  • 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 ...
  • Uranus and the Invisible Planets 
    Kochhar, R. K (Royal Astronomical Society, 1987-12)
