  • Near IR lunar occultation observations and results from Gurushikhar observatory 
    Chandrasekhar, T (Astronomical Society of India, 1999)
    Lunar occultation in the near infrared is an elegant and effective technique of achieving high angular resolution in the range of milliarcseconds. Apart from determining with good accuracy the angular diameter and effective ...
  • 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 ...
  • Near-Infrared Investigations of Star Forming Regions 
    Anandarao, B. G (Astronomical Society of India, 2002-09)
    We have initiated an observational programme on star formation using the 256 x 256 HgCd'Th Infrared Array Camera.(NICMOS3) at the 1.2 m m telescope in Mt. Abu. The observations, being made in the spectral region 1-2.5 pm, ...
  • Near-infrared JH photometry of young open cluster Be 59
