  • Meera Iyer (Deccan Herald, 2011-05-24)
    HERITAGE The stone alignment at Vibhutihalli in Yadgir district was used to track annual events like solstices and equinoxes. Meera Iyer visits the site and marvels at the ingenuity of our ancestors.
  • Sidharth, B. G (Astronomical Society of India, 1998)
    The Rig Veda described both a solar and a luni-solar calendrical scheme. Once the precision of Rig Vedic astronomy is recognized, the Great Cosmis Cycles of ancient India can be interpreted meaningfully.
  • Shantikumar, N. S; Bagare, S. P; Rajendra, B. S; Campanelli, M; Khatri, P; Dorjey, N (Elsevier B.V, 2014-06-15)
    The present work was carried out to check the performance of a Prede Sky radiometer and the stability of the solar calibration constant (F0s) at two high altitude pristine stations, Hanle and Merak in Ladakh region during ...
  • Leahy, Denis; Postma, J; Hutchings, J. B; Tandon, S. N (Cambridge University Press, 2018-08)
    The UVIT ultraviolet and visual band detectors and electronics for the ASTROSAT observatory were calibrated in the vacuum laboratory at the University of Calgary. This work was supported by the Canadian Space Agengy and ...
  • Sivaraman, K. R; Bagare, S. P; Gupta, S. S; Kariyappa, R (Springer, 1987-07)
    The intimate association between the surface magnetic fields and the Ca II K-line emission known to exist on the Sun, holds a promise for using this property to detect the presence of global magnetic fields on Sun-like ...
  • Antia, H. M; Chitre, S. M (Astronomical Society of India, 1999)
  • Kataria, Sandeep Kumar; Mousumi Das (Cambridge University Press, 2019-06)
    One of the major and widely known small scale problem with the Lambda CDM model of cosmology is the “core-cusp” problem. In this study we investigate whether this problem can be resolved using bar instabilities. We see ...
  • Venkatakrishnan, P (Astronomical Society of the Pacific, 1994)
  • Srivastava, N (Astronomical Society of India, 2002-09)
    Coronal mass ejections or CMEs are well known as the drivers of enhanced interplanetary and geomagnetic activity. They are large expulsions of material from the Sun, which travel into the interplanetary (IP) medium. ...
  • Gaur, V. P; Joshi, G. C; Pande, M. C (Astronomical Society of India, 1992)
    The equivalent widths of the P and R branch lines of the fundamental vibration-rotation band arising from the ground state of HeH(+) have been calculated in a chosen photospheric model. The resulting equivalent widths ...
  • Nepomnyashchikh, A; Mandal, Sudip; Banerjee, D; Kitchatinov, Leonid (EDP Sciences, 2019-05)
    Context. The hemispheric asymmetry of sunspot activity observed possesses a regular component varying on a timescale of several solar cycles whose origin and properties are currently debated. Aims This paper addresses ...
  • Rubinur, K; Mousumi Das; Kharb, P; Honey, M (Oxford University Press on behalf of the Royal Astronomical Society, 2017-03)
    We present high-resolution radio continuum observations with the Karl G. Jansky very large array at 6, 8.5, 11.5 and 15 GHz of the double-peaked emission-line galaxy 2MASXJ12032061+1319316. The radio emission has a prominent ...
  • Sreekanth Reddy, V (Indian Institute of Astrophysics, 2014-08)
    Edge sensors are high precision displacement sensors used in segmented mirror telescope to measure relative displacement between two mirror segments. An edge sensor based on parallel plate capacitor is being used in Keck ...
  • Bhatt, H. C (European Southern Observatory, 1989-04)
    Field stars can be captured by massive interstellar clouds. Stars encounter interstellar clouds with relative velocities that have a distribution. Close encounters in which stars enter a cloud with relative velocities less ...
  • Fiorenza, S. L; Sivarani, T; Susmitha, A; Lee, Y. S; Beers, T. C (Societa Astronomica Italiana, 2013)
    Globular clusters were once thought to be chemically homogeneous systems with a single stellar population. However, recent results suggest the presence of more than one stellar population among most all globular clusters. ...
  • Tripathi, B. M; Pande, M. C; Sinha, K (Astronomical Society of India, 1982-06)
    Equivalent widths for a new lines of the first overtone band of carbon monoxide have been calculated in the solar infrared spectrum for five facular and two photospheric models. The calculations show a decrease in equilavent ...
  • Lee, Y. S; Beers, T. C; Masseron, T; Plez, B; Rockosi, C. M; Sobeck, J; Yanny, B; Lucatello, S; Sivarani, T; Placco, V. M; Carollo, D (IOP Publishing, 2013-11)
    We describe a method for the determination of stellar [C/Fe] abundance ratios using low-resolution (R = 2000) stellar spectra from the Sloan Digital Sky Survey (SDSS) and its Galactic sub-survey, the Sloan Extension for ...
  • Carollo, D; Beers, T. C; Bovy, Jo; Sivarani, T; Norris, J. E; Freeman, K. C; Aoki, W; Lee, Young Sun; Kennedy, C. R (IOP Publishing, 2012-01-10)
    Carbon-enhanced metal-poor (CEMP) stars in the halo components of the Milky Way are explored, based on accurate determinations of the carbon-to-iron ([C/Fe]) abundance ratios and kinematic quantities for over 30,000 ...
  • Ramachandra, B. S (Springer, 2009-12)
    The existence of the Carter constant in the Vaidya–Einstein–Kerr (VEK) spacetime and its relation to the Petrov type is investigated. This spacetime is an example of a black hole in an asymptotically non-flat background. ...
  • Beers, T. C; Carollo, D; Ivezic, Z; An, D; Chiba, M; Norris, J. E; Freeman, K. C; Lee, Young Sun; Munn, J. F; Re Fiorentin, P; Sivarani, T; Wilhelm, R; Yanny, B; York, D. G (IOP Publishing, 2012-02-10)
    Carollo et al. have recently resolved the stellar population of the Milky Way halo into at least two distinct components, an inner halo and an outer halo. This result has been criticized by Schönrich et al., who claim that ...
