  • Nebular phase observations of the type Ib supernova 2008D/X-ray transient 080109: side-viewed bipolar explosion 
    Tanaka, M; Yamanaka, M; Maeda, K; Kawabata, K. S; Hattori, T; Minezaki, T; Valenti, S; Valle, M. D; Sahu, D. K; Anupama, G. C; Tominaga, N; Nomoto, K; Mazzali, P. A; Pian, E (The American Astronomical Society, 2009-08)
    Abstract We present optical spectroscopic and photometric observations of supernova (SN) 2008D, associated with the luminous X-ray transient 080109, at >300 days after the explosion (nebular phases). We also give flux ...
  • On the observational behaviour of the highly polarized Type IIn supernova SN 2017hcc 
    Brajesh Kumar; Eswaraiah, C; Singh, A; Sahu, D. K; Anupama, G. C; Kawabata, K. S; Yamanaka, Masayuki; Otsubo, Ikki; Pandey, S. B; Nakaoka, Tatsuya; Kawabata, Miho; Aryan, Amar; Akitaya, Hiroshi (Oxford University Press on behalf of the Royal Astronomical Society, 2019-09)
    We present the results based on photometric (Swift UVOT), broad-band polarimetric (V and Rbands) and optical spectroscopic observations of the Type IIn supernova (SN) 2017hcc. Our study is supplemented with spectropolarimetric ...
  • The Peculiar Type Ib Supernova 2006jc: A WCO Wolf-Rayet Star Explosion 
    Tominaga, N; Limongi, M; Suzuki, T; Tanaka, M; Nomoto, K; Maeda, K; Chieffi, A; Tornambe, A; Minezaki, T; Yoshii, Y; Sakon, I; Wada, T; Ohyama, Y; Tanabé, T; Kaneda, H; Onaka, T; Nozawa, T; Kozasa, T; Kawabata, K. S; Anupama, G. C; Sahu, D. K; Gurugubelli, U. K; Prabhu, T. P; Deng, J (The American Astronomical Society, 2008-11)
    ISM: Dust, Extinction, Infrared: ISM, Nuclear Reactions, Nucleosynthesis, Abundances, Stars: Supernovae: General, supernovae: individual (SN 2006jc), Stars: Wolf-Rayet We present a theoretical model for Type Ib supernova ...
  • Properties of Newly Formed Dust Grains in the Luminous Type IIn Supernova 2010jl 
    Maeda, K; Nozawa, T; Sahu, D. K; Minowa, Y; Motohara, K; Ueno, I; Folatelli, G; Pyo, T. S; Kitagawa, Y; Kawabata, K. S; Anupama, G. C; Kozasa, T; Moriya, T. J; Yamanaka, M; Nomoto, K; Bersten, M; Quimby, R; Iye, M (IOP Publishing, 2013-10-10)
    Supernovae (SNe) have been proposed to be the main production sites of dust grains in the universe. However, our knowledge of their importance to dust production is limited by observationally poor constraints on the nature ...
  • Simultaneous MITSuME g'RCIC monitoring of S5 0716+714 
    Stalin, C. S; Kawabata, K. S; Uemura, M; Yoshida, M; Kawai, N; Yanagisawa, K; Shimizu, Y; Kuroda, D; Nagayama, S; Toda, H (Blackwell Publishing, 2009-11)
    We present the results of our intra-night optical flux monitoring observations of S5 0716+714 done simultaneously in g',RC and IC filters. The observations were done using the Multicolor Imaging Telescopes for Survey and ...
  • Type Ia Supernovae: Progenitors and Peculiarity 
    Nomoto, K; Tanaka, M; Kawabata, K. S; Sahu, D. K; Anupama, G. C (American Institute of Physics, 2007-08)
    Among the controversial issues on Type Ia supernovae (SNe Ia), we discuss (1) the evolutionary paths of the progenitor systems to SNe Ia, especially, the thermal stability of hydrogen shell burning in accreting white dwarfs, ...
