  • Parthasarathy, M (The European Southern Observatory, 1991-07)
    The existence of a dust shell and warm dust near HD 100764 are determined from IRAS observations of early R stars, and the ramifications of the findings are discussed. The mass of the dust shell is calculated to be 0.510 ...

    HISPEC is a new, high-resolution near-infrared spectrograph being designed for the W.M. Keck II telescope. By offering single-shot, R 100,000 spectroscopy between 0.98 – 2.5 µm, HISPEC will enable spectroscopy of transiting ...
  • Kameswara Rao, N; Nandy, K (Bruxelles : Palais des Académies, 1988)
    Radio and Brackett gamma observations indicate large value of reddening E(B - V) = 1.5 to the nebula surrounding V348 Sgr, where as the star appears to be reddened by only E(B - V) is approximately 0.4. The infrared ...

    Indian Astronomical 0 bserva,tory, Hanle, is the high altitude (4500 in above msl) observat.ory operated by the Indian Institute of Astrophysics, Bangalore. The 2-m Himalayan Chandra Telescope (HCT) inst.alled in the ...
  • 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 ...
