  • Large dust grains in the dark cloud B5 
    Bhatt, H. C (Royal Astronomical Society, 1986-09)
    Polarization measurements of stars in the region of the dark cloud B5 indicate that the average dust grain size in the cloud is much larger than the mean interstellar grain size. Within the cloud, the average grain size ...
  • Large Magellanic Cloud Bar: Evidence of a Warped Bar

  • A large sample of newly identified carbon-deficient red giants from APOGEE 
    Maben, Sunayana; Bharat Kumar, Y; Reddy, B. E; Campbell, Simon W; Zhao, Gang (Oxford University Press on behalf of Royal Astronomical Society, 2023-11)
    Based on the Apache Point Observatory Galactic Evolution Experiment survey we conducted a search for carbon-deficient red giants (CDGs). We found 103 new CDGs, increasing the number in the literature by more than a factor ...
  • Large scale extinction maps with UVIT 
    Ravichandran, S; Preethi, K; Safonova, M; Murthy, J (Springer, 2013-04)
    The Ultraviolet Imaging Telescope (UVIT) is scheduled to be launched as a part of the ASTROSAT satellite. As part of the mission planning for the instrument we have studied the efficacy of UVIT observations for interstellar ...

    An ultra-sensitive, multidetector wide angle atmospheric Cerenkov telescope array is being set up at Mt. Abu for cosnic gamma-ray studies in tens of TeV energy region. The design features of the Cerenkov light detector, ...
  • Large-scale flow patterns in the solar atmosphere 
    Sivaraman, K. R (International Astronomical Union, 1990)
    One of the results of a study on the migration of H-alpha filaments, namely, the existence of meridional flow on the sun, is presented and extended to show the participation of this meridional flow in the solar cycle ...
  • The large-scale magnetic field in the global solar cycle: observational aspects 
    Makarov, V. I; Sivaraman, K. R (Springer, 1991)
    The global solar cycle is considered as an interaction of 3 types of activity: at low-latitude (sunspots), at high-latitude (polar faculae) and the weak magnetic field. The properties of single and 3-fold reversals of the ...
  • Large-scale Wind Structures in OB Supergiants: a Search for Rotationally Modulated Hα variability 
    Morel, T; Marchenko, S. V; Pati, A. K; Kuppuswamy, K; Carini, M. T (Astronomical Society of India, 2003)
    We present preliminary results of a long-term spectroscopic monitoring of a sample of bright OB-supergiants aimed at establishing the incidence of co-rotating, large-scale wind structures by detecting rotationally modulated ...
  • Large-scale wind structures in OB supergiants: a search for rotationally modulated Hα variability 
    Morel, T; Marchenko, S. V; Pati, A. K; Kuppuswamy, K; Carini, M. T; Wood, E; Zimmerman, R (The Royal Astronomical Society, 2004-06)
    We present the results of a long-term monitoring campaign of the Hα line in a sample of bright OB supergiants (O7.5-B9) which aims at detecting rotationally modulated changes potentially related to the existence of large-scale ...
