  • Optical Photometric and Polari metric investigation of NGC 1931 
    Pandey, A. K; Eswaraiah, C; Sharma, S; Samal, M. R; Chauhan, N; Chen, W. P; Jose, J; Ojha, D. K; Yadav, Ram Kesh; Chandola, H. C (IOP Publishing, 2013-02-05)
    We present optical photometric and polarimetric observations of stars toward NGC 1931 with the aim of deriving cluster parameters such as distance, reddening, age, and luminosity/mass function as well as understanding dust ...
  • Photometric variable stars in the young open cluster NGC 6823 
    Lata, Sneh; Chen, W. P; Pandey, J. C; Dileep, Athul; Ai, Zhong-Han; Hojaev, Alisher S; Panwar, Neelam; Joshi, Santosh; Mondal, Soumen; Biswas, Siddhartha; Bhatt, B. C (Oxford University Press on behalf of Royal Astronomical Society, 2023-03)
    We present stellar variability towards the young open cluster NGC 6823. Time series V- and I-band CCD photometry led to identification and characterization of 88 variable stars, of which only 14 have been previously ...
  • Star formation in young cluster NGC 1893 
    Sharma, S; Pandey, A. K; Ojha, D. K; Chen, W. P; Ghosh, S. K; Bhatt, B. C; Maheswar, G; Sagar, R (International Astronomical Union, 2008-05)
    We have carried out a multi-wavelength study of the star forming region NGC 1893 to make a comprehensive exploration of the effects of massive stars on low mass star formation. Using deep optical U BV RI broad band, Hα ...
  • Star formation in young star cluster NGC1893 
    Sharma, S; Pandey, A. K; Ojha, D. K; Chen, W. P; Ghosh, S. K; Bhatt, B. C; Maheswar, G; Sagar, R (Blackwell Publishing, 2007-09)
    We present a comprehensive multiwavelength study of the star-forming region NGC 1893 to explore the effects of massive stars on low-mass star formation. Using near-infrared colours, slitless spectroscopy and narrow-band ...
  • 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 ...
  • Young stellar population of bright-rimmed clouds BRC 5, BRC 7 and BRC 39 
    Panwar, N; Chen, W. P; Pandey, A. K; Samal, M. R; Ogura, K; Ojha, D. K; Jose, J; Bhatt, B. C (Oxford University Press on behalf of the Royal Astronomical Society, 2014-09-11)
    Bright-rimmed clouds (BRCs), illuminated and shaped by nearby OB stars, are potential sites of recent/ongoing star formation. Here we present an optical and infrared photometric study of three BRCs: BRC 5, BRC 7 and BRC ...
