  • Kinematics of two dwarf galaxies in the NGC 6946 group 
    Begum, A; Chengalur, J. N (EDP Sciences, 2004)
    We present high velocity resolution (~ 1.6 km s -1) Giant Meterwave Radio Telescope (GMRT) HI 21 cm synthesis images of the dwarf galaxies KK98 250 and KK98 251, as well as optical broad band images of KK98 250. We find ...
  • Kinematics of Vega-like stars: Lifetimes and temporal evolution of circumstellar dust disks 
    Manoj, P; Bhatt, H. C (EDP Sciences, 2005-01)
    We have used the velocity dispersion as an age indicator to constrain the ages of a large sample of main sequence Vega-like stars in order to study the lifetimes and temporal evolution of the dust disks around them. We use ...
  • Kinetic Equilibria of Accretion Discs 
    Bhaskaran, P; Krishan, V (Springer, 1995-10)
    A kinetic description of the equilibrium structure of accretion disc plasma is presented. It is possible to have an equilibrium configuration for a stationary axisymmetric gravitating plasma disc with spatial gradients in ...
  • Kinetic theory of Jeans instability of a dusty plasma 
    Pandey, B. P; Lakhina, G. S; Krishan, V (The American Physical Society, 1999-12)
    A kinetic theory of the Jeans instability of a dusty plasma has been developed in the present work. The effect of grain charge fluctuations due to the attachment of electrons and ions to the grain surface has been considered ...
  • King Comet

  • Kink and Longitudinal Oscillations in the Magnetic Network on the Sun: Nonlinear Effects and Mode Transformation 
    Hasan, S. S; Kalkofen, W; van Ballegooijen, A. A; Ulmschneider, P (The American Astronomical Society, 2003-03)
    We examine the propagation of kink and longitudinal waves in the solar magnetic network. Previously, we investigated the excitation of network oscillations in vertical magnetic flux tubes through buffeting by granules and ...
  • Kink oscillations in the solar corona 
    Satya Narayanan, A; Ramesh, R; Kathiravan, C; Ebenezer, E (Astronomical Society of the Pacific, 2004-12)
    The solar coronal plasma is highly structured in the magnetic field, density and temperature. This plays a crucial role in the theory of MHD oscillations. In this study, we model a coronal loop to be made up of a cylindrical ...

W; Akitaya, H; Aldering, G; Arimatsu, K; Contreras, C; Horiuchi, T; Hsiao, E. Y; Itoh, R; Iwata, I; Kawabata, K. S; Kawai, N; Kitagawa, Y; Kokubo, M; Kuroda, D; Mazzali, P; Miswava, T; Moritani, Y; Morrell, N; Okamoto, R; Pavlyuk, N; Phillips, M. M; Pian, E; Sahu, D. K; Saito, Y; Sano, K; Stritzinger, M. D; Tachibana, Y; Taddia, F; Takaki, K; Tateuchi, K; Tomita, A; Tsvetkov, D; Ui, T; Ukita, N; Urata, Y; Walker, E; Yoshii, T (Published by Oxford University Press on behalf of the Astronomical Society of Japan, 2014-12)
    The Kiso Supernova Survey (KISS) is a high-cadence optical wide-field supernova (SN) survey. The primary goal of the survey is to catch the very early light of a SN, during the shock breakout phase. Detection of SN shock ...
  • Kodai school on solar physics : Kodaikanal, India, 10-22 December 2006 
    Hasan, S. S (editor); Banerjee, D (editor) (American Institute of Physics, 2007)
    What is this work? Nothing less than a must-read for graduate students working in the field of astrophysics, specifically on theoretical and observational problems in solar physics. The Kodaikanal School on Solar Physics ...
  • Kodaikanal digitized white-light data archive (1921-2011): Analysis of various solar cycle features 
    Mandal, Sudip; Hegde, M; Samanta, T; Hazra, G; Banerjee, D; Ravindra, B (EDP Sciences, 2017-05)
    Context. Long-term sunspot observations are key to understanding and predicting the solar activities and its effects on space weather. Consistent observations, which are crucial for long-term variations studies, are generally ...

    The Indian Institute of Astrophysics (IIA) has commissioned a low frequency (<100 MHz) spectrograph at its Kodaikanal Solar Observatory (KSO) for coordinated observations of transients in the solar atmosphere with other ...
  • Kolmogorov dissipation scales in weakly ionized plasmas 
    Krishan, V; Yoshida, Z (Royal Astronomical Society, 2009-06)
    In a weakly ionized plasma, the evolution of the magnetic field is described by a `generalized Ohm's law' that includes the Hall effect and the ambipolar diffusion terms. These terms introduce additional spatial and ...
