Spectropolarimetry of the Unique Type Ib Supernova 2005bf: Larger Asymmetry Revealed by Later-Phase Data
Masaomi Tanaka, Koji S. Kawabata, Keiichi Maeda +6
We present an optical spectropolarimetric observation of the unique Type Ib supernova (SN) 2005bf at 8 days after the second maximum. The data, combined with the polarization spect…
The Extremely Luminous Supernova 2006gy at Late Phase: Detection of Optical Emission from Supernova
Koji S. Kawabata, Masaomi Tanaka, Keiichi Maeda +4
We performed optical spectroscopy and photometry of SN 2006gy at late time, ~400 days after the explosion, with the Subaru/FOCAS in a good seeing condition. We found that the SN fa…
SN 2006aj Associated with XRF 060218 At Late Phases: Nucleosynthesis-Signature of A Neutron Star-Driven Explosion
Keiichi Maeda, Koji Kawabata, Masaomi Tanaka +9
Optical spectroscopy and photometry of SN 2006aj have been performed with the Subaru telescope at t > 200 days after GRB060218, the X-ray Flash with which it was associated. Strong…
3D Models for High Velocity Features in Type Ia Supernovae
Masaomi Tanaka, Paolo A. Mazzali, Keiichi Maeda +1
Spectral synthesis in 3-dimensional (3D) space for the earliest spectra of Type Ia supernovae (SNe Ia) is presented. In particular, the high velocity absorption features that are c…
