    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 ...
  • Photometric and spectroscopic evolution of type II-P supernova SN 2004A 
    Gurugubelli, U. K; Sahu, D. K; Anupama, G. C; Chakradhari, N. K (Astronomical Society of India, 2008-09)
    We present optical photometry and spectroscopy of the normal type IIP supernova SN2004A, which was discovered in the galaxy NGC 6207 on 2004 January 9.84UT. Early observations indicated that the supernova was discovered ...
  • Spectroscopic monitoring of the symbiotic star BX monocerotis 
    Anupama, G. C; Kamath, U. S; Gurugubelli, U. K; Mikołajewska, J (Vilnius University and the Lithuanian Astronomical Union, 2012)
    Low resolution optical spectra of the symbiotic star BX Monocerotis in the 3500--9000 A range obtained during 1999--2010 are described. The spectrum of BX Mon at all phases is dominated by the cool component, with a red ...
