Measurement of vector magnetic fields. I - Theoretical approach to the instrumental polarisation of the Kodaikanal Solar Tower

Balasubramaniam, K. S; Venkatakrishnan, P; Bhattacharyya, J. C (D. Reidel Publishing Co., 1985-09)

The observations of Stokes line profiles require an accurate knowledge of the instrumental polarisation caused by optical components in the path of the light beam. In this context we present a theoretical approach to the ...
Optical colours and polarization of a model reflection nebula. II. Silicate and graphite grains in a nebula with the star in the rear

Shah, G. A (WILEY-VCH Verlag Berlin GmbH & Co, 1977)

The colour difference between the star and the attendant reflection nebula and polarization both caused by silicate and graphite grains have been given. The properly normalized size distribution function for each type of ...
Optical colours and polarization of a model reflection nebula. III - Composite and mixture of grains in the nebula with the star in the rear

Shah, G. A (Indian Academy of Sciences, 1977-11)

The colour differences between the star and the associated reflection nebula and polarization caused by core mantle grains and mixture of grains have been given. They are based on homogeneous plane-parallel slab-model of ...
