  • Emission band photometry of comet Ikeya-Seki (1965f) 
    Bappu, M. K. V; Sivaraman, K. R (Royal Astronomical Society, 1967)
    Photoeletric measures of emission band intensities of C2(I,O) and CN (O,O) of the coma of Comet Ikeya-Seki (1965f)are reported. The measured fluxes are utilized to determine the number of molecules of C2 and CN that ...
  • Emission-line profiles from expanding envelopes 
    Bappu, M. K. V; Menzel, D. H (University of Chicago Press, 1954-05)
    We have developed a method for calculating the emission-line profiles from an expanding envelope. The method applies to an envelope where the emission intensity varies with latitude. Some typically illustrative cases are ...

  • Extended ring system of Uranus 
    Bhattacharyya, J. C; Bappu, M. K. V; Mohin, S; Mahra, H. S; Gupta, S. K (D. Reidel Publishing, 1979-12)
    Two photoelectric records of the occultation event on 10 March, 1977, obtained by two 102-cm-aperture telescopes, spaced 1500 km apart, are critically analyzed and indications of a complex structure of distribution of ...
  • Extinction measurements at Leh 
    Singh, J; Bhattacharyya, J. C; Raveendran, A. V; Mohin, S; Ashoka, B. N (Astronomical Society of India, 1988-03)
    Observations were started at Leh in 1984 with a view to finding the possibility of setting up an astronomical observatory for infrared observations. Results of extinction measurements in UBV bands obtained on 12 nights ...
  • Facility: Vainu Bappu Telescope 
    Bhattacharyya, J. C; Rajan, K. T (Astronomical Society of India, 1992)
  • A Fast Optical Pulse Counting system for Crab Pulsar 
    Santhanam, P; Bhattacharyya, J. C (Indian Institute of Astrophysics, Bangalore, 1985-11)
    A sub millisecond resolution counting system for recording shapes of short periodic pulses is described. Results obtained in recording the shape of optical pulses from Crab pulsar are given here. The flexibility of the ...
  • Fifteenth General Assembly of the I. A. U. 
    Bhattacharyya, J. C (Astronomical Society of India, 1973-09)
  • Flares on AM Canum Venaticorum 
    Marar, T. M. K; Padmini, V. N; Seetha, S; Narayanan Kutty, K. R; Kasturirangan, K; Rao, U. R; Bhattacharyya, J. C (European Southern Observatory, 1988-01)
    AM CVn, an interacting binary system consisting of two helium white dwarfs, has been classified as a nova-like object. Normally it exhibits only small amplitude modulations of 0.05 mag with a 1051 s periodicity. The authors ...
  • Foreword 
    Bappu, M. K. V (1981-09)
  • Further photometric observations of the cataclysmic variable PG 1012-029 
    Ashoka, B. N; Marar, T. M. K; Seetha, S; Kasturirangan, K; Rao, U. R; Bhattacharyya, J. C (Kluwer Academic Publishers, 1993)
    We report time series photometric observations of PG 1012-029, conducted during 1990 and 1991. Light curves of three consecutive eclipses recorded in a single night are presented. The enhanced pre-eclipse hump in our data ...
  • Future Trends in Stellar Spectroscopy 
    Bappu, M. K. V (Astronomical Society of India, 1974-03)
  • Galactic Bulge Hypervelocity (HVS) RR Lyrae Variable Stars and One High Galactic Latitude HVS HB Star 
    Parthasarathy, M (American Astronomical Society, 2024-01)
    Six Galactic Bulge Hypervelocity (HVS) RR Lyrae stars and one high galactic latitude HVS Horizontal Branch (HB) star found from the ongoing search for HVS in the Gaia DR3 and SIMBAD data are presented. Some of these stars ...
  • Gravitational instability of interstellar magnetic clouds 
    Ghosh, K. K; Bhattacharyya, J. C (D. Reidel Publishing Co.,, 1985-12)
    The gravitational instability of a nonrotating isothermal gaseous disk permeated by a uniform frozen-in magnetic field is investigated using a fourth-order perturbation technique. From the results it is found that the disk ...
  • A ground based near infra-red detector system 
    Bhattacharya, J. C (Centre of Advanced Study in Astronomy,Osmania University, 1974)
    The problems connected with observations in the near infra-red from ground based locations are discussed. It is shown that optical telescopes located at high stations in India. can be used effectively for near infra-red ...
