Abstract:	超新星,是門古老的研究課題。在本論文中,我們使用鹿林一米望遠鏡(LOT)進行觀測,策略分為「發現」與「後續追蹤」兩大主題,以期對超新星的本質做更多了解。台灣超新星巡天計畫從2003年起進行,至今獨立發現通報了15顆超新星。而我選擇巨質量恆星演化到末期的Ib/c類型之超新星,進行後續光度變化的觀測:SN 2006jc,是人類見到恆星瀕臨死亡時,先噴出大量物質,兩年後旋即爆炸的事件,我們觀測到其在藍色波段較其他超新星下降緩慢。SN 2008D,與過往的超新星不同,是在X光波段率先發現,我們並在可見光波段觀測到超新星爆炸初期的資訊。未來,將繼續對Ib/c類型之超新星進行更深入的研究,投入泛星(Pan-STARRS)計畫,並使用多波段的觀測方式,來對超新星現象進行更全面的了解。 Supernova is an old research topic. In my thesis, we used Lulin one-meter telescope to observe. To understand the properties of supernovae, our observation strategy is divided into “discovery” and “follow-up”. Since 2003, Taiwan supernovae survey has discovered 15 new supernovae. I choose type Ib/c supernovae, which are the end stage of massive stars, to do follow-up observations. SN 2006jc had a big out-burst before its explosion. We observed its magnitude decay in B band is slower than other normal supernovae. SN 2008D is the first supernova detected by X-ray satellite. We have the earliest optical observations for supernova explosion. In future, I will keep on research type Ib/c supernovae, join the Pan-STARRS project, and use multi-wavelength observation to understand the nature of supernovae.
