  • Sengupta, S (Elsevier, 2000-07)
    A binary stellar system loses its orbital rotational energy by the emission of gravity wave. If there exists a charge asymmetry between electron and proton then the system would also lose its orbital rotational energy due ...
  • Subramaniam, A; Gorti, U; Sagar, R; Bhatt, H. C (Astronomical Society of India, 2000)
  • Saleh, P. R; Hazarika, D; Dar, A. A; Parihar, P. S; Saikia, E (IOP Publishing, 2020-03)
    A rarely studied open cluster, King 1 is observed using the 1.3-m telescope equipped with a 2k × 4k CCD at Vainu Bappu Observatory, India. We analyze the photometric data obtained from CCD observations in both B and V ...
  • Narlikar, J. V (Astronomical Society of India, 1990)
    Conceptual and observational issues involved in using binary stars for tests of theories of gravity are discussed. Individual binary star systems that offer the most suitable opportunities for such testing are examined, ...
  • Stratton, F.J.M (The Royal Society, 1957)
  • Gupta, S. K; Mathew, S. K (Astronomical Society of India, 1998)
  • Bobrowsky, M; Sahu, K. C; Parthasarathy, M; García-Lario, P (Nature Publishing Group, 1998-04)
    The final expulsion of gas by a star as it forms a planetary nebula - the ionized shell of gas often observed surrounding a young white dwarf - is one of the most poorly understood stages of stellar evolution,. Such nebulae ...
  • Parthasarathy, M (Astronomical Society of India, 2000)
    Birth and early evolution of planetary nebulae is described. The study of the young planetary nebula Hen 1357 (Stingray Nebula) with HST is discussed. The observed characteristics of few interesting PPNe and PNe are ...
  • Mallik, D. C. V (International Astronomical Union, 1983)
    The electron density, temperature and ion abundances in the nebulae surrounding the two WC 10 stars CPD-56 deg 8032 and He2-113 have been estimated. In CPD-56 deg 8032 sulphur, nitrogen and oxygen seem to have solar ...
  • Elsworth, Y (Astronomical Society of India, 1996)
    The Birmingham Solar Oscillations group runs the so-called BiSON network. As the network has been operational since 1981 we have the great advantage of long, well-filled, historical datasets. These data have been put to ...
  • Martinez, P; Radhika, D (EDP Sciences, 2023-12)
    Context. The differential optical transfer function (dOTF) is a model-independent image-based wavefront sensor for measuring the complex pupil field (phase and amplitude). This method is particularly suitable for compensating ...
  • Mageshwaran, T; Mangalam, A (Cambridge University Press, 2018-05)
    The occurence rate of tidal disruption events (TDEs) by survey missions depend on the black hole mass function of the galaxies, properties of the stellar cusp and mass of the central black hole. Using a power law density ...
  • Sivaram, C (Anita Publications, 2004)
  • Sivaram, C (Springer, 2001-02)
    Thermal Hawking emission from black holes is a remarkable consequence of the unification of quantum physics and gravitation. Black holes of a few solar masses are the only ones which can form in the present universe. ...
  • Kajol, P; Kolekar, Sanved (American Physical Society, 2023-11-15)
    We explore an interesting connection between black hole shadow parameters and the acceleration bounds for radial linear uniformly accelerated (LUA) trajectories in static spherically symmetric black hole spacetime geometries ...
  • Juneau, Stephanie; Goulding, Andy D; Banfield, Julie; Bianchi, Stefano; Duc, Pierre-Alain; Ho, I. -Ting; Dopita, Michael A; Scharwächter, Julia; Bauer, Franz E; Groves, Brent; Alexander, David M; Davies, Rebecca L; Elbaz, David; Freeland, Emily; Hampton, Elise; Kewley, Lisa J; Nikutta, Robert; Shastri, Prajval; Shu, Xinwen; Vogt, Frederic P. A; Wang, Tao; Wong, O. Ivy; Woo, Jong-Hak (American Astronomical Society, 2022-02-01)
    There is growing evidence for physical influence between supermassive black holes and their host galaxies. We present a case study of the nearby galaxy NGC 7582, for which we find evidence that galactic substructure plays ...
  • Kapoor, R. C (Astronomical Society of India, 1976-03)
  • Vishveshwara, C. V (Indian Academy of Sciences, 1999-12)
    In this article, we first consider briefly the basic properties of the non –rotating schwarzschild black hole and the rotating Kerr Black hole rotational effects are then described in static and stationary spacetimes with ...
  • Sivaram, C (South Asian Publisher, 2009-03)
    The relevant physics for the possible formation of black holes in the LHC is discussed.
  • Anupama, G. C (Indian Physics Association, 2020-10)
    The Nobel Prize in Physics 2020 has been awarded to three scientists. One half of the prize was awarded to Roger Penrose and the other half was jointly awarded to Reinhard Genzel and Andrea Ghez. Penrose’s discovery of ...
