  • Mageshwaran, T (Indian Institute of Astrophysics, 2017-11)
    A nearly self contained and detailed introduction to TDE physics with novel aspects and a summary of observations is provided. We have constructed a dynamical model of tidal disruption events (TDEs) that includes physical ...
  • Regan, Jeanette; Koch, M. C; Gomez, M. E; Louis, C; Corbin, B. G (Astronomical Society of Pacific, 2001)
    Non-commercIal astronomical publications have been freely distributed worldwide to relevant institutIOns for more than a century. Astronomers have considered collaboration a very important aspect of their work and, ...
  • Murty, P. S (D.Reidel Publishing Co.,, 1983-08)
    Identifications of the molecular absorption features in the visible spectrum of the S star Pi Gruis are presented. Moderate dispersion spectrum of π/sup1 Gru covering the region 5800-7300 Å, demonstrates the presence of a ...
  • Bahadur, Rana (Astronomical Society of India, 1911-07)
  • Kashyap, V; Drake, J. J (Astronomical Society of India, 2000)
    PINTofALE was developed to analyze spectroscopic data from coronal sources in the 1-1500 Å range. It is based on a modular set of IDL tools that interact with an atomic database and with observational data. The tools allow ...
  • Banyal, R. K; Prasad, B. R (Indian Academy of Sciences, 2005-08)
    We present a simple technique for the determination of pixel size and pitch of liquid crystal (LC) based spatial light modulator (SLM). The proposed method is based on optical diffraction from pixelated LC panel that has ...
  • Narasimha, D (Astronomical Society of India, 2004-09)
    The Ooty lens PKS1830-211 is a bright, variable radio source at a redshift of 2.507 consisting of a compact flat spectrum core, associated knot and jet, which are lensed by an intervening spiral galaxy at a redshift of ...
  • Joshi, U. C (Astronomical Society of India, 1982-09)
    Places of formation of 10 nearby classical Cepheids have been computed in a model of our Galaxy which has axisymmetric and spiral-like components. For the axisymmetric components Schmidt's (1965) model is used, and spiral-like ...
  • Sivaram, C (Springer, 1986-11)
    Any attempt at unification of gravity with quantum physics inevitably leads to the Planck length, usually interpreted as defining the distance scale at which quantum corrections to general relativity are expected to become ...
  • Sivaram, C; Arun, K; Rebecca, L (Springer, 2020-01)
    The standard model of cosmology, although very successful, has problems with the very initial phase, such as the existence of a singularity when the density and curvature becomes infinite. In this work we propose a possible ...
  • Bhatt, H. C (Astronomical Society of India, 1999)
    Recent discoveries of substellar and planetary-mass objects in orbit around other stars represent the most remarkable progress achieved in the search for extrasolar planetary systems. The evidence for their existence is ...
  • Venkatavaradan, V. S (Astronomical Society of India, 1976-09)
  • Sivaram, C; Arun, K; Kiren, O. V (Springer, 2016-07)
    Here we propose the possibility that the recently postulated Neptune-sized planet with an orbital period of 15,000 years could be a gravitationally condensed dark matter (DM) object. The observed mass of Planet Nine fits ...
  • Gaur, V. K (Springer Netherlands, 2008)
    The article begins with a reference to the first rational approaches to explaining the earth’s magnetic field notably Elsasser’s application of magneto-hydrodynamics, followed by brief outlines of the characteristics of ...
  • Sivaram, C (D. Reidel Publishing Co., 1987-02)
    Recent improvements in the quantitative estimates of the observed heat flow from planetary objects of the solar system may be used to put rather stringent limits on any background monopole flux. The axion flux from the ...
  • Mallik, D. C. V (Astronomical Society of India, 1982-06)
    Recent research on planetary nebulae is reviewed, with special emphasis on ultraviolet and infrared observations. Various distance scales and statistics based on them are discussed and the emperical mass-radius relation ...
  • Mallik, D. C. V (Astronomical Society of Australia, 1991)
    The review describes some of the progress made in observations and their interpretation, particularly in the context of the evolution of the nebulae and the central stars. It includes a discussion on the improved determinations ...
  • Mallik, D. C. V (Geneva Observatory, 1978)
    The extent of nitrogen enrichment of the interstellar gas by planetary-nebula formation is evaluated, and the nitrogen and oxygen abundance gradients in the disk of the Galaxy are derived on the basis of a simple model for ...
  • Kameswara Rao, N; De Marco, O; Sriram, K; Murthy, J; Ray, A; Sutaria, F. K; Mohan, Rekhesh (EDP Sciences, 2018-12)
    The high excitation planetary nebula, NGC 6302, has been imaged in two far-ultraviolet (FUV) filters, F169M (Sapphire; λeff: 1608 Å)and F172M (Silica; λeff: 1717 Å) and two near-UV (NUV) filters, N219M (B15; λeff: 2196 Å) ...
  • Kameswara Rao, N; Sutaria, F; Murthy, J; Ray, A; Pandey, G (Indian Academy of Sciences, 2021-10)
    The spectral region between 1250–3000 A contains important spectral lines to understand the ˚ morphological structures and evolution of planetary nebulae. This is the region sampled by UVIT through various filter bands ...
