  • Identification of AlF Molecular Lines in Sunspot Umbral Spectra 
    Bagare, S. P; Balachandra Kumar, K; Rajamanickam, N (Springer, 2006-03)
    High resolution FTS sunspot umbral spectra from NSO/Kitt Peak were used to detect rotational lines due to 11 electronic transitions of the molecule AlF, in the wavelength region 4400 9000 Å. The presence of lines due to ...
  • Identification of beryllium hydride isotopomer lines in sunspot umbral spectra 
    Shanmugavel, R; Bagare, S. P; Rajamanickam, N; Balachandra Kumar, K (Astronomical Observatory, Serbia, 2008-06)
    A high resolution spectrum of FTS sunspot umbra of NSO/Kitt Peak was used to conduct a search for the molecular absorption lines due to BeH, BeD and BeT isotopomers. Analysis led to estimates of identification of the ...
  • Identification of CrH and CrD molecular lines in the sunspot umbral spectrum 
    Viswanathan, B; Shanmugavel, R; Bagare, S. P; Rajamanickam, N; Sriramachandran, P (Springer, 2009-07)
    High-resolution Fourier transform spectrometer sunspot umbral spectra obtained at the National Solar Observatory/Kitt Peak were used to identify molecular rotational lines arising from the infrared band systems of CrH and ...
  • Identification of emission bands in P/Halley 
    Bhattacharyya, J. C; Babu, G. S. D; Ghosh, K. K; Jayakumar, K; Appakutty, M (Indian Academy of Sciences, 1986)
    Spectrophotometric studies of P /Halley (r = 1.98 AU, Δ= 1.19AU, r = 1.97, Δ = 1.16 AU and r = 1.95 AU, Δ. = 1.13 AU) in the spectral range 3900 A - 6450 A were made on three nights and identifications of emission features ...
  • Identification of infrared sources in the IRAS circulars 
    Seal, P (Kluwer Academic Publishers, 1985-07)
    From IRAS (Infrared Astronomical Satellite) Circulars Nos. 4 to 15, 110 infrared sources have been identified. Out of these 110 identified sources 99 are galaxies, nine are nebulae, one is a dark object, and one is a ...
  • Identification of large-scale (>100 kpc) radio jets in narrow-line seyfert 1 galaxies 
    Umayal, S; Paliya, Vaidehi S; Saikia, D. J; Stalin, C. S; Muneer, S; Maheswar, G (American Astronomical Society, 2025-12-10)
    Powerful, large-scale relativistic jets are usually associated with massive, old elliptical galaxies. This paradigm has recently been challenged by the identification of narrow-line Seyfert 1 (NLSy1) galaxies, thought to ...
  • Identification of metal-poor stars using the artificial neural network 
    Giridhar, S; Goswami, A; Kunder, A; Muneer, S; Selvakumar, G (EDP Sciences, 2013-08)
    Context. Identification of metal-poor stars among field stars is extremely useful for studying the structure and evolution of the Galaxy and of external galaxies. Aims. We search for metal-poor stars using the artificial ...
  • Identification of new CeO features in the S star Pi Gruis 
    Murty, P. S (Gordon and Beach, Science Publishers, 1983)
    Spectrograms in the 6040-7300 A wavelength region of the S star Pi Gruis reveal the presence of new molecular features attributable to CeO. Measures of band heads compared reasonably well with the laboratory spectrum. The ...
  • Identification of SrF molecular lines in the spectrum of sunspot umbra 
    Sriramachandran, P; Shanmugavel, R; Bagare, S. P; Rajamanickam, N (Springer, 2009-09)
    A high resolution spectrum of a sunspot umbra is used for identification of rotational lines due to (0, 0) band of the A 2Π–X 2Σ+ system and (0, 0), (1, 1), and (2, 2) bands of the B 2Σ+–X 2Σ+ system of the molecule ...
  • Identification of the Source Region of a ``Halo'' Coronal Mass Ejection Using Meter-Wavelength Radio Data 
    Kathiravan, C; Ramesh, R (The American Astronomical Society, 2005-07)
    We present meter-wavelength observations of the solar corona close to the onset of the ``halo'' coronal mass ejection (CME) of 1998 January 21 and estimate the change in electron density with time through a reproduction ...
