  • 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. (2008)
    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. (2009)
    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 ...
  • UBV CCD standards near 5C1 radio sources at intermediate galactic latitude – I 
    Mohan, V.; Ojha, D. K.; Bienayme, O.; Paliwal, D. C.; Pandey, A. K.; Robin, A. C.; Chareton, M.; Bhatt, B. C.; Sanwal, B. B.; Oblak, E.; Haywood, M.; Creze, M. (1994)
    Using CCD observations photometric magnitudes have been obtained in 18 sub-fields in a direction at intermediate galactic latitude (l = 170°, b = 45°) in a 14 deg² area. B and V magnitudes have been obtained for a total ...
  • Young brown dwarfs in the core of the W3 main star-forming region 
    Ojha, D. K.; Tamura, M.; Nakajim, Y.; Saito, H.; Pandey, A. K.; Ghosh, S. K.; Aoki, K. (2009-03-01)
    We present the results of deep and high-resolution (FWHM ∼ 0. 35) JHK near-infrared (NIR) observations with the Subaru telescope, to search for very low mass young stellar objects in the W3 Main star-forming region. The ...
  • 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 ...
