摘要:	羅賽塔任務從 2014 年八月底達彗星後，在約一年半的時間中陸續傳回許多寶貴的資料，其中包含菲萊登陸器在彗星上60 小時的獨一無二的彗核表面的資料，ESA 這項任務預計在2016 年九月結束，但其所觀測的資料卻可讓參與的團隊持續研究好幾個月甚至數十年；我與台灣團隊也將持續與羅賽塔任務參與人員合作繼續研究這＂古老又嶄新的彗星科學＂。除此之外，我們知道彗星的太空任務是可遇而不可求的，因此地面的彗星觀測更顯得重要!尤其是在羅賽塔任務後再度為這古老的彗星研究又遇新的瓶頸，此計畫我將結合地面的觀測與羅賽塔任務觀測資料，尋找內、外部彗髮觀測資料的相連性並尋求新的彗星模型來解釋這難得機會；另外我也將接聯合並申請可用的地面觀測資源(台灣部分LOT, JCMT, SMA, and CFHT)與合作夥伴中國、德國、西班牙與美國等(Lijiang, Xinglong, Calar Alto observatories, and TianMa, UH, VLT telescopes)組成日不落的彗星觀測，我已經參與彗星艾桑(C/2012 S1 (ISON))與67P/C‐G 的研究，未來將持續參與並主導彗星”4XP”與其它新彗星聯合觀測並導入羅賽塔任務的研究結果，讓這＂後羅賽塔任務的彗星研究＂邁入新一面。 ;Rosetta spacecraft has already followed the comet 67P/Churyumov‐Gerasimenko for one and half years. Now the comet C‐G is on its way back out into deep space and then ESA will terminate Rosetta mission in the end of September 2016. Since Rosetta arrived to comet C‐G in August 2014, Rosetta has been sending a lot of data back to Earth. Fortunately, we have data access of the onboard instrument, OSIRIS, and we therefore can publish some fresh results in 2015/2016. Results from the Rosetta mission to comet C‐G are leading to a revolution in our understanding of these ancient bodies, and hence the conditions prevalent in the early Solar System. For the coming years, I will continuous use the OSIRIS data set for investigating this relatively new cometary science. In addition to the data from ROSETTA mission, the ground‐based observations to the other comets are important because they are easy to arrange and cost a few money compared to space mission. The resulted data observed in the same ways from Earth can make a direct comparison between 67P and other Jupiter family comets and even the dynamically new comets. For building the comprehensive data, we plan to use all the available facilities (LOT, JCMT, SMA, and CFHT) we have in Taiwan site and cooperate to people who are in China, Germany, Spain and US (Lijiang, Xinglong, Calar Alto observatories, and TianMa, UH, VLT telescopes). Comet ISON and comet C‐G have been organized successfully in 2013 and 2014‐16, respectively. The new campaign named “Comets 4*P Campaign” from 2017 to 2019 will be focus on the short period comets (i.e. 45P, 41P and 46P). The basic structure and goals of the campaign will be similar to that for comet ISON and comet C‐G on organizing a coma morphology study by means of the better longitudinal coverage during the world.
