    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 ...
  • 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 ...
  • 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 ...
  • 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 ...

D; Svinkin, D; Thone, C. C; de Ugarte Postigo, A; Urata, Y; Weinstein, A (IOP Publishing, 2015-06)
    The Fermi Gamma-ray Space Telescope has greatly expanded the number and energy window of observations of gamma-ray bursts (GRBs). However, the coarse localizations of tens to a hundred square degrees provided by the Fermi ...
  • Srivastava, R. K (Astronomical Society of India, 1998)
  • Pandey, G; Lambert, D. L (IOP Publishing, 2011-02)
    A non-LTE (NLTE) abundance analysis was carried out for three extreme helium stars (EHes): BD+10° 2179, BD–9° 4395, and LS IV+6° 002, from their optical spectra with NLTE model atmospheres. NLTE TLUSTY model atmospheres ...
  • Raju, K. P; Singh, J (IOP Publishing, 2014-02)
    The Ca II K filtergrams from Kodaikanal Solar Observatory have been used to study solar activity. The images are dominated by the chromospheric network and plages. Programs have been developed to obtain the network and ...
  • Vagiswari, A; Louis, C (Astronomical Society of the Pacific, 1998)
    A brief description of the proposed networking of astronomy libraries in India is given. Three models are identified which may be introduced successively as and when all eight libraries acquire necessary software and hardware.
  • Ramadurai, S (Astronomical Society of India, 1975-03)
  • Datta, B; Sivaram, C; Ghosh, S. K (Springer, 1985-04)
    Several independent considerations which rule out the hypothesis that the missing mass in galactic halos is composed of massive neutral fermions such as neutrinos, gravitinos, or photinos are discussed. It is found that ...
  • D'Olivo, J. C; Nieves, J. F; Palash, B. P (Elsevier B.V., 1996-05)
    We consider the Čerenkov radiation emitted by neutrinos due to their effective electromagnetic interactions as they pass through a polarisable medium. The effect exists even for massless, chiral neutrinos, and no physics ...
  • Sivaram, C (Kluwer Academic Publishers, 1989)
    Neutrino burst observations from SN1987A indicate that the density and the temperature of the source and the propagation of the neutrinos in the medium are markedly different from those of solar and terrestrial conditions. ...
  • Ramadurai, S; Schramm, D. N (Astronomical Society of India, 1993)
    The detection of neutrinos from SN1987a has revived the interest in neutrino induced nucleosynthesis. In this work various results on the neutrino produced abundances of several isotopes are summarized and compared with ...
  • de Sabbata, V; Sivaram, C (Italian Physical Society, 1990-05)
    The authors consider a spin-torsion coupling for neutrinos in the early universe and show that a neutrino magnetic moment can be present also for zeromass neutrinos. They make an estimate of this induced magnetic moment ...
