  • On the points of bifurcation along the sequence of rotating axisymmetric masses with magnetic fields 
    Kochhar, R. K (Indian Academy of Sciences, 1975-11)
    It is shown that the points of bifurcation belonging to the third harmonics along the sequence of Maclaurin spheroids viewed from an inertial frame are distinct from the corresponding points along the Maclaurin sequence ...
  • On the post-Newtonian effects in the millisecond pulsar 1937 + 214 
    Kochhar, R. K; Sivaram, C (Indian Academy of Sciences, 1984-04)
  • On the relationship between pulsars and supernova remnants 
    Kochhar, R. K (Indian Academy of Sciences, 1981-03)
    We propose that single stars in the mass range 4–6·5M ⊙, that explode as Supernovae of Type I, are totally disrupted by the explosion and form shell-type remnants. More massive single stars which explode as Supernovae of ...
  • On the slow-down of the millisecond pulsar PSR 1937 + 214 
    Sivaram, C; Kochhar, R. K (Springer, 1984-01)
    There are indications that less than 10/sup-3 of the spin-down energy of the millisecond pulsar PSR 1937+214 emerges as electromagnetic radiation. The implications of this result are discussed. The surface magnetic field ...
  • On the stability of helical velocity and magnetic fields 
    Kochhar, R. K (D. Reidel Publishing Company, 1978-05)
    In this paper we study the stability of an infinitely conducting, incompressible, inviscid infinite cylinder with non-parallel helical velocity and magnetic field. It is shown that the system is stable if the energy in the ...
  • On the tidal disruption of a spherical galaxy 
    Namboodiri, P. M. S; Kochhar, R. K (Blackwell Publishing, 1991-12)
    The disruption of a satellite galaxy as it undergoes collision with a massive perturber is investigated by numerical simulations. The models are restricted by a constant pericentric distance. The disruption of the satellite ...
  • Poor science, poor journals 
    Kochhar, R. K (Indian Academy of Sciences, 1990-08-25)
  • R. LI. Jones-C. V. Raman's physics professor at presidency college Madras 
    Kochhar, R. K (Indian Academy of Sciences, 1990-01-10)
  • Rahu in the Burmese Tradition 
    Kochhar, R. K (Royal Astronomical Society, 1990-06)
  • Roche instability in binary stellar systems 
    Namboodiri, P. M. S; Kochhar, R. K (Nova Science Publishers Inc, 1993)
  • Runaway stars as witnesses to supernova explosions 
    Kochhar, R. K (Nature Publishing Group, 1978-02)
    A hypothesis is proposed according to which single runaway stars are released from close binaries in which the companion star explodes as a carbon detonation supernova and is totally disrupted. From the stars which can ...
  • Science in british India 2. Indian response 
    Kochhar, R. K (Indian Academy of Sciences, 1993-01-10)
    The first part of this article sets up a nested three-stage model for the advent and growth of modern science in India. We have already discussed the first stage, the colonial-tool stage, where science was used by the ...
  • Science in British India. I. Colonial tool 
    Kochhar, R. K (Indian Academy of Science, 1992-12-10)
  • The secular instability of slightly viscous magnetic Maclaurin spheroids 
    Kochhar, R. K; Sivaram, C (Springer, 1983-10)
    The properties of rotating bodies close to their stability limits are investigated analytically. A homogeneous self-gravitating mass rotating about the 3-axis and having both a small amount of viscosity and a general ...
  • Shipbuilding at Bombay 
    Kochhar, R. K (Indian Academy of Sciences, 1994-06)
  • Spin angular momentum of tidally affected galaxies 
    Namboodiri, P. M. S; Kochhar, R. K (Royal Astronomical Society, 1991-06)
    Numerical experiments have been performed to study the transfer of angular momentum to an initially non-rotating spherical galaxy as it undergoes a collision with a point mass perturber moving in a relative orbit of constant ...
  • Supernovae in early-type galaxies 
    Kochhar, R. K (Kluwer Academic Publishers, 1989-07)
    It is argued that all SNI come from short-lived stars and do not occur in a typical, isolationist, gas-free early-type galaxy. SNI occur only in those galaxies which accrete gas and form stars. SN properties of E/SOs are, ...
  • Tidal change in the energy of a spherical galaxy 
    Namboodiri, P. M. S; Kochhar, R. K (Royal Astronomical Society, 1990-03)
    Tidal effects of a massive perturber on a satellite galaxy have been studied by numerical simulations. The model consists of a spherical satellite galaxy and a point-mass perturber and the encounter is non-penetrating. A ...
  • 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 ...
