  • Optical spectroscopic and polarization properties of 2011 outburst of the recurrent nova T Pyxidis 
    Pavana, M; Ramya, M. Anche; Anupama, G. C; Ramaprakash, A. N; Selvakumar, G (EDP Sciences, 2019-02)
    Aims. We aim to study the spectroscopic and ionized structural evolution of T Pyx during its 2011 outburst, and also study the variation in degree of polarization during its early phase. Methods. Optical spectroscopic data ...
  • Recurrent novae: Single degenerate progenitors of Type Ia supernovae 
    Anupama, G. C; Pavana, M (Springer, 2020-12)
    Type Ia supernovae are the result of explosive thermonuclear burning in CO white dwarfs. The progenitors of the Ia supernovae are white dwarfs in an interacting binary system. The donor companion is either a degenerate ...
  • Spectroscopic and geometrical evolution of the ejecta of the classical nova ASASSN-18fv 
    Pavana, M; Raj, A; Bohlsen, T; Anupama, G. C; Gupta, R; Selvakumar, G (Oxford University Press on behalf of the Royal Astronomical Society, 2020-05)
    The optical spectroscopic observations of ASASSN-18fv observed from 2018 March 24 to 2019 January 26 are presented. The optical spectra are obtained from Mirranook, Vainu Bappu, and South African Astronomical observatories. ...

    Pavana, M; Raj, A; Bohlsen, T; Anupama, G. C; Gupta, R; Selvakumar, G (Oxford University Press on behalf of the Royal Astronomical Society, 2020-06)
    The optical spectroscopic observations of ASASSN-18fv observed from 2018 March 24 to 2019 January 26 are presented. The optical spectra are obtained from Mirranook, Vainu Bappu, and South African Astronomical observatories. ...
  • 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 ...
