" Supernovae Viewed from Various Angles: A power of Subaru and 8m-class telescopes "

Keiichi Maeda

(Kyoto University)

8m-class telescopes are important ingredients in follow-up observations of nearby supernovae (SNe), which can provide data with observing modes or at epochs which are difficult to obtain by smaller telescopes (near-infrared, high resolution, polarimetry, late phases). I will show some results we have obtained with the Subaru and other 8m-class telescopes about natures of supernovae. The topics will include discovery of dust formed in SNIIn 2010jl (in NIR by IRCS+AO188) and the detailed nature of these dust particles, discovery of oxygen-rich matter near the center of a peculiarly faint SN Ia 2010lp (in a late phase) which challenges to any existing theories, detailed follow-up observations of an enigmatic SN 2008ha-like SN Ia 2010ae (for which we find diversity within the class through the late-phase observations), and SN Ia 2008J having exploded within dense CSM (where the CSM properties are constrained through the high-resolution observations), and natures of SNe associated with Gamma-Ray Bursts. Aims and some preliminary results from ongoing Subaru observing programs will also be presented.

Seminars are also held at JAC, CFHT, and IfA.
