    The effects of spacetime curvature and rotation on the pulse profile of fast pulsars are studied using a rotationally perturbed spherical metric and a representative choice of the equation of state for neutron star matter. ...
  • Search for optical bursts from the gamma ray burst source GBS 0526-66 
    Seetha, S; Sreenivasaiah, K. V; Marar, T. M. K; Kasturirangan, K; Rao, U. R; Bhattacharyya, J. C (NASA/STI, 1985-08)
    Attempts were made to detect optical bursts from the gamma-ray burst source GBS 0526-66 during Dec. 31, 1984 to Jan. 2, 1985 and Feb. 23 to Feb. 24, 1985, using the one meter reflector of the Kavalur Observatory. Jan. 1, ...
  • Homologous microwave bursts and associated solar flares 
    Gopala Rao, U. V (D. Reidel Publishing Company, 1970-10)
    Homologous characteristics of radio bursts at 3000 MHz and associated optical flares are studied. It is found that flares associated with homologous radio bursts are also homologous optically.
  • Variation in continuum brightness and equivalent widths of lines in sunspot penumbrae 
    Bhatnagar, A (Springer - Verlag, 1966)
    Variations in the continuum brightness and in the equivalent widths of lines have been observed in the sunspot penumbral spectra. Darker regions in the continuum of the penumbrae show widening of lines, while the brighter ...
  • A technique for measurement of rotational frequency 
    Das, G. C (D. Reidel Publishing Co., 1979-12)
    On the basis of Chandrasekhar's proposition that the Coriolis force has an influence on the magnetohydrodynamic waves excited in cosmic phenomena, a simple approximate formula determining the rotational frequency from the ...
  • Decameter radio emission from Jupiter and solar activity 
    Sastry, Ch. V (Elsevier Science, 1968-09)
    It is found that there is an apparent increase in solar activity prior to the emission of decametric radio bursts from Jupiter during years of high solar activity. It is pointed out that Jupiter data contains artificial ...
  • Structures in Saturn's Magnetosphere 
    Bhattacharyya, J. C (Indian Academy of Sciences, 1995-12)
  • The pulses as a diagnostic technique in the sun 
    Das, G. C (D. Reidel Publishing Co., 1980-08)
    A method of finding physical parameters by studying the pulses in the sun is discussed. Consideration is given to an ideal highly relevant model which could exist in the sun with the effects of ionization, due to which ...
  • Radio emission from an intense electromagnetic beam-plasma system 
    Krishan, V (D. Reidel Publishing Co., 1979-06)
    Interaction of a high-intensity and low-frequency electromagnetic beam with a plasma is investigated. The dynamics of plasma particles under this strong electromagnetic field is calculated without using the perturbation ...
  • Eigenfrequencies of radial pulsations of strange quark starsEigenfrequencies of radial pulsations of strange quark stars 
    Datta, B; Sahu, P. K; Anand, J. D; Goyal, A (Elsevier, 1992-06)
    We calculate the range of eigenfrequencies of radial pulsations of stable strange quark stars, using the general relativistic pulsation equation and adopting realistic equation of state for degenerate strange quark matter.
  • Detection of a branching-off feature from the Cygnus-Orion arm in the direction of Carina 
    Babu, G. S. D (Elsevier Science B.V., 1988)
    A program is presented for the study of faint young open clusters in the anticenter direction of the Galaxy with the aim of using these clusters as spiral arm tracers. Twelve open clusters are selected for observation. ...
  • Frequency response of magnetic flux sheaths 
    Venkatakrishnan, P (D. Reidel Publishing Co., 1979-08)
    When a sound wave is incident on a magnetic flux sheath, it causes fluctuations in the mean magnetic field of the sheath. We have calculated the space-average of the longitudinal component of these fluctuations and plotted ...
  • Cosmic separation of phases, density inhomogeneities and primordial nucleosynthesis 
    Rana, N. C; Datta, B; Raha, S; Sinha, B (Elsevier, 1990-04)
    The authors investigate the role of the cosmic QCD phase transition on the relative abundances of light elements in primordial nucleosynthesis, with particular attention on the so-called 7Li over-production problem.
  • Oscillations In Galaxies 
    Namboodiri, P. M. S (Kluwer Academic Publishers, 2000-01)
    Oscillations in galaxies have been investigated by numerical simulations. The various models used have density distributions corresponding to that of polytrope of index n in the range 0 ≤ n ≤ 4 and their evolution has been ...
  • Planetary heat flow limits on monopole and axion fluxes 
    Sivaram, C (D. Reidel Publishing Co., 1987-02)
    Recent improvements in the quantitative estimates of the observed heat flow from planetary objects of the solar system may be used to put rather stringent limits on any background monopole flux. The axion flux from the ...
  • New telescopes in India 
    Bhattacharyya, J. C (D. Reidel Publishing Co., 1986-01)
    The review covers the description and present status of the two optical/infrared telescopes designed and presently near fabrication in India. The 234 cm aperture optical telescope expected to be installed at Kavalur shortly ...
  • Directivity of solar microwave bright regions 
    Gopala Rao, U. V (D. Reidel Publishing Company, 1968-08)

    Sharma, D. P; Marar, T. M. K; Seetha, S; Kasturirangan, K; Rao, U. R; Bhattacharyya, J. C (INSDOC, 1983-08)
    High speed optical photometric observations of the hard X-ray source EX Hya, carried out with the reflector of the Kevalur Observatory, are presented. The observations with time resolutions of 1 s or 2 s were made on four ...
