  • Gopala Rao, U. V (D. Reidel Publishing Company, 1970-10)
    Homologous characteristics of radio bursts at 3000 MHz and associated optical flares are studied. It is found that flares associated with homologous radio bursts are also homologous optically.

  • Birdie, C (Astronomical Society of the Pacific, 2010)
    A special session was held during the LISA VI conference to felicitate veteran librarians and to highlight their achievements. A list of honorees is given.

  • Khan, A; Saha, L. M; Prasad Sarma, T (Astronomical Society of India, 1999)
    Hori's method of solving coupled non-linear differential equations has been used to solve restricted problem of three bodies and non-resonance case has been discussed. For a certain set of values of the parameters, the ...
  • Rani, S; Pandey, G; Subramaniam, A; Sahu, S; Kameswara Rao, N (Indian Academy of Sciences, 2020-12)
    We present the results obtained from the UV photometry of the globular cluster NGC 1261 using far-UV (FUV) and near-UV (NUV) images acquired with the Ultraviolet Imaging Telescope (UVIT) on-board the AstroSat satellite. ...

  • Jain, K; Tripathy, S. C; Ravindra, B; Komm, R; Hill, F (IOP Publishing, 2016-01)
    Continuous high-cadence and high spatial resolution Dopplergrams allow us to study subsurface dynamics that may be further extended to explore precursors of visible solar activity on the surface. Since the p -mode ...
  • Pravabati, C; Park, C; Yogendran, K. P; van de Weygaert, R (IOP Publishing, 2012-08-20)
    We introduce the numbers of hot and cold spots, n/subh/ and n/subc/, of excursion sets of the cosmic microwave background (CMB) temperature anisotropy maps as statistical observables that can discriminate different ...
  • Subramaniam, A; Sindhu, N; Tandon, S. N; Kameswara Rao, N; Postma, J; Cote, Patrick; Hutchings, J. B; Ghosh, S. K; George, K; Girish, V (IOP Publishing, 2016-12-20)
    We present early results from the Ultra-Violet Imaging Telescope (UVIT) on board the ASTROSAT observatory. We report the discovery of a hot companion associated with one of the blue straggler stars (BSSs) in the old open ...
  • Parthasarathy, M; Gauba, G; Fujii, T; Nakada, Y (Kluwer Academic Publishers, 2001-08)
    From the study of IRAS sources with far-IR colors similar to planetary nebulae (PNe), several proto-planetary nebulae with hot (OB) post-AGB central stars have been detected. These stars form an evolutionary link between ...
  • Kameswara Rao, N; Giridhar, S; Lambert, D. L (The European Southern Observatory, 1993-12)
    High resolution spectra in the red region of the hot R CrB star DY Cen show the following characteristics: a strong absorption line spectrum dominated by lines of C II, N II, and Ne I inverse P-Cygni type profiles of some ...
  • Balona, L. A; Engelbrecht, C. A; Joshi, Y. C; Joshi, S; Sharma, K; Semenko, E; Pandey, G; Chakradhari, N. K; Mkrtichian, D; Hema, B. P; Nemec, J. M (Oxford University Press on behalf of the Royal Astronomical Society, 2016-09)
    The hot γ Doradus stars have multiple low frequencies characteristic of γ Dor or SPB variables, but are located between the red edge of the SPB and the blue edge of the γ Dor instability strips where all low-frequency ...

  • Kapoor, R. C (Bennett. Coleman & Co., Ltd., 1977-05)
  • Das, S. R (Astronomical Society of India, 1996)
  • Boriero, Daniel; Das, Subinoy; Wong, Yvonne Y. Y (IOP Publishing, 2015-06)
    We explore a chameleon type of interacting dark matter-dark energy scenario in which a scalar field adiabatically traces the minimum of an eff ective potential sourced by the dark matter density. We discuss extensively ...
  • Borde, A (Astronomical Society of India, 1997)
    It is often stated that topology change is impossible in classical general relativity. In particular, it appears to be widely believed that the pleasure of topology change comes at a fixed price: topology – changing space ...
  • Sarkar, A; Das, Subinoy; Sethi, Shiv K (IOP Publishing, 2015-03)
    We put constraints on the epoch of dark matter formation for a class of non-WIMP (Weakly Interacting Massive Particle) dark matter candidates. These models allow a fraction of Cold Dark Matter (CDM) to be formed between ...
