    Many B-type stars exhibit two phenomena that are symbolized Be and B[e]. The former refers to presence of a circumstellar gaseous disk without significant circumstellar dust, while the latter have dust. Although neither ...
  • Binarity and Accretion in AGB Stars: HST/STIS Observations of UV Flickering in Y Gem 
    Sahai, R; Contreras, C. S; Mangan, A. S; Sanz-Forcada, J; Muthumariappan, C; Claussen, M. J (IOP Publishing, 2018-06-20)
    Binarity is believed to dramatically affect the history and geometry of mass loss in AGB and post-AGB stars, but observational evidence of binarity is sorely lacking. As part of a project to search for hot binary companions ...
  • Binary pulsar PSR B1913+16 constrains the electron-proton charge asymmetry 
    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 ...
  • Binary star detection in the open cluster King 1 field 
    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 ...
  • Birth and early evolution of a planetary nebula 
    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 ...
  • Birthrate of Planetary Nebulae 
    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 ...
  • Bisymmetric pupil modification deconvolution strategy for differential optical transfer function (dOTF) wavefront sensing 
    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 ...
  • Black hole demographics from TDE modeling 
    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 ...
  • Black hole entropy: some skin deep subtleties sans strings 
    Sivaram, C (Anita Publications, 2004)
  • Black Hole Hawking Radiation May Never Be Observed! 
    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. ...
  • Black hole shadow and acceleration bounds for spherically symmetric space times 
    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 ...
  • The Black Hole-Galaxy Connection: Interplay between Feedback, Obscuration, and Host Galaxy Substructure 
    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 ...
  • Black Holes and Rotation 
    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 ...

  • Black holes are in sight - Nobel in physics 2020 
    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 ...
  • Black holes in nonflat backgrounds: The Schwarzschild black hole in the Einstein universe 
    Nayak, R. K; MacCallum, M. A; Vishveshwara, C. V (The American Physical Society, 2001-01)
    As an example of a black hole in a non-flat background a composite static spacetime is constructed. It comprises a vacuum Schwarzschild spacetime for the interior of the black hole across whose horizon it is matched onto ...
  • Black Holes in Our Universe: Do they Inch up the Mass Ladder? 
    Shastri, P (Indian Academy of Sciences, 2017-03)
    Current technologies have enabled glimpses at the many facets of black holes, which we know to be plentiful in our cosmos. A panoramic view of the evidence for them is presented here across the large range of masses that ...
  • Blanketing sporadic E layer near the magnetic equator
