  • Behaviour of some neutral molecular absorption lines in facula models 
    Tripathi, B. M; Sinha, K; Pande, M. C (Astronomical Society of India, 1982-12)
    The equivalent widths of some selected absorption lines of C2, Ch, MgH, NH, OH and SH molecules in five facula and two photospheric models have been calculated under the assumption of LTE. The calculations reveal that the ...
  • Brackett-gamma line and facula models 
    Tripathi, B. M; Pande, M. C (Astronomical Society of India, 1981-12)
    An attempt has been made to show that the profile of the Brackett-gamma line can distinguish between different facula models. It is suggested that low noise high resolution scans of Brackett lines can help improve the ...
  • Carbon monoxide and facula models 
    Tripathi, B. M; Pande, M. C; Sinha, K (Astronomical Society of India, 1982-06)
    Equivalent widths for a new lines of the first overtone band of carbon monoxide have been calculated in the solar infrared spectrum for five facular and two photospheric models. The calculations show a decrease in equilavent ...
  • CH and CH/sup+/ Lines in Facula Models 
    Tripathi, B. M (Astronomical Society of India, 1978-09)
    Equivalent width calcultions for CH and CH/sup+/ are carried out in three facula models. For CH, the lamda4313.662 A line of the (0-0) band of the transition /sup2/ Delta - /sup2/II of the Q1c branch, and for CH/sup+/, the ...
  • Evolution of Sunspots Seen in Molecular Lines - Part Two 
    Sinha, K; Tripathi, B. M (Astronomical Society of India, 1991)
  • Evolution of sunspots seen in molecular lines. I 
    Sinha, K; Tripathi, B. M (Astronomical Society of India, 1991)
    Equivalent-width calculations are conducted for lines of C2, MgH, and TiO relevant to photospheric and sunspot model atmospheres to determine the effects of magnetic field strength on line intensities. Sunspot models with ...
  • Ionized molecules in facula models 
    Tripathi, B. M; Gaur, V. P; Pande, M. C (Astronomical Society of India, 1981-09)
    Equivalent widths for the lines of ionized molecules AlH+, CH+, CN+ CO+, N2+, NH+, OH+ and SiH+ have been calculated in five facular and two photospheric models. The calculations suggest that CH+ should show up in facular ...
  • On ionized molecules in the solar atmosphere 
    Sinha, K; Tripathi, B. M (Astronomical Society of India, 1990-03)
    The partial pressures of 20 ionic molecular species are reported for standard facular, photospheric, and sunspot model atmospheres with a view to picking up ionized molecules for a possible identification in the solar ...
  • On the oscillator strength and the dissociation energy of CN molecules 
    Sinha, K; Tripathi, B. M (Astronomical Society of Indian, 1986-03)
    Equivalent widths of the CN red system in the solar spectrum are determined and compared with previous observational data in order to evaluate various published values for oscillator strength and dissociation energy. The ...
  • Solar Photospheric Models and the Rotational Temperatures of THE C/sub2/ and MgH Molecules 
    Sinha, K; Shukla, D. S; Tripathi, B. M (Astronomical Society of India, 1979-06)
    Four photospheric models have been utilized to derive model based rotational temperatures of the (0-0) band of the Swan system of C/sub2/ and that of the green system of the MgH molecules. The dissociation energies were ...
