  • Integrated brightness and colour of Omega Centauri 
    Scaria, K. K (Astronomical Society of India, 1982-12)
    Integrated magnitudes in U, B, V, R and I bands are calculated for the globular cluseter Omega Centauri. The observed radial chaange in the integrated colour of the cluster shows that the cluster core (r<2') is redder in ...
  • Behaviour of some neutral molecular absorption lines in facula models 
    Tripathi, B. M; Sinha, K; Pande, M. C (Astronomical Society of India, 1982-12)
    The equivalent widths of some selected absorption lines of C2, Ch, MgH, NH, OH and SH molecules in five facula and two photospheric models have been calculated under the assumption of LTE. The calculations reveal that the ...
  • Vibration-rotation bands of SiH and MgH in sunspot spectra 
    Sinha, K; Joshi, G. C (Astronomical Society of India, 1982-12)
    We have calculated the equivalent widths of the vibration-rotation bands of SiH and MgH molecules for a possible detection in the sunspot spectrum. Five different models were utilized and the results obtained with and ...
  • Photometric solution for the eclipsing binary TT Aurigae 
    Abhyankar, K. D; Rajasekhar Rao, N; Lokanadham, B (Astronomical Society of India, 1982-12)
    Photometric elements of TT Aur are derived from the UBV observations of the star during 1973-77. The system is found to be detached but quite close. Absolute dimensions are obtained on the basis of the spectroscopic element ...
  • Light-time effect in AK Her and ER Ori 
    Abhyankar, K. D; Panchatsaram, T (Astronomical Society of India, 1982-12)
    An analysis of the minimum-time data of AK Her and ER Ori revelas possible sinudodal variations in their orbital periods. In the case of AK Her we suspect two additional components; one of mass 0.2 to 0.4 MSun with a period ...
  • Relativistic beams, thick accretion disks and active galactic nuclei 
    Wiita, P. J; Kapahi, V. K; Saikia, D. J (Astronomical Society of India, 1982-12)
    We review recent analyses of observations of radio galaxies and quasars that support the relativistic beaming models and appear to produce values for the Lorentz factors of the radiating mateiral in the nuclear jets. Thick ...
  • The Be star phenomena I. General properties 
    Kogure, T; Hirata, R (Astronomical Society of India, 1982-12)
    General properties of Be stars including their variabilities are considered. The Be stars are first defined as non-supergiant B stars with emission-lines including non-emission shell stars. The percentage fraction of Be/B ...
  • Tidal disruption in colliding galaxies 
    Narasimhan, K. S. V. S; Alladin, S. M (Astronomical Society of India, 1982-09)
    Distruptive effects in colliding galaxies due to their mutual tidal interaction are compared under the impulsive approximation. If M1 and M2 are the masses and Rho1 and Rho2 the densities of the two galaxies, M2 suffers ...
  • Analysis of the light variations of BS Aquarii 
    Kilambi, G. C (Astronomical Society of India, 1982-09)
    An analysis of UBV light variations of BS Aqr is presented. Intrinsic (U-B) and (B-V) values are used to derive the temperature and surface gravity. The mean values are Teff = 7600 + or - 100 K and log geff = 3.8 + or - ...
  • On MgH line intensities in sunspot unbrae 
    Sinha, K (Astronomical Society of India, 1982-09)
    The line intensities of the umbral MgH molecules reported by Sotirovski (1971) are re-analysed utilizing the latest laboratory data. It appears probable that because of a neglect of the role of blurring in producing stray ...
  • Places of formation of nineteen nearby classical Cepheids 
    Joshi, U. C (Astronomical Society of India, 1982-09)
    Places of formation of 10 nearby classical Cepheids have been computed in a model of our Galaxy which has axisymmetric and spiral-like components. For the axisymmetric components Schmidt's (1965) model is used, and spiral-like ...
  • Surge prominence of 1981 November 19 
    Verma, V. K; Pande, M. C (Astronomical Society of India, 1982-09)
    Time-lapse photographic observations with 0.7 Armstrong passband H-alpha filter and the morphological behaviour of the surge prominence recorded on 1981 Novermber 19 have been described. The surge was recorded both in the ...
