Mass Constraints for the Progenitor of the Core Collapse Supernova

我们利用光学IFU、窄带成像等观测手段研究了附近超新星的爆炸地点，并利用UH88英寸望远镜上的SNIFS数据和Gemini-N望远镜上的GMOS数据，对核塌缩超新星的质量和金属丰度进行了约束研究。我们还研制了一种新的仪器LISS(Line Imager And Sit Spectrgraph)，它可以用法布里-珀罗标准具进行窄带成像。

We carried out studies to constrain the progenitor mass of the core collapse supernovae by studying the explosion site of nearby supernovae with optical IFU, narrow-band imaging, and other observations.We published two papers in which we constrain mass and metalicity of the nearby core collapse supernovae using the data taken with SNIFS on UH88inch telescope and with GMOS on GEMINI-N telescope. We also develop a new instrument LISS (Line Imager and Slit Spectrograph) with which we can carry out narrow-band imaging with a Fabry-Perot etalon.
