  • Sarma, R; Pathak, A; Pradhan, A. C; Murthy, J; Sarma, J. K (Elsevier B.V, 2014-03-15)
    We have used Far Ultraviolet Spectroscopic Explorer (FUSE) observations of the Large Magellanic Cloud (LMC) to determine the O vi column densities in the Milky Way (MW) towards 6 LMC lines of sight. The mean column density ...
  • Shastri, P; Murthy, J; Whittle, Mark; Wills, B. J (The American Astronomical Society, 2006-07-20)
    We present far-ultraviolet spectra of the Seyfert 2 galaxy Mrk 533 obtained with FUSE. These spectra show narrow asymmetrical O VI λλ1032,1038 emission lines with stronger wings shortward of the peak wavelength, but the ...
  • Kennedy, C. R; Sivarani, T; Beers, T. C; Lee, Y. S; Placco, V. M; Rossi, S; Christlieb, N; Herwig, F; Plez, B (IOP Publishing, 2011-03)
    We report on oxygen abundances determined from medium-resolution near-infrared spectroscopy for a sample of 57 carbon-enhanced metal-poor (CEMP) stars selected from the Hamburg/ESO Survey. The majority of our program stars ...
  • The Editor (Nature Publishing Group, 1922-11)
  • Bhattacharyya, J. C (Royal Astronomical Society, 1983-03)
  • Eddington, A. S (Royal Astronomical Society, 1923-02)
  • Naidu, B. N; Srinivasan, R; Muralishankar, S (SPIE-The International Society for Optical Engineering, 1997-10)
    In the recent past both the CCD camera controller hardware and software have witnessed a dynamic change to keep pace with the astronomer's imaging requirements. Conventional data acquisition software is based on menu driven ...
  • Polletta, M; Omont, A; Berta, S; Bergeron, J; Stalin, C. S; Petitjean, P; Giorgetti, M; Trinchieri, G; Srianand, R; McCracken, H. J; Pei, Y; Dannerbauer, H (EDP Sciences, 2008-12)
    Aims. Short phases of coeval powerful starburst and AGN activity during the lifetimes of the most massive galaxies are predicted by various models of galaxy formation and evolution. In spite of their recurrence and high ...
  • Venkatakrishnan, P (Kluwer Academic Publishers, 1996)
    The mechanisms that could possibly heat the corona are briefly reviewed with emphasis on their observability. Observing enhanced wave flux at footpoints of active regions would confirm wave heating. Observation of nonthermal ...
  • Saha, S. K (Indian Association for the Cultivation of Science, 2001)
  • Ghosh, K. K; Apparao, K. M. V; Tarafdar, S. P (American Astronomical Society, 1989-09)
    During routine monitoring of the Be star HR 4123 during the year 1987-1988, a burst of H-alpha emission was observed on May 11, 1987. The increase was observed on May 9 and lasted until June 7, peaking to an equivalent ...
  • Singh, J (Indian Institute of Astrophysics, Bangalore, 1997)
    An experiment to search for short-period oscillations in the solar corona was conducted during the total solar eclipse of 1995 October 24 at Kalpi, India. The intensity in the continuum, centred around 5500 Armsrong and ...
  • Maiti, M; Sengupta, S; Parihar, P. S; Anupama, G. C (University of Chicago Press, 2005-02)
    We report, for the first time, photometric variability of L dwarfs in the R band. Out of three L1 dwarfs (2MASS 1300+19, 2MASS 1439+19, and 2MASS 1658+70) observed, we have detected R-band variability in 2MASS 1300+19 and ...
  • Hiei, K; Inoue, K; Takahashi, N; Fukushima, H (Indian Institute of Astrophysics, Bangalore, 1997)
    K-corona and E-corona were observed at Dundlodh in India. Coronal image, processed by a computer, shows polar plumes in north- and south-pole and streamers at east- and west-limb.
  • Maiti, M (The American Astronomical Society, 2007-04)
    The results of quasi-simultaneous continuous monitoring of six L dwarfs in the R and I bands are presented. A careful analysis of the data shows that the object 2MASSW J0036+1821 is variable in the I and R bands. The ...
  • Singh, M; Misra, K; Sahu, D. K; Dastidar, R; Gangopadhyay, A; Srivastav, S; Anupama, G. C; Bose, S; Lipunov, V; Chakradhari, N. K; Brajesh Kumar; Pandey, S. B; Gorbovskoy, E; Balanutsa, P (Oxford University Press on behalf of the Royal Astronomical Society, 2019-06)
    MASTER OT J120451.50+265946.6 (M12045), discovered by the MASTER Global Robotic Net, is a Type Ib supernova (SN) that exploded in NGC 4080. We present the BVRI photometric and spectroscopic observations up to ∼250 d since ...
  • Ray, Alak (Indian Institute of Astrophysics, 1988)
    In the approximately one year since the explosion of the Supernova 1987A in the Large Magellanic Cloud, a large amount of work, both observational as well as theoretical, has been undertaken. Stan Woosley, a prolific worker ...
  • Banerjee, D (Cambridge University Press, 2008-05)
    With multi-wavelength observations from ground and space-based instruments it has been possible to detect waves in a number of different wavelengths simultaneously and to, consequently, study their propagation properties. ...
  • Kariyappa, R; Dame, L; Hiremath, K. M (Indian Academy of Sciences, 2006-09)
    We have used a high spatial and temporal resolution of long time sequence of spectra in CaII H-line obtained at the Vacuum Tower Telescope (VTT) of the Sacramento Peak Observatory on a quiet region at the center of the ...
  • Singh, A; Brajesh Kumar; Moriya, Takashi J; Anupama, G. C; Sahu, D. K; Brown, Peter J; Andrews, Jennifer E; Smith, Nathan (IOP Publishing, 2019-09-01)
    The optical and ultraviolet broadband photometric and spectroscopic observations of the Type II supernova (SN) 2016gfy are presented. The V-band light curve (LC) shows a distinct plateau phase with a slope of s2 ∼ 0.12 mag ...
