  • The CMF as provenance of the stellar IMF? 
    Anathpindika, S (Elsevier B.V., 2011-12)
    In the present work we examined the hypothesis that, a core mass function (CMF), such as the one deduced for cores in the Orion molecular cloud (OMC), could possibly be the primogenitor of the stellar initial mass function ...
  • Collision between dissimilar clouds: stability of the bow-shock, and the formation of pre-stellar cores 
    Anathpindika, S (Wiley Blackwell, 2010-07)
    We use smoothed particle hydrodynamics (SPH) to simulate a head-on collision between two physically dissimilar clouds, and investigate the dynamical stability of the post-collision bow-shock. The shock-front appears ...
  • The contagion of star-formation: its origin 
    Anathpindika, S (Astronomical Society of India, 2012)
    Dense pockets of cold, molecular gas preclude the formation of stars. During their infancy and later phases of evolution, stars inject considerable energy into the interstellar medium by driving shocks either due to ionising ...
  • Does a prestellar core always become Tracing? protostellar the evolution of cores from the prestellar to protostellar phase 
    Anathpindika, S; Di Francesco, J (Oxford University Press on behalf of the Royal Astronomical Society, 2013-04-11)
    Recently, a subset of starless cores whose thermal Jeans mass is apparently overwhelmed by the mass of the core has been identified, e.g. the core L183. In the literature, massive cores such as this one are often referred ...
  • India's tryst with modern astronomy 
    Anathpindika, S (Wiley-Blackwell, 2011-08)
    Research in astronomy within India has increased substantially over the past two decades, catapulted by growing public awareness of the subject, and aided by the efforts of amateur astronomy groups in several towns and ...
  • On the evolution of irradiated turbulent clouds: a comparative study between modes of triggered star formation 
    Anathpindika, S; Bhatt, H. C (Wiley-Blackwell, 2012-12)
    Gas within molecular clouds (MCs) is turbulent and unevenly distributed. Interstellar shocks such as those driven by strong fluxes of ionizing radiation (IR) profoundly affect MCs. While small dense MCs exposed to a strong ...
  • On the interaction of a thin, supersonic shell with a molecular cloud 
    Anathpindika, S; Bhatt, H. C (Wiley-Blackwell, 2011-04)
    Molecular Clouds (MCs) are stellar nurseries; however, formation of stars within MCs depends on the ambient physical conditions. MCs, over a free-fall time, are exposed to numerous dynamical phenomena, of which, the ...
  • On the propensity of the formation of massive clumps via fragmentation of driven shells 
    Anathpindika, S (Elsevier B.V., 2011-08)
    Early type massive stars drive thin, dense shells whose edges often show evidence of star-formation. The possibility of fragmentation of these shells, leading to the formation of putative star-forming clumps is examined ...
  • On turbulent fragmentation and the origin of the stellar IMF 
    Anathpindika, S (Elsevier, 2013-01)
    Two varieties of the universal stellar initial mass function (IMF) viz., the Kroupa and the Chabrier IMF, have emerged over the last decade to explain the observed distribution of stellar masses. The possibility of the ...
  • Supersonic cloud collision. I 
    Anathpindika, S (EDP Sciences, 2009-09)
    It has long been suggested that shocks might play an important role in altering the form of the interstellar medium (ISM). Shocks enhance gas density and sufficiently dense regions may become self gravitating. Potential ...
  • Supersonic cloud collision. II 
    Anathpindika, S (EDP Sciences, 2009-09)
    Aims. In this second paper of the sequel of two papers, we continue to investigate the problem of molecular cloud (MC) collision. The companion paper to this one considered highly supersonic cloud collisions and examined ...
