  • Are Nuclear Hot Spots in Galaxies Sites of Sequential Star Formation? 
    Korchagin, V; Kembhavi, A. K; Mayya, Y. D; Prabhu, T. P (The American Astronomical Society, 1995-06)
    We investigate self-regulated propagation of stars formation, which is one of the possible scenarios of stars formation in molecular clouds fragmented into cold dense structures with masses lying near the Jeans limit. ...
  • The CA II triplet lines as diagnostics of luminosity, metallicity and chromospheric activity in cool stars 
    Mallik, S. G. V (European Southern Observatory, 1997-08)
    CCD spectra of the infrared triplet lines of ionized calcium at 8498, 8542, 8662 have been obtained at a spectral resolution of 0.4 Å in 146 stars brighter than V = +7.0 spanning a range in spectral types from F7 to M4 of ...
  • Depth estimation of the large and small magellanic clouds 
    Subramanian, S; Subramaniam, A (EDP Sciences, 2009-03)
    Context: A systematic estimation of the line of sight depth in the disk and bar regions of the Large and Small Magellanic Clouds (LMC and SMC) using red clump stars is presented. Aims: We used the red clump stars from the ...
  • Evidence of a Counterrotating Core in the Large Magellanic Cloud 
    Subramaniam, A; Prabhu, T. P (The American Astronomical Society, 2005-05)
    Stellar radial velocity data in the central region of the Large Magellanic Cloud (LMC) are used to estimate its radial velocity curve along various position angles (P.A.'s), including the line of nodes (LON). The central ...
  • Line of sight depth of the large and small magellanic clouds 
    Subramaniam, A; Subramanian, S (Cambridge University Press, 2009-03)
    We used the red clump stars from the Optical Gravitational Lensing Experiment (OGLE II) survey and the Magellanic Cloud Photometric Survey (MCPS), to estimate the line-of-sight depth. The observed dispersion in the magnitude ...
  • The local stellar population of nova regions in the Large Magellanic Cloud 
    Subramaniam, A; Anupama, G. C (EDP Sciences, 2002-08)
    This study aims at identifying and understanding the parent population of novae in the Large Magellanic Cloud (LMC) by studying the local, projected, stellar population. The star formation history of the local environment ...
  • The mysterious bar of the large magellanic cloud: what is it? 
    Subramaniam, A; Subramanian, S (Institute of Physics, 2009-09)
    The bar of the Large Magellanic Cloud (LMC) is one of the prominent, but controversial, features regarding its location with respect to the disk of the LMC. In order to study the relative location of the bar with respect ...
