  • 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 ...
  • Embedded star clusters in the W51 giant molecular cloud 
    Nanda Kumar, M. S; Kamath, U. S; Davis, C. J (Royal Astronomical Society, 2004-10)
    We present sub-arcsecond (0.35-0.9 arcsec), near-infrared J-, H- and K-band photometric observations of six fields along the W51 giant molecular cloud (W51 GMC). Our observations reveal four new, embedded clusters and ...
  • High-latitude molecular clouds and near-by OB associations 
    Bhatt, H. C (2000-09)
    The Galactic disribution of the high-latitude molecular clouds is considered. It is suggested that the majority of these clouds are clustered in two large shells around the two closest OB associations, Per OB3/Cas-Tau and ...
  • A method to determine distances to molecular clouds using near-IR photometry 
    Maheswar, G; Lee, C. W; Bhatt, H. C; Mallik, S. G. V; Dib, S (EDP Sciences, 2010-01)
    We aim to develop a method to determine distances to molecular clouds using JHK near-infrared photometry. Methods: The method is based on a technique that aids spectral classification of stars lying towards the fields ...
  • 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 ...
