  • 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 ...
  • Magnetoacoustic wave propagation in off-limb polar regions 
    O'Shea, E; Banerjee, D; Doyle, J. G (EDP Sciences, 2006-02)
    Aims.To find evidence of magnetoacoustic waves in off-limb polar regions. Methods.Using temporal series data from the Coronal Diagnostic Spectrometer (CDS) on SOHO, we study oscillations found in radiant flux and velocity ...
  • Magnetoatmospheric oscillations in sunspot umbrae 
    Hasan, S. S (The American Astronomical Society, 1990-01)
    The nature of umbral oscillations is investigated using an empirical model for the sunspot umbra, based on the model of Maltby et al. (1986). Approximating the sunspot as a thick flux tube of circular cross section, the ...
  • Magnetoconvective flows and waves in the lower solar atmosphere 
    Sangeetha, C. R (Indian Institute of Astrophysics, 2017-01)
    Sun has complex magnetic features like sunspots, magnetic bright points, plages, network fields, filaments, etc. These complex magnetic features are found to be associated with various observed dynamical phenomenons like ...
  • Magnetohydrodynamic equilibrium and stability of pre-flare loops - Constant pitch field 
    Hasan, S. S (D. Reidel Publishing Co.,, 1980-08)
    The equilibrium and stability of a loop in which energy storage occurs prior to a solar flare is discussed. Working on the hypothesis, that the onset of the flare begins only after sufficient magnetic energy has been stored ...
  • Magnetohydrodynamic Phenomena in Solar Atmosphere 
    Banerjee, D (Indian Institute of Astrophysics, Bangalore, 1996-12)
  • Magnetohydrodynamic simulation of the X9.3 flare on 2017 September 6: evolving magnetic topology 
    Jiang, C; Zou, P; Feng, X; Hu, Qiang; Liu, Rui; Vemareddy, P; Duan, Aiying; Zuo, P; Wang, Yi; Wei, Fengsi (IOP Publishing, 2018-12-10)
    Three-dimensional magnetic topology is crucial to understanding the explosive release of magnetic energy in the corona during solar flares. Much attention has been given to the pre-flare magnetic topology to identify ...

  • 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 ...
  • Magnetohydrodynamic waves in open coronal structures 
    Banerjee, D; Krishna Prasad, S; Pant, V; McLaughlin, J. A; Antolin, P; Magyar, N; Ofman, L; Tian, H; Van Doorsselaere, T; De Moorte, I; Wang, T. J (Springer Nature B.V, 2021-10)
    Modern observatories have revealed the ubiquitous presence of magnetohydrodynamic waves in the solar corona. The propagating waves (in contrast to the standing waves) are usually originated in the lower solar atmosphere ...
  • Magnetohydrodynamic waves in the solar corona 
    Satya Narayanan, A; Ramesh, R (Anita Publications, 2005)
  • 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. ...
  • Magnetohydrostatic equilibrium in starspots: dependences on color (Teff) and surface gravity (g) 
    Rajaguru, S. P; Hasan, S. S (Cambridge University Press, 2011-08)
    Temperature contrasts and magnetic field strengths of sunspot umbrae broadly follow the thermal-magnetic relationship obtained from magnetohydrostatic equilibrium. Using a compilation of recent observations, especially in ...
  • Magnetorotational instability in accretion disks 
    Krishan, V; Mahajan, S. M (Springer Netherlands, 2008)
    Accretion disks are a basic and an ubiquitous construct of nature. We describe their formation, briefly and qualitatively, in diverse astrophysical situations. These systems, though controlled by the gravitational forces, ...
  • Magnitudes and colours of some members of the Perseus Cluster 
    Bappu, M. K. V (Royal Astronomical Society, 1954)
    Photoelectric colours and magnitudes have been determined for twenty-five stars considered to be members of the moving cluster in Perseus. A distance modulus of 6m.83, corresponding to a distance of 230 ps, has been derived. ...
  • MAGSAT and Geodynamo 
    Singh, B. P (Indian Institute of Astrophysics, Bangalore, 1988)
    Accurate, uniform and global vector magnetic field data obtained by MAGSAT provided a high resolution model of the earth’s magnetic field. It became possible to separate the core and crustal parts in spherical harmonic ...
  • Making Good Use of Bad Weather: Finding Extremely Metal-Poor Stars in the Clouds 
    Placco, V. M; Beers, T. C; Rossi, S; Kennedy, C; Christlieb, N; Lee, Y. S; Sivarani, T (Astronomical Society of the Pacific, 2012-12)
    Current results are presented for a new survey effort to search for Extremely Metal-Poor (EMP) and Carbon Enhanced Metal-Poor (CEMP) stars from the Hamburg / ESO objective-prism survey (HES). These stars are important ...
  • The man mandir of benares 
    Bose, P. C (Astronomical Society of India, 1918)
  • Managing the contents of Indian Institute of Astrophysics (IIA) Archives - Copyright Issues 
    Birdie, C; Vagiswari, A (Astronomical Society of the Pacific, 2010)
    Archives and museums all over the world face challenges in facilitating the access to their contents and also protecting the rights of the author, more so, in the case of unpublished works. At the Indian Institute of ...
