  • Apsidal motion in the binary Delta Orionis 
    Natarajan, V; Rajamohan, R (Kodaikanal Observatory, 1971)
    A velocity curve of the spectroscopic binary 'Delta Orionis' has been obtained from the spectrograms taken at kodaikanal during the years 1968-70. The orbital elements derived are in good agreement with earlier values ...
  • Band-limited integrated scatter measurements on super polished optical mirrors 
    Ventaka, S; Prasad, B. R; Natarajan, V; Kamath, P. U; Kathiravan, S (SPIE-The International Society for Optical Engineering, 2020-08)
    Scattering of light from a surface depends on its microroughness. In general, total integrated scattering of a surface is expressed in terms of root-mean-square microroughness (σrms) using empirical relations. These ...
  • Experimental Validation of a Novel Concept to Reduce Optical Surface Wave Front Errors by Using Deformable Bushes at Opto-Mechanical Interfaces 
    Nagabhushana, S; Prasad, B. R; Nagesh, Suresh; Venkata Suresh, Narra; Sandeep, D. S; Kamath, P. U; Misra, Shalab; Hegde, Bhavana; Utkarsha, D; Sinha, Mrityunjay Kumar; Kathiravan, S; Natarajan, V; Pawan, Kumar; Amit Kumar (World Scientific Publishing, 2022-03)
    One of the major objectives of the optomechanics is to support large optics required for the purpose and also to maintain high dynamic stability in operation. This requirement calls for more number of supports, to support ...
  • Monochromatic polarization measures of comet Ikeya-Seki (1965f) 
    Bappu, M. K. V; Sivaraman, K. R; Bhatnagar, A; Natarajan, V (Royal Astronomical Society, 1967)
  • Photoelectric and Spectrographic Studies of Nova Delphini (1967) 
    Doss, A. T; Bhatnagar, A; Natarajan, V (Kodaikanal Observatory, 1972-07)
    The measurement and analysis of the spectra of Nova Delphini (1967) obtained at Kodaikanal is presented. An estimate of the photospheric temperature of the nuclear star of the nova is also made
  • Some characteristics of sunspot activity within a cycle 
    Ramanathan, A. S; Natarajan, V (The Observatory, 1965-10)
  • Visible emission line coronagraph on Aditya-L1 
    Prasad, B. R; Banerjee, D; Singh, J; Nagabhushana, S; Amit Kumar; Kamath, P. U; Kathiravan, S; Venkata Suresh, Narra; Rajkumar, N; Natarajan, V; Juneja, Madhur; Somu, Pawan; Pant, V; Shaji, Nigar; Sankarsubramanian, K; Patra, Asit; Venkateswaran, R; Adoni, A. A; Narendra, S; Haridas, T. R; Mathew, S. K; Mohan Krishna, R; Amareswar, K; Jaiswa, Bhavesh (Indian Academy of Science, 2017-08-25)
    Solar coronagraph mimics total solar eclipse by blocking the solar disk and enabling the observation of extended coronal atmosphere of the Sun. Visible Emission Line Coronagraph (VELC), on-board Aditya-L1 space mission, ...
  • The Wolf-Rayet eclipsing binary HD 193576 
    Ganesh, K. S; Bappu, M. K. V; Natarajan, V (Kodaikanal Observatory, 1967-10)
