  • The stellar parametrization using Artificial Neural Network 
    Giridhar, S; Goswami, A; Kunder, A; Muneer, S; Selvakumar, G (Astronomical Society of India, 2012)
    An update on recent methods for automated stellar parametrization is given. We present preliminary results of the ongoing program for rapid parametrization of field stars using medium resolution spectra obtained using Vainu ...
  • Classification of Nova Spectra 
    Anupama, G. C (Astronomical Society of India, 2012)
    The evolution of the optical spectrum of a nova outburst is described. The classification schemes used to classify novae based on the outburst spectral features and their evolution are discussed.
  • Classical Be stars in our Galaxy and the Magellanic Clouds 
    Subramaniam, A; Mathew, B; Paul, K. T; Mennickent, R. E; Sabogal, B (Astronomical Society of India, 2012)
    We summarise our studies of the Classical Be (CBe) stars in our Galaxy and in the Large and Small Magellanic Clouds. We studied their properties using optical and near-IR photometry and optical spectroscopy. The CBe stars ...
  • Spectroscopic charaterization of FHLC stars from the Hamburg/ESO survey and a newly found HdC star 
    Goswami, A (Astronomical Society of India, 2012)
    The sample of candidate faint high latitude carbon (FHLC) stars chosen from the Hamburg/ESO survey is a potential source to search for objects of rare types. From medium resolution spectral analyses of about 250 objects ...
  • The Diffuse Ultraviolet Foreground 
    Murthy, J (Springer, 2014-01)
    Ultraviolet observations from low Earth orbit (LEO) have to deal with a foreground comprised of airglow and zodiacal light which depend on the look direction and on the date and time of the observation. We have used all-sky ...

  • Study of Young Stellar Objects and Associated Filamentary Structures in the Inner Galaxy 
    Bhavya, B; Subramaniam, A; Kuriakose, V. C (Oxford University Press on behalf of the Royal Astronomical Society, 2013-10-11)
    Young stellar objects in the inner Galactic region 10° < l < 15° and −1° < b < 1° were studied using GLIMPSE images and the GLIMPSE data catalogue. A total of 1107 Class I and 1566 Class II sources were identified in this ...
  • Improved characterization of intranight optical variability of prominent AGN classes 
    Goyal, A; Gopal-Krishna; Wiita, P. J; Stalin, C. S; Sagar, R (Oxford University Press on behalf of the Royal Astronomical Society, 2013-10-21)
    The incidence of intranight optical variability (INOV) is known to differ significantly among different classes of powerful active galactic nuclei (AGN). A number of statistical methods have been employed in the literature ...
  • Beobachtungen des Kometen 1910 a 
    Smith, C. M (Wiley, 1910-03)
  • Indications of twist in the Epsilon rings of Uranus 
    Vasundhara, R; Bhattacharyya, J. C (Centre national D Etudes Spatiales, 1982)
    The possibility of the Uranus epsilon ring having a structure consisting of a twisted bundle of narrow lanes of condensed material similar to that of Saturn's F ring was examined by cross correlation of a pair of light ...
  • Kinematics and Excitation of the Nuclear Spiral in the Active Galaxy Arp 102B 
    Couto, G. S; Storchi-Bergmann, T; Axon, D. J; Robinson, A; Kharb, P; Riffel, R. A (Oxford University Press on behalf of the Royal Astronomical Society, 2013-11-11)
    We present a two-dimensional analysis of the gaseous excitation and kinematics of the inner 2.5 × 1.7 kpc2 of the low-ionization nuclear emission-line region (LINER)/Seyfert 1 galaxy Arp 102B, from optical spectra obtained ...
  • First Steps with CO5BOLD Using HLLMHD and PP Reconstruction. 
    Steiner, O; Rajaguru, S. P; Vigeesh, G; Steffen, M; Schaffenberger, W; Freytag, B (Societa Astronomica Italiana, 2013)
    We report on first experiences with real-life applications using the MHD-module of CO5BOLD together with the piecewise parabolic reconstruction scheme and present preliminary results of stellar magnetic models with Teff = ...
  • Carbon Abundances From SDSS Globular Clusters: Exploring the Origin in the Large Spread in [C/Fe] 
    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. ...
  • Low-frequency Observations of Transient Quasi-periodic Radio Emission from the Solar Atmosphere 
    Sasikumar Raja, K; Ramesh, R (IOP Publishing, 2013-09-20)
    We report low-frequency observations of quasi-periodic, circularly polarized, harmonic type III radio bursts whose associated sunspot active regions were located close to the solar limb. The measured periodicity of the ...
  • Intensity profile of light scattered from a rough surface 
    Chatterjee, S; Vani, V. C; Banyal, R. K (Optical Society of America, 2013-08-20)
    We present in this paper, approximate analytical expressions for the intensity of light scattered by a rough surface, whose elevation ξ x; y in the z-direction is a zero mean stationary Gaussian random variable. With ...
  • Seventeen 2 Micron All Sky Survey (2MASS) Hypervelocity Stars (HVS) from Gaia DR3 
    Parthasarathy, M (American Astronomical Society, 2024-01)
    As part of an ongoing search for hypervelocity stars I found seventeen two micron all sky survey sources with Gaia G magnitudes less than 16.0 and radial velocities less than -600 km s-1. All these stars are brighter in ...
