Ionization Structure

Symbiotic stars are long-period interacting binaries consisting of a cool giant as the donor star and a white dwarf as the acretor. Due to acretion of the material from the giant’s stellar wind, the white dwarf becomes very hot and luminous. The circumstellar material partially ionized by the hot star, represents an ideal medium for processes of scattering. To investigate the symbiotic nebula we modeled the wide wings of the resonance lines OVI λ1032 Å, λ1038 Å and HeII λ1640 Å emission line in the spectrum of AG Dra, broadened by Thomson scattering. On the other hand, Raman and Rayleigh scattering arise in the neutral part of the circumstellar matter around the giant and provide a powerful tool to probe e.g. the ionization structure of the symbiotic systems and distribution of the neutral hydrogen atoms in the giant’s wind.

Two Phases

In-situ alloying of polypropylene (PP)/polystyrene (PS) binary polymer blends using anhydrous aluminum chloride as a catalyst was investigated by small angle light scattering. The phase structures, morphology, and compatibilization effect in the obtained alloys during the in-situ alloying process were investigated by Rayleigh scattering. The content of compatible domains between the two phases of PP and PS in the in-situ alloys, i.e. the volume fraction of the interfacial transition layer, and the ‘invariant’ of the alloys were first calculated to describe the in-situ alloying dynamics, which reveals that the resulting in-situ PP/PS alloys are partially compatible. The relationship between the volume fraction of the interfacial transition layer or ‘invariant’ and the in-situ alloying reactive conditions are discussed in detail. The phase structural parameters, including correlation distance and average chord lengths, were calculated to characterize the phase size evolutions of the in-situ alloys, confirming the validity of using the volume fraction of the interfacial transition layer or ‘invariant’ to investigate the in-situ alloying dynamics.
