  • Near infrared photometry of the young clusters NGC 1960, NGC 2453 and NGC 2384 
    Hasan, P (Astronomical Society of India, 2005-09)
    Infrared observations of young star clusters provide vital clues to the star formation process and evolution of stars. This brief report on my thesis gives a brief description of the observations and analysis of the young ...
  • Near infrared photometry of the young clusters NGC 1960, NGC 2453 and NGC 2384 
    Hasan, P (Astronomical Society of India, 2005-06)
    The present paper gives a brief description of the observations and analysis of the young star clusters NGC 1960, NGC 2453 and NGC 2384 observed in the near infrared bands at the Mt Abu Infrared Observatory, Gurushikhar ...
  • Near infrared photometry of the young open cluster NGC 1960 
    Hasan, P; Kilambi, G. C; Baliyan, K. S (Astronomical Society of India, 2002-09)
    We present the preliminary results of observations of NGC 1960 which was observed from the Mt Abu Infrared Observatory, using the NICMOS3 infrared array mounted on the 1.2 m Cassegrain focus telescope. The observations ...
  • Near Infrared Photometry of the Young Star Cluster NGC 2384 
    Hasan, P; Kilambi, G. C; Baliyan, K. S (Astronomical Society of India, 2003)
    This work involves near infrared photometry of the young cluster NGC 2384. Observations were taken at the Mt Abu Infrared Observatory using the NIC-MOS3 detector in February 2000. The distance to the cluster is obtained ...
  • Near IR study of the young cluster NGC 2453 
    Hasan, P; Kilambi, G. C; Baliyan, K. S (Astronomical Society of India, 2001)
    In an attempt to understand early phases of stellar evolution and star formation, we have taken up the study of extremely young star clusters in the near infrared wavebands. These clusters are deeply embedded inside the ...
  • Search for low-mass objects in the globular cluster M4. I. detection of variable stars 
    Safonova, M; Mkrtichian, D; Hasan, P; Sutaria, F. K; Brosch, N; Gorbikov, E; Joseph, P (IOP Publishing, 2016-02)
    With every new discovery of an extrasolar planet, the absence of planets in globular clusters ( GCs ) becomes more and more conspicuous. Null detection of transiting hot Jupiters in GCs 47 Tuc, ω Cen, and NGC 6397 ...
