  • 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 ...

    Naik, S; Pandey, J. C; Naik, S; Savanov, I. S; Raj, A. (Societe Royale des Sciences de Liege, 2019-10)
    We present results obtained from the studies of magnetic activities on four solar-type stars (F-type star KIC 6791060, K-type star LO Peg, and two M-type planet-hosting stars K2–33 and EPIC 211901114) by using optical ...
  • Magnetic activity affects climate 
    Deccan Herald (Deccan Herald, 2007-01-05)
  • Magnetic Activity and the Enhanced 5303 Ã Emission in Solar Active Regions 
    Ramesh, K. B; Nagabhushana, B. S; Varghese, B. A (Springer, 2001-03)
    Analysis of the intensity maps of Fexiv emission at λ=5303 Å obtained from the observations of ground-based coronagraphs during the sunspot minimum period 1985 and 1986 shows the persistent presence of localized strong ...
  • Magnetic activity in the photosphere of CoRoT-Exo-2a. Active longitudes and short-term spot cycle in a young Sun-like star 
    Lanza, A. F; Pagano, I; Leto, G; Messina, S; Aigrain, S; Alonso, R; Auvergne, M; Baglin, A; Barge, P; Bonomo, A. S; Boumier, P; Collier Cameron, A; Comparato, M; Cutispoto, G; de Medeiros, J. R; Foing, B; Kaiser, A; Moutou, C; Parihar, P. S; Silva-Valio, A; Weiss, W. W (EDP Sciences, 2009-01)
    Context: The space experiment CoRoT has recently detected transits by a hot Jupiter across the disc of an active G7V star (CoRoT-Exo-2a) that can be considered as a good proxy for the Sun at an age of approximately 0.5 ...
  • 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 and velocity properties of G-band bright points around a pore 
    Rangarajan, K. E; Sankarasubramanian, K; Nagaraju, K (Astronomical Society of the Pacific, 2009-06)
    Physical properties of G-band bright points (GBPs) surrounding a pore are studied using observations spanning from photosphere to chromosphere. The magnetic field strengths obtained in these bright points are of the order ...
  • Magnetic braking and low specific angular momenta of elliptical galaxies 
    Ramadurai, S; Indulekha, K (Astronomical Society of India, 1996)

    Sahoo, B. K; Gopakumar, G; Chaudhuri, R. K; Das, B. P; Merlitz, H; Mahapatra, U. S; Mukherjee, D (The American Physical Society, 2003-10)
    The relativistic coupled-cluster method is applied to calculate the magnetic dipole hyperfine constant “A” of the 6s1/2, 6p1/2, 6p3/2, and 5d3/2 states of singly ionized barium. After the inclusion of two-body correlation ...
  • The magnetic disturbance field at kodaikanal 
    Thiruvengadathan, A (The Manager Government of India Press, Simla, 1956-10)
    The magnetic disturbance field at Kodaikanal has been studied, using the data for the period March 1950 to February 1954. As far as the horizontal magnetic field is concerned, it is found that the form of the disturbance ...
