  • Post-outburst phase of McNeil's nebula (V1647 Orionis) 
    Ojha, D. K; Ghosh, S. K; Tej, A; Verma, R. P; Vig, S; Anupama, G. C; Sahu, D. K; Parihar, P. S; Bhatt, B. C; Prabhu, T. P; Maheswar, G; Bhatt, H. C; Anandarao, B. G; Venkataraman, V (Blackwell Publishing, 2006-03)
    We present a detailed study of the post-outburst phase of McNeil's nebula (V1647 Orionis) using optical B, V, R, I and near-infrared (NIR) J, H, K photometric and low-resolution optical spectroscopic observations. The ...
  • Simultaneous infrared and H-alpha measurements of Be stars 
    Apparao, K. M. V; Tarafdar, S. P; Verma, R. P; Iyengar, K. V. K; Ghosh, K. K (Indian Academy of Sciences, 1993)
    The observed infrared excess in Be stars is usually interpreted as free-free and free-bound emission from a hot gas envelope around the Be star. This hot gas should also emit H-alpha line radiation. Earlier observations ...
  • A Study of the Galactic Star Forming Region IRAS 02593+6016 / S 201 in Infrared and Radio Wavelengths 
    Ojha, D. K; Ghosh, S. K; Kulkarni, V. K; Testi, L; Verma, R. P; Vig, S (Astronomical Society of India, 2003)
    We present infrared and radio observations of IRAS 02593+6016 / S 201 star forming region. A young star cluster is observed in this region, which contains different classes of young stellar objects. The near-infrared (NIR) ...
  • A two band far-infrared photometer with bolometer arrays 
    Verma, R. P; Rengarajan, T. N; Ghosh, S. K (Astronomical Society of India, 1993)
    A new two band photometer for the Tata Institute of Fundamental Research (TIFR) 1m balloon-borne telescope is described. The detector system consists of two arrays (of six detectors each) of liquid He-3 cooled bolometers. ...
