  • Nova V4444 Sagittarii 1999 in the early decline and quiescent phases 
    Kamath, U. S; Ashok, N. M; Anupama, G. C (Astronomical Society of India, 2008-12)
    We present near-infrared and optical spectra of the fast nova V4444 Sagittarii at two single epochs in the early decline phase and unfiltered images obtained in quiescence. Based on this and other available data, we discuss ...
  • Optical Studies of V4332 Sagittarii: Detection of Unusually Strong K I and Na I Lines in Emission 
    Banerjee, D. P. K; Ashok, N. M (University of Chicago Press, 2004)
    We present optical observations of the enigmatic nova-like variable V4332 Sgr. The importance of this object should not be understated since it is considered to be the possible prototype of a new class of eruptive variables. ...
  • Studies of a possible new Herbig Ae/Be star in the open cluster NGC 7380 
    Mathew, B; Banerjee, D. P. K; Ashok, N. M; Subramaniam, A; Bhavya, B; Joshi, V (Chinese Academy of Sciences, 2012-02)
    We present a study of the star 2MASS J22472238+5801214 with the aim of identifying its true nature which has hitherto been uncertain. This object, which is a member of the young cluster NGC 7380, has been variously proposed ...
  • A Study of the Role of Lyβ Fluorescence on O I Line Strengths in Be Stars 
    Blesson, M; Banerjee, D. P. K; Subramaniam, A; Ashok, N. M (IOP Publishing, 2012-07-01)
    The possibility of the Lyβ fluorescence mechanism being operational in classical Be (CBe) stars and thereby contributing to the strength of the O I λ8446 line has been recognized for long. However, this supposition needs ...
