Field of RESEARCH:
Physical processes on solid surfaces of airless bodies and their remote sensing characteristics -
application of ideas, methods and achievements of solid state physics to astronomical objects.
-
Regolith processes, effects of cosmic environment:
-
effects of solar wind and other ionizing radiation:
-
computer simulation of radiation effects in planetary regoliths,
-
sputtering of regolith, changes in stoichiometry of the implanted zones, local and global distribution of sputtered atoms and backscattered ions,
-
trapping of solar wind elements in the implanted zones, local and global distribution of trapped atoms, in particular, H and He,
-
direct chemical effects of solar wind protons:
-
-
hydrogenation and carbonization of carbon-bearing materials,
-
hydroxyl formation in the implanted zones of silicate particles;
-
effects of meteoritic bombardment:
-
the role of impact melting and evaporation in formation of nano- and micro-grains of metallic iron (nFe0 and μFe0) in lunar soils,
-
ejection from craters; local and global transport of the ejecta;
-
-
effects of high vacuum on cohesion between regolith particles and mechanical properties of planetary soils;
-
effects of surface temperature on regolith processes:
-
on global distribution of the implanted elements,
-
on survival of ices on the lunar regolith (if any),
-
on dielectric properties and radar response on silicate surfaces
-
-
Theoretical modeling of spectra of multicomponent solid surfaces with multiscale structure typical of atmosphereless bodies and spectral effects of space weathering:
-
optical spectra of mineral mixtures,
-
the effect of thin absorbing coating around particles on spectra of soils,
-
the effect of iron grains from nanometer (nFe0) to micron sizes (μFe0) on spectra of lunar and mercurian soils,
-
possible effects of the hydroxyl of solar wind origin on infrared spectra of lunar soils
Main results:
-
Theoretical model that describes spectral effects of space weathering (formation of Fe0, OH, etc.) is proposed. The model operates with physical properties of surface material (optical constants, particle sizes, concentrations of components).
-
The amount of hydrogen detected so far near the lunar poles cannot exclude the interpretation of this hydrogen as protons of solar wind chemically bound into OH-groups or trapped on radiation defects.
-
The shape and depth of 3μm absorption found in reflectance spectra all over the Moon are still consistent with hypothesis of solar wind protons bound to local oxygen and do not require presence of water molecules.
-
Presence of OH groups of solar wind origin may explain 3-μm absorption in IR spectra of E and M asteroids whose surface material is thought to be differentiated and, consequently, dehydrated.
-
High the radar brightness and depolarization of the reflected signal in polar craters of Mercury do not prove water ice, because low dielectric loss of surface material that is responsible for such radar properties can be due to low temperatures of silicate surfaces.
-
Particle cohesion and strength of regolith cannot be supposed to equal zero, which plays the key role in any process where particle elevation is involved (crater formation, electrostatic levitation, etc.)
