摘要:

我们回顾了最近的紫外线观测的核心坍缩超新星(SNe)与雨燕紫外/光学望远镜(UVOT)在其头两年。静止帧紫外光度法是有用的区分SN类型,利用紫外光谱形状和更微妙的紫外功能。这对于仅使用测光的局部和高红移SNe的实时分类是有用的。用UVOT观测到两个显著的超新星Ib/c,其中SN 2006 jc是一个紫外亮的超新星Ib。对GRB 060218/SN 2006 aj的快速观测在爆炸后不久开始,并显示出一个紫外明亮的峰值,随后是紫外微弱的SN凸起。紫外观测也是有用的约束温度和电离结构的SNe IIP。所有类型的静止帧UV观测对于理解SNe的消光、温度和热光度以及解释在光学波长处观测到的高红移SNe的观测都是重要的。

英文摘要:

We review recent UV observations of core-collapse supernovae (SNe) with the Swift Ultra-violet/Optical Telescope (UVOT) during its first two years. Rest-frame UV photometry is useful for differentiating SN types by exploiting the UV-optical spectral shape and more subtle UV features. This is useful for the real-time classification of local and high-redshift SNe using only photometry. Two remarkable SNe Ib/c were observed with UVOT -- SN2006jc was a UV bright SN Ib. Swift observations of GRB060218/SN2006aj began shortly after the explosion and show a UV-bright peak followed by a UV-faint SN bump. UV observations are also useful for constraining the temperature and ionization structure of SNe IIP. Rest-frame UV observations of all types are important for understanding the extinction, temperature, and bolometric luminosity of SNe and to interpret the observations of high redshift SNe observed at optical wavelengths.
