  • Age Sequence in Small Clusters Associated with Bright-Rimmed Clouds 
    Ogura, K; Chauhan, N; Pandey, A. K; Bhatt, B. C; Ojha, D; Itoh, Y (Astronomical Society of Japan, 2007-02)
    Bright-rimmed clouds (BRCs) found in HII regions are probable sites of triggered star formation due to compression by ionization/shock fronts, and it is hypothesized that star formation proceeds from the exciting star(s) ...
  • Champagne flow and triggered star formation in NGC 1893 
    Maheswar, G; Sharma, S; Biman, J. M; Pandey, A. K; Bhatt, H. C (Blackwell Synergy, 2007-08)
    Using Hα grism spectroscopy and optical and Two-Micron All-Sky Survey photometry of the fields containing NGC 1893 and two emission nebulae, Sim 129 and Sim 130, we show the presence of a number of Hα and near-infrared ...
  • A multiwavelength census of stellar contents in the young cluster NGC 1624 
    Jose, J; Pandey, A. K; Ogura, K; Ojha, D. K; Bhatt, B. C; Samal, M. R; Chauhan, N; Sahu, D. K; Rawat, P. S (Wiley-Blackwell, 2011-03)
    We present a comprehensive multiwavelength analysis of the young cluster NGC 1624 associated with the H ii region Sh2-212 using optical UBVRI photometry, optical spectroscopy and GMRT radio continuum mapping along with the ...
  • A multiwavelength study of star formation in the vicinity of galactic H II region Sh 2-100 
    Samal, M. R; Pandey, A. K; Ojha, D. K; Ghosh, S. K; Kulkarni, V. K; Kusakabe, N; Tamura, M; Bhatt, B. C; Thompson, M. A; Sagar, R (The American Astronomical Society, 2010-05)
    We present multiwavelength investigation of morphology, physical-environment, stellar contents, and star formation activity in the vicinity of star-forming region Sh 2-100. It is found that the Sh 2-100 region contains ...
  • Multiwavelength Study of the NGC 281 Region 
    Sharma, S; Pandey, A. K; Pandey, J. C; Chauhan, N; Ogura, K; Ojha, D. K; Borrissova, J; Mito, H; Verdugo, T; Bhatt, B. C (Astronomical Society of Japan, 2012-10)
    We present a multiwavelength study of the NGC 281 complex which contains the young cluster IC 1590 at the center, using deep wide-field optical UBV Ic photometry, slitless spectroscopy along with archival data sets in ...
  • Near-infrared JH photometry of young open cluster Be 59 
    Sharma, S; Ogura, K; Pandey, A. K; Ojha, D. K; Bhatt, B. C (Astronomical Society of India, 2007)
    We present near-infrared J H photometry and optical slitless spectroscopy of stars in the field of the young cluster Be 59. The J /(J- H )colour-magnitude diagram of the cluster yields a distance modulus of (m - M )0= 10.0 ...
  • Star Formation Activity in the Galactic H II Complex S255-S257 
    Ojha, D. K; Samal, M. R; Pandey, A. K; Bhatt, B. C; Ghosh, S. K; Sharma, S; Tamura, M; Mohan, V; Zinchenko, I (IOP Publishing, 2011-09-10)
    We present results on the star formation activity of an optically obscured region containing an embedded cluster (S255-IR) and molecular gas between two evolved H II regions, S255 and S257. We have studied the complex using ...
  • 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. ...
  • Stars at the Tip of Peculiar Elephant Trunk-Like Clouds in IC 1848E: A Possible Third Mechanism of Triggered Star Formation 
    Chauhan, N; Ogura, K; Pandey, A. K; Samal, M. R; Bhatt, B. C (Astronomical Society of Japan, 2011-08)
    The H II region IC 1848 harbors a lot of intricate elephant trunk-like structures that look morphologically different from usual bright-rimmed clouds (BRCs). Of particular interest is a concentration of thin and long ...
  • Stellar contents and star formation in the young open cluster Stock 8 
    Jose, J; Pandey, A. K; Ojha, D. K; Ogura, K; Chen, W. P; Bhatt, B. C; Ghosh, S. K; Mito, H; Maheswar, G; Sharma, S (Blackwell Publishing, 2008-03)
    We present UBVIc CCD photometry of the young open cluster Stock 8 with the aim of studying its basic properties such as the amount of interstellar extinction, distance, age, stellar contents and initial mass function (IMF). ...
  • Stellar contents and star formation in the young star cluster Be 59 
    Pandey, A. K; Sharma, S; Ogura, K; Ojha, D. K; Chen, W. P; Bhatt, B. C; Ghosh, S. K (Blackwell Publishing, 2008-01)
    We present UBV Ic CCD photometry of the young open cluster Be 59 with the aim to study the star formation scenario in the cluster. The radial extent of the cluster is found to be ~10 arcmin (2.9 pc). The interstellar ...
  • Triggered star formation and evolution of T-Tauri stars in and around bright-rimmed clouds 
    Chauhan, N; Pandey, A. K; Ogura, K; Ojha, D. K; Bhatt, B. C; Ghosh, S. K; Rawat, P. S (Blackwell Publishing, 2009-06)
    The aim of this paper is to quantitatively testify the `small-scale sequential star formation' hypothesis in and around bright-rimmed clouds (BRCs). As a continuation of the recent attempt by Ogura et al., we have carried ...
