  • Modelling of a solar coronal loop 
    Krishan, V (Cambridge University Press, 1996-12)
    Montgomery and co-workers have developed a framework to describe the steady state of a turbulent magnetofluid, without the usual recourse to linearization. Thus the magnetic and velocity fields emerge in their fully nonlinear ...
  • Modelling of dust scattering toward the Coalsack 
    Shalima, P; Murthy, J (Royal Astronomical Society, 2004-08)
    Murthy, Henry & Holberg discovered intense far-ultraviolet (FUV) (λλ912-1600) emission from the direction of the Coalsack molecular cloud 10 years ago. We have used their results in conjunction with a Monte Carlo model for ...
  • Modelling of Plasma Structures in the Solar Atmosphere 
    Krishan, V (Indian Institute of Astrophysics, Bangalore, 1984)
    A maximal helicity principle is proposed to study the stability of plasma structures in the solar atmosphere. This principle derives from the statistical treatment of the magnetohydrodynamical turbulence. The steady state ...
  • Modelling of Solar Coronal Oscillations 
    Krishan, V (Indian Institute of Astrophysics, Bangalore, 1997)
    The study of coronal osciallations is important since these oscillations could be responsible for the heating of the solar corona. Coronal structures are ex[ected to undergo three types of oscillations - non-compressional ...
  • Modelling rotation curves -- the turbulent way 
    Prabhu, R. D; Krishan, V (Astronomical Society of India, 1993)
    Helical hydrodynamic turbulence can magnify perturbation seed eddies and this can lead to the appearance of large scale structures. The evolution of the instability is accompanied by a transfer of energy from small scale ...
  • Modelling sunspot equilibrium through a solution of the time dependent MHD equations 
    Gangadhara, R. T; Hasan, S. S (Astronomical Society of India, 1996)
    We numerically simulate the dynamical relaxation to equilibrium of a sunspot. Treating the sunspot as a thick axisymmetric flux tube in cylindrical geometry, we solve the time dependent MHD equation to examine the evolution ...
  • Modelling the diffuse ultraviolet radiation observed by Dynamics Explorer 1 
    Shalima, P; Murthy, J; Fix, J. D (Wiley Blackwell, 2010-10)
    The Dynamics Explorer spacecraft, DE-1, has undertaken two sky surveys in the far-ultraviolet regime, covering a wide variety of Galactic latitudes. We have used a single scattering dust model to probe into the optical ...
  • Modelling the synchrotron light curves in recurrent novae V745 Scorpii and RS Ophiuchi 
    Kantharia, N. G; Dutta, P; Roy, N; Anupama, G. C; Chitale, A; Ishwara-Chandra, C; Prabhu, T. P; Ashok, N. M; Banerjee, D. P. K (Astronomical Society of India, 2015-02)
    In this paper, we present the synchrotron light curve at 610 MHz from the recurrent nova V745 Sco following its outburst on 6 February 2014. The system has been detected and periodically monitored with the Giant Metrewave ...
  • Models for observational signatures of black holes 
    Mohan, Prashanth (Indian Institute of Astrophysics, 2013-09)
  • Models of Flux Tubes from Constrained Relaxation 
    Mangalam, A; Krishan, V (Indian Academy of Sciences, 2000-12)
    We study the relaxation of a compressible plasma to an equilibrium with flow. The constraints of conservation of mass, energy, angular momentum, cross-helicity and relative magnetic helicity are imposed. Equilibria ...
  • Models of force-free spheres and applications to solar active regions 
    Avijeet Prasad; Mangalam, A (Astronomical Society of India, 2013)
    Here we present a systematic study of force-free field equation for simple axisymmetric configurations in spherical geometry. The condition of separability of solutions in radial and angular variables leads to two classes ...
  • Models of highly extended dust shells around R Coronae Borealis 
    Nagendra, K. N; Leung, C. M (Royal Astronomical Society, 1996-08)
    Radiation transport models are constructed for the dust shells of the hydrogen deficient supergiant star R Coronae Borealis (R CrB). IRAS observations of R CrB are used as constraints in selecting the model parameters. ...
  • Models of Highly Extended Dust Shells Around the Supergiants R Coronae Borealis and W Hydrae 
    Nagendra, K. N; Leung, C. M (American Astronomical Society, 1990)
  • Modern astronomy : startling facts 
    Sivaram, C; Arun, K (Ane Books, 2009)
    The year 2009 is being recognised as the international year of astronomy (IYA) to mark the four hundredth anniversary of the historical occasion in the year 1609 when Galileo Galilei used the then newly invented telescope ...
  • Modern optical astronomy: technology and impact of interferometry 
    Saha, S. K (The American Physical Society, 2002-04)
    The present ``state of the art'' and the path to future progress in high-spatial-resolution imaging interferometry is reviewed. The review begins with a treatment of the fundamentals of stellar optical interferometry, the ...
  • Modernisation of the Astrophysical Observatory Kodaikanal 
    Das, A. K (India Meteorological Department, 1960)
  • Modified Titius - Bode Relation 
    Rawal, J. J (Astronomical Society of India, 1978-12)
    The Titius-Bode empirical relation for planetary distances holds as far out as Uranus, but in the cases of Neptune and Pluto, the distances derived from this relation do not agree with the observed values. In the light of ...
  • A modular cryostat for large format and mosaic CCDs 
    Nagaraja Naidu, B; Srinivasan, R; Sagay Nathan, K (Astronomical Society of India, 2001)
    With a growing requirement for wide field imaging, the era of mosaic CCDs is gaining importance in astronomical imaging. Large volume cryostats are needed to house large format and mosaic CCDs. A modular CCD cryostat has ...
  • Modulation in the solar irradiance due to surface magnetism during cycles 21, 22 and 23 
    Jain, K; Hasan, S. S (EDP Sciences, 2004-10)
    Magnetic field indices derived from synoptic magnetograms of the Mt. Wilson Observatory, i.e. Magnetic Plage Strength Index (MPSI) and Mt. Wilson Sunspot Index (MWSI), are used to study the effects of surface magnetism on ...
  • The modulation of radiation in an electron-positron plasma 
    Gangadhara, R. T; Krishan, V; Shukla, P. K (Royal Astronomical Society, 1993-05-01)
    The modulational instability of a large-amplitude, linearly polarized electromagnetic wave propagating in an electron-positron plasma is considered, including the combined effect of relativistic mass variation of the plasma ...
