  • Magnetic Imprints of Eruptive and Noneruptive Solar Flares as Observed by Solar Dynamics Observatory 
    Vasantharaju, N; Vemareddy, P; Ravindra, B; Doddamani, V. H (American Astronomical Society, 2022-03-01)
    The abrupt and permanent changes of the photospheric magnetic field in the localized regions of active regions during solar flares, called magnetic imprints (MIs), have been observed for nearly the past three decades. The ...
  • 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 ...
  • Magnetic Shear and Flares 
    Venkatakrishnan, P (International Astronomical Union, 1990)
    Magnetic tension possesses low values at regions of large magnetic “shear” on the polarity inversion line. The low tension allows for a non-force-free field that depends on the density may then possibly evolve into solar ...
  • Magnetic shear in flaring regions. I - Quantitative evaluation of the change in shear 
    Sivaraman, K. R; Rausaria, R. R; Aleem, S. M (Springer Netherlands, 1992-04)
    We have evaluated the shear angle of the neutral line of the non-potential magnetic field for one or two days prior to and after the flare event for 10 cases. We have used the Hagr filament positions to evaluate the shear ...

    Sivaram, C (Deccan Herald, 2006-12-19)
  • Magnetic showers in space 
    Sivaram, C (Deccan Herald, 2006-12-19)
  • Magnetic Structure in Successively Erupting Active Regions: Comparison of Flare-Ribbons With Quasi-Separatrix Layers 
    Vemareddy, P (Frontiers, 2021-10)
    This paper studies the magnetic topology of successively erupting active regions (ARs) 11,429 and 12,371. Employing vector magnetic field observations from Helioseismic and Magnetic Imager, the pre-eruptive magnetic ...
  • Magnetic Transport on the Solar Atmosphere by Laminar and Turbulent Ambipolar Diffusion 
    Hiraki, Y; Krishan, V; Masuda, S (IOP Publishing, 2010-09-10)
    The lower solar atmosphere consists of partially ionized turbulent plasmas harboring velocity field, magnetic field, and current density fluctuations. The correlations among these small-scale fluctuations give rise to ...
  • Magnetic transport on the solar atmosphere by turbulent ambipolar diffusion 
    Krishan, V; Masuda, S (Anita Publications, 2008-12)
    The lower solar atmosphere consists of partially ionized turbulent plasmas harboring velocity field, magnetic field and current density fluctuations. The correlations amongst these small scale fluctuations give rise to ...
  • A magneto-hydrodynamic study of pre-flare loops 
    Hasan, S. S (Institute of Theoretical Astrophysics, 1979)
    The magnetohydrodynamic equilibrium and stability of a configuration which may apply to solar pre-flare loops is analyzed based on the following scenario: (1) the loops exist much prior to the flare and in equilibrium with ...
  • 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 ...
  • 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 ...
