  • Late-type giants with infrared excess. I. Lithium abundances 
    Jasniewicz, G; Parthasarathy, M; de Laverny, P; Thévenin, F (European Southern Observatory, 1999-02)
    de la Reza et al. (1997) suggested that all K giants become Li-rich for a short time. During this period the giants are associated with an expanding thin circumstellar shell supposedly triggered by an abrupt internal mixing ...
  • The latest two GRB detected by Hete-2: GRB 051022 and GRB 051028 
    Castro-Tirado, A. J; McBreen, S; Jelínek, M; Pandey, S. B; Bremer, M; de Ugarte Postigo, A; Gorosabel, J; Guziy, S; Bihain, G; Caballero, J. A; Ferrero, P; de Jong, J; Misra, K; Sahu, D. K (American Institute of Physics, 2006-05)
    We present multiwavelength observations of the latest two GRB detected by Hete-2 in 2005. For GRB 051022, no optical/nIR afterglow has been detected, in spite of the strong gamma-ray emission and the reported X-ray afterglow ...
  • Latitude character and evolution of Gnevyshev gap 
    Pandey, K. K; Hiremath, K. M; Yellaiah, G (Springer, 2017-06)
    The time interval, between two highest peaks of the sunspot maximum, during which activity energy substantially absorbed is called Gnevyshev gap. In this study we focus on mysterious evolution of the Gnevyshev gap by ...
  • Latitude Distribution of Sunspots: Analysis Using Sunspot Data and a Dynamo Model 
    Mandal, Sudip; Karak, B. B; Banerjee, D (2017-12)
    In this paper, we explore the evolution of sunspot latitude distribution and explore its relations with the cycle strength. With the progress of the solar cycle, the distributions in two hemispheres from mid-latitudes ...
  • Latitudinal distribution of soft x ray flares and dispairty in butterfly diagram 
    Pandey, K. K; Yellaiah, G; Hiremath, K. M (Springer, 2015-04)
    We present statistical analysis of about 63000 soft x-ray flare (class ≥C) observed by geostationary operational environmental satellite (GOES) during the period 1976-2008. Class wise occurrence of soft X-ray (SXR) flare ...
  • Leaves from an unwritten diary- S.Chandrashekhar: Reminiscences and reflections

  • Leh: a high altitude site survey observatory 
    Kochhar, R. K (Indian Institute of Astrophysics, Bangalore, 1986-07)
  • Lenses of small angular scales from Jodrell Bank survey 
    Patnaik, A; Narasimha, D (Astronomical Society of India, 1993)
    The Jodrell Bank 5 GHz sky survey provides a complete flux-limited sample of radio sources at latitude greater than 2.5 deg which are brighter than 200 mJy and have a spectrum flatter than 0.5. From the analysis of nearly ...
  • Lenticular and other galaxies 
    Kembhavi, A. K; Barway, Sudhanshu; Ravi Kumar, C. D (Astronomical Society of India, 2005-06)
    We describe in this paper the surface photometry of a set of lenticular galaxies. We then consider important correlations between morphological parameters of the bulges of lenticulars and other types of galaxies
  • Leo Goldberg, Astronomer, Dies 
    The New York Times (The New York Times, 1987-11-03)
  • Lepto-hadronic Interpretation of 2021 RS Ophiuchi Nova Outburst 
    De Sarkar, Agnibha; Nayana, A. J; Roy, Nirupam; Razzaque, Soebur; Anupama, G. C (American Astronomical Society, 2023-07-01)
    Very-high-energy (VHE; 100 GeV < E ≤ 100 TeV) and high-energy (HE; 100 MeV < E ≤ 100 GeV) gamma rays were observed from the symbiotic recurrent nova RS Ophiuchi (RS Oph) during its outburst in 2021 August by various ...
  • Lepton loss and entropy generation in stellar collapse 
    Datta, B; Deo, P. P (D. Reidel Publishing Co., 1983-02)
    The effects of uncertainties in determining the loss of neutrinos and the generation of entropy during the collapse of a stellar core are studied using a simple spherically-symmetric homologous collapse model with an ...
  • Leptonic and hadronic modeling of Fermi-LAT hard spectrum quasars and predictions for high-energy polarization 
    Paliya, Vaidehi S; Zhang, H; Bottcher, M; Ajello, M; Domi­nguez, A; Joshi, M; Hartmann, D; Stalin, C. S (IOP Publishing, 2018-08)
    We present the results of a study of the time-averaged spectral energy distributions (SEDs) of eight flat spectrum radio quasars (FSRQs) present in the second catalog of high energy sources detected beyond 50 GeV by the ...
  • Lepto−Hadronic Origin of γ-ray Outbursts of 3C 279 
    Paliya, Vaidehi S; Diltz, C; Bottcher, M; Stalin, C. S; Buckley, D (Astronomical Society of India, 2015-03)
    The blazar 3C 279 exhibited a giant γ-ray outburst in 2013 December and 2014 April. Apart from the very fast γ-ray flux variability, the spectral nature of the flares were also found to vary significantly between these ...
  • Less is more? are radiogalaxies below the fanaroff-riley break more polarised on pc-scales? 
    Kharb, P; Shastri, P; Gabuzda, D. C (Springer, 2008)
  • Li Abundance Survey in Galactic Thin Disk 
    Lambert, D. L; Reddy, B. E (Astronomical Society of the Pacific, 2005-09)
    Lithium abundances for a sample of 451 F and G dwarfs including 181 new stars all belonging to the Galactic thin disk are discussed. Lithium abundances, metallicities ([Fe/H]), masses, and ages are determined (Lambert & ...

    Bandyopadhyay, A; Sivarani, T; Beers, Timothy C; Susmitha, A; Nayak, Prasanta K; Pandey, Jeewan C (American Astronomical Society, 2022-10-01)
    We present a study on the detailed elemental abundances of newly identified, bright, very metal-poor stars with the detection of lithium, initially observed as part of the SDSS/MARVELS pre-survey. These stars were selected ...
  • A Li-rich post-AGB star HD 172481 
    Giridhar, S; Arellano Ferro, A; Mathias, P (Astronomical Society of India, 2001)
    Our abundance analysis of this post-AGB candidate star confirms that the HD 172481 is indeed a post-AGB star. It belongs to an important, but relatively rare class of post-AGB stars showing Li I features in their spectra. ...
