  • 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 ...
  • Optical photometry and spectroscopy of the Type Ibn supernova SN 2006jc until the onset of dust formation 
    Anupama, G. C; Sahu, D. K; Gurugubelli, U. K; Prabhu, T. P; Tominaga, N; Tanaka, M; Nomoto, K (Royal Astronomical Society, 2009-01)
    We present optical UBVRI photometric and spectroscopic data of the Type Ibn supernova SN 2006jc, until the onset of the dust-forming phase. The optical spectrum shows a blue continuum and is dominated by the presence of ...
  • Optical studies of SN 2009jf: a Type Ib supernova with an extremely slow decline and aspherical signature 
    Sahu, D. K; Gurugubelli, U. K; Anupama, G. C; Nomoto, K (Wiley-Blackwell, 2011-06)
    Optical UBVRI photometry and medium-resolution spectroscopy of the Type Ib supernova SN 2009jf, during the period from ∼ −15 to +250 d, with respect to the B maximum are reported. The light curves are broad, with an extremely ...
  • 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 ...
  • The Peculiar Type Ib Supernova SN 2005bf: Explosion of a Massive He Star with a Thin Hydrogen Envelope? 
    Anupama, G. C; Sahu, D. K; Deng, J; Nomoto, K; Tominaga, N; Tanaka, M; Mazzali, P. A; Prabhu, T. P (University of Chicago Press, 2005-09)
    We present BVRI photometry and optical spectroscopy of SN 2005bf near maximum light. The maximum phase is broad and occurred around 2005 May 7, about 40 days after the shock breakout. SN 2005bf has a peak bolometric magnitude ...
  • 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 ...
  • 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, ...
  • Type Ib supernova 2008d associated with the luminous x-ray transient 080109: an energetic explosion of a massive helium star 
    Tanaka, M; Tominaga, N; Nomoto, K; Valenti, S; Sahu, D. K; Minezaki, T; Yoshii, Y; Yoshida, M; Anupama, G. C; Benetti, S; Chincarini, G; Valle, M. D; Mazzali, P. A; Pian, E (The American Astronomical Society, 2009-02)
    We present a theoretical model for supernova SN 2008D associated with the luminous X-ray transient 080109. The bolometric light curve and optical spectra of the SN are modeled based on the progenitor models and the explosion ...
  • The Unique Type Ib Supernova 2005bf: A WN Star Explosion Model for Peculiar Light Curves and Spectra 
    Tominaga, N; Tanaka, M; Nomoto, K; Mazzali, P. A; Deng, J; Maeda, K; Umeda, H; Modjaz, M; Hicken, M; Challis, P; Kirshner, R. P; Wood-Vasey, W. M; Blake, C. H; Bloom, J. S; Skrutskie, M. F; Szentgyorgyi, A; Falco, E. E; Inada, N; Minezaki, T; Yoshii, Y; Kawabata, K; Iye, M; Anupama, G. C; Sahu, D. K; Prabhu, T. P (The American Astronomical Society, 2005-11-10)
    Observations and modeling for the light curve (LC) and spectra of supernova (SN) 2005bf are reported. This SN showed unique features: the LC had two maxima, and declined rapidly after the second maximum, while the spectra ...
