  • 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 ...

  • A photometric study of F-type stars of high galactic latitude 
    Ferro, A. A; Giridhar, S; Chavez, M; Parrao, L (European Southern Observatory, 1989-04)
    Photometry in the O I 7774 A line and the uvbybeta system is presented for a group of high Galactic latitude F-type luminosity type I stars. The results indicate that the candidates are high gravity near solar Fe/H abundance ...
  • Photometric Study of HD224085 
    Raveendran, A. V; Mohin, S; Mekkaden, M. V (Royal Astronomical Society, 1981-07)
    B and V photometry of HD 224085 obtained on 21 nights between 1979 November and 1980 February is presented. The amplitudes of light variation observed are ~ 0.15mag in both B and V. The photometric period is found to be ...
  • Photometric study of the lines of hydrogen and of calcium in the fraunhofer spectrum at different points of the Sun's disc
