M101中SN 2011 fe的BVRI光度测定
BVRI Photometry of SN 2011fe in M101
摘要：
本文报道了M101中超新星2011 fe爆发后2.9 - 182天的BVRI测光结果。光变曲线和颜色演化表明SN 2011 fe属于Ia型超新星的“正常”子集，具有$Δm_{15}(B) = 1.21 \pm 0.03$等。在对消光进行修正并采用$(m - M) = 29.10$等到M101的距离模后，我们得到了绝对星等$M_B = -19.21$，$M_V = -19.19$，$M_R = -19.18$和$M_I = -18.94$。我们比较视觉测量的这一事件，我们的CCD测光，并找到证据的系统性差异的基础上的颜色。
英文摘要：
We present BVRI photometry of supernova 2011fe in M101 from 2.9 to 182 days after the explosion. The light curves and color evolution show that SN 2011fe belongs to the "normal" subset of type Ia supernovae, with $Δm_{15}(B) = 1.21 \pm 0.03$ mag. After correcting for extinction and adopting a distance modulus of $(m - M) = 29.10$ mag to M101, we derive absolute magnitudes $M_B = -19.21$, $M_V = -19.19$, $M_R = -19.18$ and $M_I = -18.94$. We compare visual measurements of this event to our CCD photometry and find evidence for a systematic difference based on color.
