Composite Circumstellar Dust Grains
Ranjan Gupta, Dipak B. Vaidya, Rajeshwari Dutta
We calculate the absorption efficiencies of composite silicate grains with inclusions of graphite and silicon carbide in the spectral range 5--25. We study the variation in…
The Dust Content and Radiation Fields of Sample of Galaxies in the ELAIS-N1 Field
P. Shalima, Rupjyoti Gogoi, Amit Pathak +3
The Mid-IR colors () of galaxies together with their IR-UV luminosity correlations can be used to get some insight into the relative abundance of the different dust g…
Interstellar Extinction by Spheroidal Dust Grains
Ranjan Gupta, Tadashi Mukai, D. B. Vaidya +2
Observations of interstellar extinction and polarization indicate that the interstellar medium consists of aligned non-spherical dust grains which show variation in the interstella…
Scattering properties and composition of cometary dust
Ranjan Gupta, D. B. Vaidya, J. S. Dobbie +1
Composition of Comet dust obtained by the dust impact analyser on the Halley probes indicated that the comet dust is a mixure of silicate and carbonaceous material. The collected i…
