    We report photometric observations for comet C/2012 S1 (ISON) obtained during the time period immediately after discovery (r = 6.28 AU) until it moved into solar conjunction in mid-2013 June using the UH2.2 m, and Gemini ...
  • The Hamburg/ESO R-process Enhanced Star survey (HERES) VIII. The r+s star HE 1405 0822 
    Cui, W. Y; Sivarani, T; Christlieb, N (EDP Sciences, 2013-10)
    Aims. The aim of this study is a detailed abundance analysis of the newly discovered r-rich star HE 1405−0822, which has [Fe/H] = −2.40. This star shows enhancements of both r- and s-elements, [Ba/Fe] = + 1.95 and [Eu/Fe] ...
  • Spectroscopy of Scorpio-Centaurus association 
    Rajamohan, R (Centre of Advanced Study in Astronomy, Osmania University, 1973)
    Rotational velocities and intensities of hydrogen and helium lines for over 40 members of the Scorpio Centaurus association are presented. From the measured equivalent width of H alpha and H delta some evidence is found ...
  • The spectrum of gamma velorum 
    Rajamohan, R (Centre of Advanced Study in Astronomy, Osmania University, 1973)
    From a measurement of the equivalent width of H alpha in the star gamma 1 Velorum, it is found that My (gamma1 Vel)=-3.1. Assummg gamma 1 and 2 Velorum are at the same distance, a distance modulus of 7.4 magnitudes for ...
  • Properties of Newly Formed Dust Grains in the Luminous Type IIn Supernova 2010jl 
    Maeda, K; Nozawa, T; Sahu, D. K; Minowa, Y; Motohara, K; Ueno, I; Folatelli, G; Pyo, T. S; Kitagawa, Y; Kawabata, K. S; Anupama, G. C; Kozasa, T; Moriya, T. J; Yamanaka, M; Nomoto, K; Bersten, M; Quimby, R; Iye, M (IOP Publishing, 2013-10-10)
    Supernovae (SNe) have been proposed to be the main production sites of dust grains in the universe. However, our knowledge of their importance to dust production is limited by observationally poor constraints on the nature ...
  • Stellar streams in the Galactic thick disk: preliminary results 
    Ramya, P; Reddy, B. E (Astronomical Society of India, 2012)
    Here we report preliminary results of our study of chemical tagging of member stars of two Galactic stellar streams. Both the streams, kinematically belong to the thick disk component of the Galaxy. We analysed high ...
  • Stellar libraries as used in ISM modelling 
    Murthy, J (Astronomical Society of India, 2012)
    I present the use of stellar libraries in interstellar medium work. Stars are used as background sources against which interstellar absorption lines are observed and their modeling is necessary in order to set the baseline ...
  • 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 ...
