  • The outburst and nature of young eruptive low mass stars in dark clouds 
    Ninan, J. P; Ojha, D. K; Bhatt, B. C; Mallick, K. K; Tej, A; Sahu, D. K; Ghosh, S. K; Mohan, V (Astronomical Society of India, 2012)
    The FU Orionis (FUor) or EX Orionis (EXor) phenomenon has attracted increasing attention in recent years and is now accepted as a crucial element in the early evolution of low-mass stars. FUor and EXor eruptions of young ...
  • Reappearance of McNeil’s Nebula (V1647 Orionis) and its Outburst Environment 
    Ninan, J. P; Ojha, D. K; Bhatt, B. C; Ghosh, S. K; Mohan, V; Mallick, K. K; Tamura, M; Henning, T (IOP Publishing, 2013-12-01)
    We present a detailed study of McNeil's nebula (V1647 Ori) in its ongoing outburst phase starting from 2008 September to 2013 March. Our 124 nights of photometric observations were carried out in optical V, R, I, and ...
  • Sh2-138: physical environment around a small cluster of massive stars 
    Baug, T; Ojha, D. K; Dewangan, L. K; Ninan, J. P; Bhatt, B. C; Ghosh, S. K; Mallick, K. K (Oxford University Press on behalf of the Royal Astronomical Society, 2015-12-21)
    We present a multiwavelength study of the Sh2-138, a Galactic compact H II region. The data comprise of optical and near-infrared (NIR) photometric and spectroscopic observations from the 2-m Himalayan Chandra Telescope, ...
  • Star Formation Activity in the Galactic H II Region Sh2-297 
    Mallick, K. K; Ojha, D. K; Samal, M. R; Pandey, A. K; Bhatt, B. C; Ghosh, S. K; Dewangan, L. K; Tamura, M (IOP Publishing, 2012-11-01)
    We present a multiwavelength study of the Galactic H II region Sh2-297, located in the Canis Major OB1 complex. Optical spectroscopic observations are used to constrain the spectral type of ionizing star HD 53623 as B0V. ...
