  • First evidence of the possible detection of diffuse circumstellar bands in AGB descendants 
    Di­az-Luis, J. J; Garcia-Hernandez, D. A; Kameswara Rao, N; Manchado, A; Cataldo, F (Societa Astronomica Italiana, 2016-06)
    The short transition phase between asymptotic giant branch stars (AGB; when circumstellar envelopes rich in small organic molecules are efficiently created) and planetary nebulae (PNe) represents a most active phase of ...
  • Optical and Near-infrared Study of Nova V2676 Oph 2012 
    Raj, A; Das, R. K; Walter, F. M (IOP Publishing, 2017-02-01)
    We present optical spectrophotometric and near-infrared (NIR) photometric observations of the nova V2676 Oph covering the period from 2012 March 29 through 2015 May 8. The optical spectra and photometry of the nova have ...
  • 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 ...
  • V2676 Oph: Estimating Physical Parameters of a Moderately Fast Nova 
    Raj, A; Pavana, M; Kamath, U. S; Anupama, G. C; Walter, F. M (Copernicus Foundation for Polish Astronomy, 2018-03)
    Using our previously reported observations, we derive some physical parameters of the moderately fast nova V2676 Oph 2012 #1. The best-fit CLOUDY model of the nebular spectrum obtained on 2015 May 8 shows a hot white dwarf ...
