英文摘要

We present optical spectroscopic and photometric observations of the nearby type Ic supernova (SN Ic) SN 2014L. This SN was discovered by the Tsinghua-NAOC Transient Survey (TNTS) in the nearby type-Sc spiral galaxy M99((NGC 4254). Fitting to the early-time light curve indicates that SN 2014L was detected at only a few hours after the shock breakout, and it reached a peak brightness of M-V = -17.73 +/- 0.28 mag (L = [2.06 +/- 0.50] x 10(42) erg s(-1)) approximately 13 days later. SN 2014L shows a close resemblance to SN 2007gr in the photometric evolution, while it shows stronger absorption features of intermediate-mass elements (especially Ca II) in the early-time spectra. Based on simple modeling of the observed light curves, we derived the mass of synthesized Ni-56 as M-Ni = 0.075 +/- 0.025 M-circle dot, and the mass and total energy of the ejecta as M-ej = 1.00 +/- 0.20 M-circle dot and E-ej = 1.45 +/- 0.25 foe, respectively. Given these typical explosion parameters, the early detection, and the extensive observations, we suggest that SN 2014L could be a template sample for the investigation of SNe Ic.
