  • On the Formation of Bridges and Tails in Interacting Galaxies - II 
    Namboodiri, P. M. S; Kochhar, R. K; Alladin, S. M (Astronomical Society of Indian, 1987-12)
  • Report on the I. A. U. Symposium No. 69 
    Alladin, S. M (Astronomical Society of India, 1974-12)
  • Scattering in a parabolic encounter of a single star with a circular binary 
    Hasan, S. N; Tagare, S. G; Alladin, S. M (Astronomical Society of India, 2000)
    Huang and Valtonen (1987) obtained an analytic expression for the energy transfer in a parabolic encounter of a single star with a circular binary keeping terms of the first order in a/q where a is the radius of the circular ...
  • Stellar Velocity Perturbations in colliding Galaxies II 
    Narasimhan, K. S. V. S; Alladin, S. M (Astronomical Society of India, 1983-09)
    An analytical relationship is obtained between the stellar velocity perturbations and the eccentricity of the galactic orbit, under the impulsive approximation, for a hyperbolic encounter between two spherical galaxies.
  • Tidal disruption and tidal coalescence in binary stellar systems 
    Alladin, S. M; Parthasarathy, M (Royal Astronomical Society, 1978-09)
    Tidal effects in binary stellar systems are considered. The rate of increase of the binding energy of a component and the rate of decrease of the energy of the orbital motion of the binary are estimated under the simplifying ...
  • Tidal disruption in colliding galaxies 
    Narasimhan, K. S. V. S; Alladin, S. M (Astronomical Society of India, 1982-09)
    Distruptive effects in colliding galaxies due to their mutual tidal interaction are compared under the impulsive approximation. If M1 and M2 are the masses and Rho1 and Rho2 the densities of the two galaxies, M2 suffers ...
  • Tidal disruption model for the interacting pair of galaxies VV 117 (NGC 2444/45) 
    Narasimhan, K. S. V. S; Namboodiri, P. M. S; Alladin, S. M (Springer, 2003-09)
    A series of N-body simulations have been performed to interpret the interacting pair of galaxies VV 117 (NGC 2444/45). The galaxies have been modelled assuming a mass ratio two. The simulations use various values for the ...
  • A Tidal model for the inetracting pair of galaxies VV 117 
    Narasimhan, K. S. V. S; Alladin, S. M (Astronomical Society of India, 1985-12)
    Limber`s (1965) tidal model for the interacting pair of galaxies VV 117 ( = Arp 143 = NGC 2444-45) is improved upon in the light of subsequent H I observations. It is proposed that the spiral Sc component is being disrupted ...
  • Tidal transfer of energy and angular momentum to spheroidal galaxies 
    Som Sunder, G; Kochhar, R. K; Alladin, S. M (Royal Astronomical Society, 1990-06)
    The tidal transfer of energy and angular momentum to a spheriodal test galaxy is studied using tensor virial equations within the framework of impulse approximation. The tidally introduced angular momentum is always along ...
  • Tidally affected galaxies modelled as Maclaurin spheroids 
    Som Sunder, G; Kochhar, R. K; Alladin, S. M (Astronomical Society of Indian, 1989-12)
    Tensor virial equations and impulse approximation are used to study the tidal transfer of energy and angular momentum to a test galaxy, modeled as a Maclaurin spheroid. It is shown that the fractional increase in kinetic ...
