  • Approaching gravitation by quantum gravity with matter near four dimensions 
    Elizalde, E; Odintsov, S. D; Romeo, A (Astronomical Society of India, 1997)
    The phase structure and infrared (IR) behavior of higher-derivative quantum gravity (QG) near (but below) four dimensions, with a few different matter theories, shows remarkable properties. Models of this sort can be ...
  • An approximate method of computing precision in certain cases 
    Chatwood, A. B (Astronomical Society of India, 1914-04)
  • An approximate superposition method to obtain a planet's orbit 
    Iyer, Abhinav G; Bhatnagar, Siddharth; Vyasanakere, Jayanth P; Murthy, J (IOP Publishing, 2022-01)
    We demonstrate that the deviation produced by one celestial object on the Keplerian orbit of another around the Sun is largely independent of the presence of the remaining ones. Hence, to calculate the net deviation of ...
  • Appulses of faint stars by fragments of Comet Shoemaker-Levy 9 
    Vasundhara, R (Indian Academy of Sciences, 1994-03)
  • Apsidal motion in the binary Delta Orionis 
    Natarajan, V; Rajamohan, R (Kodaikanal Observatory, 1971)
    A velocity curve of the spectroscopic binary 'Delta Orionis' has been obtained from the spectrograms taken at kodaikanal during the years 1968-70. The orbital elements derived are in good agreement with earlier values ...
  • Architect of defence research 
    The Hindu (The Hindu, 2003-05-01)
  • Archiving of electronic journals in physics and astronomy: role of consortia 
    Birdie, C; Sreeharsha, B. G; Pallavi, T. G; Kannur, Mahantesh B (INFLIBNET Centre, 2003)
    Electronic journals unfold their most valuable features when they are inter-linked with other documents, archives and databases. These electronic journals need an archiving system that is based on a global concept. ...
  • ARCO: a program for Automatic Reduction of CCD Observations 
    Distefano, E; Messina, S; Cutispoto, G; Parihar, P. S; Comparato, M; Busá, I; Lanza, A. F; Lanzafame, A. C; Pagano, I; Strassmeier, K. G (EDP Sciences, 2007)
    The huge amount of CCD photometric data collected by robotic telescopes (as for instance the ICE-T telescope to be installed at Dome-C) requires a fully automated approach to the reduction and analysis procedures. To this ...
  • Ardaseer Cursetjee (1808 - 77), the first Indian fellow of the royal society of London 
    Kochhar, R. K (Royal Society Publishing, 1993)
  • Are C60 Molecules Detectable in Circumstellar Shells of R Coronae Borealis Stars? 
    García-Hernández, D. A; Kameswara Rao, N; Lambert, D. L (IOP Publishing, 2011-03-10)
    The hydrogen-poor, helium-rich, and carbon-rich character of the gas around R Coronae Borealis (RCB) stars has been suggested to be a site for formation of C60 molecules. This suggestion is not supported by observations ...
  • Are DY Persei Stars Cooler Cousins of R Coronae Borealis Stars? 
    Bhowmick, A; Pandey, G; Joshi, V; Ashok, N. M (IOP Publishing, 2018-02)
    Are DY Persei Stars Cooler Cousins of R Coronae Borealis Stars? Anirban Bhowmick 1 , Gajendra Pandey 1 , Vishal Joshi 2 , and N. M. Ashok 2 1 Indian Institute of Astrophysics, Koramangala, Bengaluru 560 034, ...
  • Are H 0 and σ 8 Tensions Generic to Present Cosmological Data? 
    Bhattacharyya, Archita; Alam, Ujjaini; Pandey, Kanhaiya L; Das, Subinoy; Pal, Supratik (IOP Publishing, 2019-05-10)
    Yes, for a wide range of cosmological models (ΛCDM, non-interacting wz CDM, wz WDM, or a class of interacting DMDE). Recently there have been attempts to solve the tension between direct measurements of H0 and s8 0m W from ...
  • Are narrow-line seyfert 1 galaxies powered by low-mass black holes? 
    Viswanath, G; Stalin, C. S; Rakshit, S; Kurian, K. S; Ujjwal, K.; Gudennavar, S. B; Kartha, S. S (IOP Publishing, 2020-03)
    Are Narrow-line Seyfert 1 Galaxies Powered by Low-mass Black Holes? Gayathri Viswanath 1 , C. S. Stalin 2 , Suvendu Rakshit 3 , Kshama S. Kurian 2 , K. Ujjwal 1 , Shivappa B. Gudennavar 1 , and Sreeja S. ...
  • Are Nuclear Hot Spots in Galaxies Sites of Sequential Star Formation? 
    Korchagin, V; Kembhavi, A. K; Mayya, Y. D; Prabhu, T. P (The American Astronomical Society, 1995-06)
    We investigate self-regulated propagation of stars formation, which is one of the possible scenarios of stars formation in molecular clouds fragmented into cold dense structures with masses lying near the Jeans limit. ...
  • Are polar faculae generated by a local dynamo? 
    Sivaraman, K. R; Antia, H. M; Chitre, S. M (Springer, 2010)
    Polar faculae (PF) are bright, small-scale structures measuring a few seconds of arc, populating the polar zones at latitudes >50°. They possess magnetic fields ranging from 150 to 1,700 Gauss and largely constitute the ...
  • Are pulsars strange? 
    Kapoor, R. C; Shukre, C. S (Astronomical Society of India, 2001)
    Pulsar radio pulses are made up of the so called core and conal components. A remarkably precise relation for core component widths, found observationally, in effect specifies the size of the polar cap on pulsars. Inclusion ...
  • Are radio pulsars strange stars? 
    Kapoor, R. C; Shukre, C. S (EDP Sciences, 2001-08)
    A remarkably precise observational relation for pulse core component widths of radio pulsars is used to derive stringent limits on pulsar radii, strongly indicating that pulsars are strange stars rather than neutron stars. ...
  • Are there transit timing variations for the exoplanet qatar-1b? 
    Su, Li-Hsin; Jiang, Ing-Guey; Sariya, Devesh P; Lee, Chiao-Yu; Yeh, Li-Chin; Mannaday, Vineet Kumar; Thaku, Parijat; Chand, Swadesh; Shlyapnikov, A. A; Moskvin, V. V; Ignatov, Vladimir; Mkrtichian, David; Griv, Evgeny; Sahu, D. K (IOP Publishing, 2021-03-01)
    Motivated by the unsettled conclusion on whether there are any transit timing variations (TTVs) for the exoplanet Qatar-1b, 10 new transit light curves are presented and a TTV analysis with a baseline of 1400 epochs is ...
