  • M-Type Dwarfs and the Missing Mass 
    Staller, R. F. A; The, P. S (Astronomical Society of India, 1975-06)
  • MACE telescope : Servo design aspects 
    Mayya, Y. S; Srivatsava, G. P; Koul, R (Astronomical Society of India, 2002)
    The design parameters of the servo system for the MACE imaging Cerenkov telescope, based on functional performance, operational and safety requirements of the system are briefly discussed. the servo system is designed ...
  • Madras Observatory: buildings and instruments 
    Kochhar, R. K (Astronomical Society of India, 1985-09)
    We describe the buildings and the chief instruments of the Madras Observatory (1786-1898), the precursor of the present Indian Institute of Astrophysics through Kodaikanal Observatory.
  • Madras Observatory: The Beginning 
    Kochhar, R. K (Astronomical Society of India, 1985-06)
    We present evidence to show that the Madras Observatory-to which Indian Institute of Astrophysics (IIA) traces its origin-was formed, and observations started, in the year 1786. We also discuss how the erroneous date of ...
  • The Madurai solar radio spectrograph 
    Shanmugaraju, A; Umapathy, S (Astronomical Society of India, 1998)
    The solar radio spectrograph has been constructed at our School of Physics to study the dynamic activities of the sun in metre wavelenght which is quite important for understanding the physics of the outer solar corona. ...
  • The Magnetar Fields 
    Konar, S (Astronomical Society of India, 2003)
    We discuss the nature of evolution of the magnetic field in magnetars
  • Magnetars- A Review 
    Panchapakesan, N (Astronomical Society of India, 2003)
    Magnetars are neutron stars in which a decaying high magnetic field is the source of energy production. The suggestion that magnetars are the dominant source of energy for soft gamma repeaters and anomalous x-ray pulsars ...
  • Magnetic and velocity fields over active regions 
    Gosain, S; Choudhary, D. B (Astronomical Society of India, 2002-09)
    In order to understand the nature of dynamics over an active region (AR) , it is necessary to study the velocity and magnetic fields simultaneously. We present the preliminary results from our analysis of spectropolari ...
  • Magnetic braking and low specific angular momenta of elliptical galaxies 
    Ramadurai, S; Indulekha, K (Astronomical Society of India, 1996)
  • Magnetic field and the ionic tail of comet Halley 
    Krishan, V; Ramadurai, S (Astronomical Society of Indian, 1988-03)
    The space missions to comet Halley have reported an increase of the magnetic field from (12-15) x 10 to the -5th gauss, characteristic of the interplanetary solar wind, to a peak field strength of (70-80) x 10 to the -5th ...
  • Magnetic Field Geometry of 3C111 on pc-scales 
    Kharb, P; Gabuzda, D; Shastri, P (Astronomical Society of India, 2003)
    Multi-epoch Very Long Baseline Polarimetric observations of the Broad Line Radio galaxy 3C111 performed at 8 and 43 GHz after a large millimetre outburst, reveal rapidly evolving parsec-scale radioo structure and the ...
  • Magnetic fields in molecular clouds 
    Ramaprakash, A. N; Gupta, R; Tandon, S. N (Astronomical Society of India, 1998)
  • Magnetic fields in the sun's interior: What do we know about them? 
    Choudhuri, A. R (Astronomical Society of India, 1996)
    The surface observations of the solar magnetic fields put some constraints on the possible magnetic configurations in the Sun's interior. It is currently believed that the solar magnetic fields are generated by a dynamo ...
  • Magnetic helicity in galactic dynamos 
    Subramanian, K (Astronomical Society of India, 2002-09)
    Magnetic fields correlated on kiloparsec scales are seen in spiral galaxies. Their origin ~ould be due to amplification of a small seed field by a turbulent galactic dynamo. We review the current status of the galactic dynamo, ...
  • Magnetic nature of coronal loops 
    Singh, J; Muneer, S; Sakurai, T; Ichimoto, K (Astronomical Society of India, 2007-12)
    It is generally believed that the magnetic pressure is much higher than the gas pressure in the coronal loops and these loops are isothermal in nature. We made systematic observations of four strong coronal emission lines ...
  • Magnetic reconnection 
    Lakhina, G. S (Astronomical Society of India, 2000)
    Magnetic reconnection is considered as a basic plasma process which efficiently converts magnetic energy to plasma kinetic energy companied by changes in the topology of the magnetic field configuration. It prohibites the ...
  • Magneto-ionic conditions and energetics of simultaneous solar microwave bursts at 2.8, 10 and 19.3 GHz on 1980 June 4 
    Degaonkar, S. S; Alurkar, S. K; Bhonsle, R. V; Calla, O. P. N; Lokanadham, B (Astronomical Society of India, 1981-12)
    Simultaneous microwave bursts were observed at 2.8 and 19.3 GHz at Ahmedabad and at 10 GHz at Hyderabad on 1980 June 4. The peak of the burst occurred at 0836, 0838 and 0840 UT at 19.3, 10 and 2.8 GHz respectively, showing ...
  • Magnetoacoustic gravity surface waves with flows 
    Satya Narayanan, A (Astronomical Society of India, 2000)
    The effect of uniform flows on the characteristics of magneto acoustic-gravity surface waves at a single interface when both the magnetic field and the propagation vector are parallel to each other is studied. The region ...
  • Magnetohydrodynamic turbulence in solar wind 
    Verma, M. K (Astronomical Society of India, 1998)
    Alfvenic fluctuations in the solar wind is known to exhibit turbulent behaviour. In this paper we state the existing phenomenologies. After this we show the numerical results from pseudo-spectral method. The numerical ...
  • Magnetohydrostatic equilibrium in solar coronal arcades 
    Chandra, S; Prasad, L (Astronomical Society of India, 1994)
    We present a solution of magnetohydrostatic equations after including the effect of gravity. For low values of the parameters beta, there exist two solutions for the common boundary condition at the base of the corona. ...
