Dusty plasmas with high electron depletion
Dusty plasmas with high electron depletion occur in a wide range of astrophysical and laboratory environments and constitute a strongly non-equilibrium plasma regime that is still not fully understood. In particular, the interaction of nanodust with the plasma, the resulting electron depletion, and …

Circumstellar Distribution of Dust Grains Around Proto -Planetary Nebulae: Observational Evidence for Axisymmetry and 2.5-D Radiative Transfer Model Calculations
… Largely spherically symmetric circumstellar dust shells of AGB stars are known to evolve into mostly axisymmetric PNs. Since the PPN phase predates the period of final PN shaping due to interacting stellar winds, the PPN shells preserve pristine records of AGB mass loss histories. Hence, the …

Planet formation, resonant drag instabilities, and vortices
… planets form from the aggregation of countless dust grains early in the life of almost every protoplanetary disc . I then describe the main stages of the leading ‘core acccretion’ scenario: Brownian coagulation, turbulent coagulation, the metre-scale barrier, planetesimal accretion, pebble …

New-Measurement Techniques to Diagnose Charged Dust and Plasma Layers in the Near-Earth Space Environment Using Ground-Based Ionospheric Heating Facilities
… />source region associated with mesospheric dusty space plasmas may be modulated by radio wave heating with ground-based ionospheric heating facilities. These experiments show great promise as a diagnostic for the associated dusty plasma in the Near-Earth Space Environment which is believed …
