    Samal, M. R.; Pandey, A. K.; Ojha, D. K.; Ghosh, S. K.; Kulkarni, V. K.; Bhatt, B. C. (2007-12-10)
    We present the observational results of Galactic H II region Sh 2-294, using optical photometry, narrowband imaging, and radio continuum mapping at 1280 MHz, together with archival data from the 2MASS, MSX, and IRAS surveys. ...
  • A multiwavelength study of star formation in the vicinity of galactic H II region Sh2-100 
    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. (2010)
    We present multiwavelength investigation ofmorphology, 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 ...
  • Optical and near-infrared survey of the stellar contents associated with the star-forming complex Sh2-252 
    Jose, J. et. al.; Pandey, A. K.; Samal, M. R.; Chauhan, N.; Eswaraiah, C,; Yadav, R. K. (2012)
    We present the analyses of the stellar contents associated with the extended HII region Sh2- 252 using deep optical UBVRI photometry, slit and slitless spectroscopy along with the near-infrared (NIR) data from Two-Micron ...
  • Pre-main-sequence population in NGC 1893 region 
    Pandey, A. K.; Samal, M. R.; Chauhan, N.; Eswariah, C.; Pandey, J. C.; Chen, W. P.; Ojha, D. K. (2013)
    In this paper we continued our efforts to understand the star formation scenario in and around the young cluster NGC 1893. We used a sample of the young stellar sources (YSOs) identified on the basis of multiwavelength data ...
  • Pre-main-sequence population in NGC 1893 region: X-ray properties 
    Pandey, A. K.; Samal, M. R.; Yadav, Ramkesh; Richichi, Andrea; Lata, Sneh; Pandey, J. C.; Ojha, D. K.; Chen, W. P. (Elsevier, 2013-11-08)
    Continuing the attempt to understand the properties of the stellar content in the young cluster NGC 1893 we have carried out a comprehensive multi-wavelength study of the region. The present study focuses on the X-ray ...
  • Star formation activity in the galactic hii 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. (2012)
    We present a multiwavelength study of the Galactic Hii 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. The ...
  • Star formation and young population of the HII complex Sh2-294 
    Samal, M. R.; Pandey, A. K.; Ojha, D. K.; Chauhan, N.; Jose, J.; Pandey, B. (2012)
    The Sh2-294 Hii region ionized by a single B0V star features several infrared excess sources, a photodissociation region, and also a group of reddened stars at its border. The star formation scenario in this region seems ...
  • Star formation in bright-rimmed clouds and clusters associated with the W5 E H II region 
    Chauhan, N.; Pandey, A. K.; Ogura, K.; Jose, J.; Ojha, D. K.; Samal, M. R.; Mito, H. (2011)
    The aim of this paper is to present the results of photometric investigations of the central cluster of the W5 E HII region as well as a follow-up study of the triggered star formation in and around bright-rimmed clouds ...
  • 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, 2011-08-25)
    The HII 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 elephant ...
  • Young stellar population and ongoing star formation in the H II complex Sh2-252 
    Jose, J.; Pandey, A. K.; Samal, M. R.; Ojha, D. K.; Ogura, K.; Kim, J. S.; Kobayashi, N.; Goyal, A.; Chauhan, N.; Easwaraia, C. (Wiley Online, 2013-07-11)
    In this paper, an extensive survey of the star-forming complex Sh2-252 has been undertaken with an aim to explore its hidden young stellar population as well as to understand the structure and star formation history for ...
