    Near simultaneous optical spectroscopic (on four nights) and broadband linear continuum (B, V, R,and I bands) polarimetric (on seven nights) observations of 29 Be stars were carried out during 1993November-December. The ...
  • Nearly Century-scale Variation of the Sun’s Radius 
    Hiremath, K. M; Rozelot, J. P; Sarp, V; Kilcik, A; Pavan, D. G; Gurumath, S. R (IOP Publishing, 2020-03-10)
    The Kodaikanal Archive Program (India) is now available to the scientific community in digital form as daily digitized solar white light pictures, from 1923 to 2011. We present here the solar radius data, obtained after a ...
  • Nebula around R Corona Borealis

  • Nebular emission lines in IRAS 10215-5916 
    Garcia-Lario, P; Manchado, A; Parthasarathy, M; Pottasch, S. R (European Southern Observatory, 1994-05)
    From low and high resolution spectroscopic observations of IRAS 10215-5916 we have discovered the presence of nebular emission lines in this G-type supergiant star in the post-AGB stage. From its high resolution spectrum ...
  • The nebular hypothesis

  • The nebular hypothesis 
    Sen, N. N (Astronomical Society of India, 1920)
  • Nebular phase observations of the type Ib supernova 2008D/X-ray transient 080109: side-viewed bipolar explosion 
    Tanaka, M; Yamanaka, M; Maeda, K; Kawabata, K. S; Hattori, T; Minezaki, T; Valenti, S; Valle, M. D; Sahu, D. K; Anupama, G. C; Tominaga, N; Nomoto, K; Mazzali, P. A; Pian, E (The American Astronomical Society, 2009-08)
    Abstract We present optical spectroscopic and photometric observations of supernova (SN) 2008D, associated with the luminous X-ray transient 080109, at >300 days after the explosion (nebular phases). We also give flux ...
  • The Nebular Remnant and Quiescent Spectrum of Nova Gk-Persei 
    Anupama, G. C; Prabhu, T. P (Royal Astronomical Society, 1993-07-15)
    CCD images of the nebular shell of the old nova GK Per in [N II] and [O III] emission lines, and also the quiescent spectrum in the optical region, are presented. Proper motion measurements of the knots in [N II]over the ...
  • Nebular spectrum of CPD-56 deg 8032 and He2-113 
    Kameswara Rao, N (Royal Astronomical Society, 1987-09)
    The electron density, temperature and ion abundances in the nebulae surrounding the two WC 10 stars CPD-56 deg 8032 and He2-113 have been estimated. In CPD-56 deg 8032 sulphur, nitrogen and oxygen seem to have solar ...
  • The need for an energy-dependent torsion-coupling constant in the early universe 
    de Sabbata, V; Sivaram, C (Springer, 1989-08)
    The torsion-coupling constant (which depends on energy as E exp -2) can pass through the values of the coupling constants of the other interactions during the evolution of the universe. An energy-dependent torsion-coupling ...
