Investigating Dusty Plasma of Cometary Coma with Nasa Stardust Data
Introduction: Harbingers of doom or prophesy for the ancient peoples of Earth, comets are now understood to be primordial fragments from our Solar System's birth composed of various ices and dust species. Among the questions surrounding comets and their elusive character are the properties and processes of the rarefied gasses and disperse dust that surround their solid nucleus. Dusty, or comple...
متن کاملPlasma Flow Past Cometary and Planetary Satellite Atmospheres
The tenuous atmospheres and ionospheres of comets and outer planet satellites share many common properties and features. Such similarities include a strong interaction with their outer radiation, fields and particles environs. For comets the interaction is with the magnetized solar wind plasma, whereas for satellites the interaction is with the strongly magnetized and corotating planetary magne...
متن کاملA miniature sensor for electrical field measurements in dusty planetary atmospheres
Dusty phenomena such as regular wind-blown dust, dust storms, and dust devils are the most important, currently active, geological processes on Mars. Electric fields larger than 100 kV/m have been measured in terrestrial dusty phenomena. Theoretical calculations predict that, close to the surface, the bulk electric fields in martian dusty phenomena reach the breakdown value of the isolating pro...
متن کاملHyperspectral Estimation of Aerosol Parameters and Water-Leaving-Radiance in Dusty Atmospheres
The scientific aims that motivate our work on this project are: (1) to understand quantitatively the multiple-scattering physics underlying spaceborne hyperspectral and lidar observations of atmospheric aerosols and surface reflectivity; (2) to develop rigorous, stable (i.e., genuinely useful) inverse methods to interpret such observations in terms of geophysical quantities, based on the mathem...
متن کاملEvolutionary models for very-low-mass stars and brown dwarfs with dusty atmospheres
We present evolutionary calculations for very-low-mass stars and brown dwarfs based on synthetic spectra and non-grey atmosphere models which include dust formation and opacity, i.e. objects with Teff < ∼ 2800 K. The interior of the most massive brown dwarfs is shown to develop a conductive core after ∼ 2 Gyr which slows down their cooling. Comparison is made in optical and infrared color-magni...
