  • On the accuracy of the caustic test 
    Banerjee, D. P. K; Willstrop, R. V; Anandarao, B. G (Astronomical Society of India, 1999)
  • 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. ...
  • Optical/IR studies of Be stars in NGC 6834 with emphasis on two specific stars 
    Mathew, B; Varricatt, W. P; Subramaniam, A; Ashok, N. M; Banerjee, D. P. K (IOP Publishing, 2014-09)

M; Srivastav, S; Sullivan, M; Suntzeff, N. B; Surace, J; Wozniak, P. R; Yaron, O (EDP Sciences, 2015-06)
    We present near-infrared (NIR) time-series spectroscopy, as well as complementary ultraviolet (UV), optical, and NIR data, of the Type Ia supernova (SN Ia) iPTF13ebh, which was discovered within two days from the estimated ...
  • 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 ...
  • Studies of the peculiar nova V4332 Sgr 
    Banerjee, D. P. K (Astronomical Society of India, 2005-06)
    We discuss our recent observations of the interesting but enigmatic nova-like variable V4332 Sgr. The object shows a remarkably rich near-infrared and optical spectrum with several unusual spectral features generally not ...
  • 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 ...
  • Velocity field structure in the Orion Nebula 
    Seema, P; Banerjee, D. P. K; Anandarao, B. G (Astronomical Society of India, 1993)
    High quality interferograms have been obtained on the H II region in the Orion Nebula in the emission line of (OIII) 5007 A using the high resolution imaging Fabry-Perot spectrometer. Velocity profiles were obtained for ...
