  • IPS observations of the solar wind at 327 MHz - A comparison with ULYSSES observations 
    Janardhan, P; Balasubramanian, V; Ananthakrishnan, S; Srivatsan, R (Astronomical Society of India, 1996)
    Extensive IPS observations at 327 MHz using the Ooty Radio Telescope (ORT) are presented. The observations spanning two and a half years starting in September 1992 covered two important periods during the Ulysses south ...
  • IPS survey at 327 MHz for detection of compact radio sources 
    Balasubramanian, V; Janardhan, P; Ananthakrishnan, S; Manoharan, P. K (Astronomical Society of India, 1993)
    In early 1992 a new feed was installed along the focal line of the 530 m long and 30 m wide parabolic cylinder reflector of the Ooty Radio Telescope (ORT). The new feed consisting of 1056 GaAsFET low noise amplifiers, one ...
  • IR observations of Am stars 
    Shylaja, B. S; Ashok, N. M (Astronomical Society of India, 2002)
    The IR observations of chemically peculiar stars are carried out and compared with the previous data in IR and far IR from IRAS. The flux redistribution appears to be a common phenomenon in all the stars of this class. The ...
  • IR Spectroscopy of Nova-like Sources 
    Banerjee, D. P. K; Ashok, N. M (Astronomical Society of India, 2003)
    Near - IR spectroscopic and photometric observations of the eruptive variables V838 Mon and V445 Puppis in the J H K bands are reported. These objects erupted in nova-like explosions but evolved into rather unique and ...
  • IR-IMAC - A developmental approach 
    Vidhya, V; Kamath, U. S; Vidhya, R (Astronomical Society of India, 2004-03)
    IR-IMAC is a multi-utility software package developed to remotely control the Near-Infrared imager installed on the 2-metre Himalayan Chandra Telescope at Mt. Saraswati, Hanle. The core idea in the development of IR-IMAC ...
  • Is HR 2947 a variable? 
    Kameswara Rao, N; Ashok, N. M; Kulkarni, P. V (Astronomical Society of India, 1981-06)
    Observations of HR 2947 show that it is fainter by 0.3 mag in V compared to the magnitude listed by Cowley et al. (1969). The energy distribution from 1565 Armstrong to 1.25 micro is similar to that of a B5 III star and ...
  • Is the Gravitational Constant, G, Changing with Time? 
    Narlikar, J. V (Astronomical Society of India, 1974-12)
  • Isolated pairs of spiral galaxies--a statistical study of far infrared and microwave characteristics 
    Venugopal, V. R; Narasimhan, K. S. V. S (Astronomical Society of India, 1993-06)
    A statistical study of the far infrared and microwave (lambda 6.3 cm ) lumnosities of a sample of isolated pairs of spiral galaxies and a comparison sample on non-interacting galaxies selected from the lists given by ...
  • IUCAA 2 meter telescope and its first light instrument IFOSC 
    Gupta, R; Burse, M; Das, H. K; Kohok, A; Ramaprakash, A. N; Engineer, S; Tandon, S. N (Astronomical Society of India, 2002-09)
    The various features of the IUCAA 2-meter telescope, its site parameters and considerations made for preserving the local seeing in terms of ventilation, thermal emissivity of the dome etc are described. The first ...
  • Japanese radio astronomy - Past, present, and future. 
    Deguchi, S (Astronomical Society of India, 1995)
    The past, present and future of radio astronomy in Japan are described form the author's personal view point. The radio astronomy in Japan is quickly growing in terms of the telescope size, the budget scale, and the total ...
  • JHK Spectroscopy of the Enigmatic Variable V445 Puppis 
    Ashok, N. M; Banerjee, D. P. K (Astronomical Society of India, 2003)
    Near-IR spectroscopic observations are reported for the enigmatic, nova-like, variable V445 Puppis. The near-IR spectra are hydrogen-deficient and unusually rich in CI lines. The spectra indicate that the object could be ...
  • A Journey to the Centre of a Neutron Star 
    Chitre, S. M (Astronomical Society of India, 1973)
  • Joys and frustration - A scientist's diary 
    Alurkar, S. K (Astronomical Society of India, 1997)
  • Jupiter, the Giant Planet 
    Mitchell, J (Astronomical Society of India, 1915)
  • Jupiter`s Magnetic Field 
    Venkatavaradan, V. S (Astronomical Society of India, 1975-03)
  • Kinematics of diffuse interstellar clouds: recent GMRT results 
    Dwarakanath, K. S (Astronomical Society of India, 2004-09)
    high latitude HI 21 cm-line absorption survey towards extragalactic sources was recently completed using the Giant Meterwave Radio Telescope (GMRT). A total of 104 sources with |b|>15o and with a 21 cm ¤ux density greater ...
  • Kinematics of molecular gas in the nucleus of barred galaxies : NGC 253 and M82 
    Das, M (Astronomical Society of India, 2000)
    In more than half of all observed spiral galaxies, the central molecular gas is distributed in a bar. Since gas is a dissipative fluid, it will tend to settle along closed orbits in the plane of a galaxy. Simulations of ...
  • Kinematics of Vega-like stars 
    Manoj, P; Bhatt, H. C (Astronomical Society of India, 2001)
    We have studied the kinematics of Vega-like stars in the solar neighbourhood. Space velocities are computed for 80 Vega-like stars. We analyse the space velocities of these stars in connection with the young stellar ...
  • The Kitt Peak Coronal Velocity Experiment 
    Livingston, W; Harvey, J; Doe, L. A; Gillespie, B; Ladd, G (Tata Institute of Fundamental Research, Bombay, 1980-06)
    Multi-slit spectra of (Fe XIV 5303) plus neon comparisons were successfully obtained on February 16, 1980 at the Japal-Rangapur site. The objective is to confirm our previous results of March 1970 and June 1973, viz. that ...
