Laboratory light scattering from regolith surface and simulation of data by Hapke model
S. Deb, A. K. Sen
The small atmosphereless objects of our solar system, such as asteroids, the moon are covered by layer of dust particles known as regolith, formed by meteoritic impact. The light s…
The effect of gravitation on the polarization state of a light ray
T. Ghosh, A. K. Sen
In the present work the rotation of polarization vector due to the gravitational field of a rotating body has been derived, from the general expression of Maxwell's equation in the…
Deflection of light ray due to a charged body using Material Medium Approach
Saswati Roy, A. K. Sen
The gravitational deflection of light ray is an important prediction of General Theory of Relativity. In this paper we develop analytical expression of the deflection of light ray…
Distance estimation of some selected small Bok globules
A. Das, H. S. Das, A. S. Devi
The distance determination of small Bok globules is often difficult because of its small size and opaqueness. In this work, we determine the distances to six small Bok globules CB…
Imaging polarimetry of comets C/2013 V1 (Boattini) and 290P/Jager before and after perihelion
P. Deb Roy, P. Halder, H. S. Das +1
We report the results obtained from the optical polarimetric study of the light scattered by comets C/2013 V1 (Boattini) and 290P/Jager at lower phase angles. The polarimetric obse…
Light deflection in Kerr field for off-equatorial source
Sarani Chakraborty, A. K. Sen
Deflection angle for a light ray travelling in the equatorial plane of a rotating Kerr mass has been already calculated by various investigators. Considering the light ray to be tr…
