Numerical Methods for Mie Theory of Scattering by a Sphere

Shah, G. A (Indian Institute of Astrophysics, Bangalore, 1977)

A new procedure for evaluating the basic quantities connected with the Mie theory of scattering by a sphere is presented. Some independent numerical techniques are developed to enable one to achieve the desired accuracy. ...
Intensity Fluctuation in the Solar Chromosphere

Sivaraman, K. R; Venkitachalam, P. P (Indian Institute of Astrophysics, Bangalore, 1977)

High resoulution spectrograms of the Balmer lines obtained at five positions from the centres to the limb have been used to study the r. m. s. intensity fluctuations and their dependence on the heliocentric angle. The ...
The Wolf-Rayet Spectrscopic Binary HD 214419

Bappu, M. K. V; Visvanadham, P (Indian Institute of Astrophysics, Bangalore, 1977)

Velocity curves of the system HD 214419 are obtained for the N IV 4058 and He II 4686 emission lines from prismatic spectra taken in 1951 and 1952. The emission and absorption features experience several phase dependent ...
Early Nebular Stage of Nova Cygni, 1975

Prabhu, T. P (Indian Institue of Astrophysics, Bangalore, 1977)

The emission line profiles of the spectrum of the spectrum of the envelope of Nova V 1500 Cyg, 1975 are studied. The spectral region covers LamdaLamda 3700-8800. The velocity structure of the profiles and the time variation ...
A Survey of Red Stars in the Direction of the Large Magellanic Cloud: The 30 Doradus Region

Bappu, M. K. V; Parthasarathy, M; Scaria, K. K (Indian Institute of Astrophysics, Bangalore, 1977)

We have commenced a survey of red stars in the direction of the Large Magellanic Cloud using the technique of ultra-low dispersion spectroscopy. This first paper is a listing of the red stars in the 30 Doradus region for ...
The Near Infrared Spectra of Wolf Rayet Stars

Bappu, M. K. V; Ganesh, K. S; Scaria, K. K (Indian Institute of Astrophysics, Bangalore, 1977)

The near infrared spectra of three Wolf-Rayet stars of the carbon sequence and five of the nitrogen sequence have been studied. Wavelength identifications and intensity scans are presented to show the emission line ...
Ultra-low dispersion spectroscopy of stars and galaxies

Bappu, M. K. V; Parthasarathy, M (Indian Institute of Astrophysics, Bangalore, 1977)

Application of ultra-low dispersion spectroscopy (10.000 Å mm-1) is described to study the nuclei of elliptical galaxies, the quassi - stellar objects and for the discovery of faint OB stars, reddened stars and red stars. ...
An Automated Spectrum Scanner

Bappu, M. K. V (Indian Institute of Astrophysics, Bangalore, 1977)

A rapid-scan single channel spectrum in the Ebert-Fastie arrangement has been constructed and successfully used on the Kavalur 102-cm reflector. The special region 3000-11000 Armstrong is covered with appropriate dry-ice ...
Fundamental Flux Tubes in the Solar Magnetic Fileds: Significance of the Flux-amount; possibility of rising and durability

Gokhale, M. H (Indian Institute of Astrophysics, Bangalore, 1977)

For a satisfactory understanding of the solar magnetic phenomena it may be advantageous first to interrelate phenomenologically observations involving different scales of length and time and in different layers of the solar ...
