超新星是宇宙中能量等級最高之一的天文現象，爆發時的最大亮度幾乎等於一整個星系放出的光，但是由於是偶發性的天文現象而且視星等大都是12等以上，所以早年對超新星的研究並不多。近十年來，光學觀測儀器及電腦的進步，讓超新星的發現數量有了大幅度的成長，這也開啟了超新星的研究。由於是偶發性的天文現象，所以需要及時和越多數量的超新星以供研究。現今世界上的超新星巡天團隊大部份都是位處於北半球，這使得大部份發現的超新星都是集中在天球赤道以北。台灣位處於北緯23度，在觀測上有南天可見星場可達-40°的優勢，在北京天文台裘雨雷老師的技術指導下，台灣超新星尋天利用中央大學鹿林天文台一米望遠鏡(Lulin One-meter Telescope, LOT)做尋天的觀測，所選的1573目標均為鄰近星系，主要分布在DEC:0°~DEC:-40°之間。為了讓觀測更有效率，在觀測時不使用濾鏡，設定曝光時間為15秒以增加巡天效率。在觀測週期上，大約每十天觀測可見星系一次，依照觀測設定，平均一分鐘可以觀測1.6個目標，最多一晚可觀測1000多個星系、橫跨16個赤緯。經過二年多的巡天觀測後，台灣超新星巡總共獨立發現了11顆超新星、1顆Mira變星。另外也對超新星與所在星系做了一系列的分析，並且對一顆超新星做了後續光變觀測。 Supernova is one of highest energy phenomenon in the universe. The maximum brightness of supernova almost equals all brightness of one galaxy when it explodes. Due to fortuitous phenomenon and the magnitude is larger than twelve, there are not very many researches in supernova in early years. In decade recently, the development of optical instrument and computer make the amount of discovered supernovae and researches increase. For the incidental, the research of supernova needs many timely supernovae. The teams of supernova survey in whole world almost be located at the northern hemisphere. It makes the discovered supernovae are concentrated in Dec.>0. Taiwan is located at N23°, the field of view can reach Dec=-40°. Under Prof. Yu-lei Qiu's (Beijing Astronomical Observatory) help, Taiwan Supernovae Survey (TSS) use Lulin One-meter Telescope (LOT) of NCU for observation. The 1573 target galaxies are located at Dec:0°~Ded:-40°. For efficient observation, unfilter and 15 second exposure time used. The every run of observation is about ten days, 1.6 targets can be observed in one minute. Containing 16 R.A., more than one thousand galaxies can be observed in one night. After two and a half years, TSS found eleven supernovae and one Mira variable star independently. Besides, the analysis of supernova with host galaxy and follow-up was done.
