; Fukazawa, Yasushi; Itoh, Ryosuke; Kinugasa, Kenzo; Moritani, Yuki; Ohsugi, Takashi; Sasada, Mahito; Uemura, Makoto; Ueno, Issei; Ui, Takahiro; Urano, Takeshi; Yoshida, Michitoshi; Nomoto, Ken'ichi Abstract. We present a set of photometric and spectroscopic observations of a bright Type Ib supernova SN 2012au from --6 days until ~ + 150 days after maximum. The shape of its early R-band light curve is similar to that of an average Type Ib/c supernova. The peak absolute magnitude is M_R_ = --18.7 +/- 0.2 mag, which suggests that this supernova belongs to a very luminous group among Type Ib supernovae. The line velocity of He I lambda5876 is about 15,000 km s^--1^ around maximum, which is much faster than that in a typical Type Ib supernova. From the quasi-bolometric peak luminosity of (6.7 +/- 1.3) x 10^42^ erg s^--1^, we estimate the ^56^Ni mass produced during the explosion as ~0.30 M_sun_. We also give a rough constraint to the ejecta mass 5-7 M_sun_ and the kinetic energy (7-18) x 10^51^ erg. We find a weak correlation between the peak absolute magnitude and He I velocity among Type Ib SNe. The similarities to SN 1998bw in the density structure inferred from the light-curve model as well as the large peak bolometric luminosity suggest that SN 2012au had properties similar to energetic Type Ic supernovae. Key words: supernovae: individual: SN 2012au
