Yurij G. Shkuratov
Date and place of birth: 23 September 1952, Ivano-Frankovsk, Ukraine
Education: 1970-1975, Physics Department of the Kharkov State University.
Position: Head of Department "Remote Sensing of Planets" (Kharkov Astronomical
Observatory).
Titles: PhD (1980), Doctor of Sciences (1993), and Professor (1999)
Prizes:
The State Prize of Ukraine in the Field of Sciences
(1986).
The Prize of the National Academy of Sciences of Ukraine
(1997).
I am an author and co-author of more than 300 scientific works devoted
to studies of optical properties of the lunar surface as well as the surfaces
of other atmosphereless celestial bodies.
Main Results and Fields of interests:
I have obtained first images of the Moon for a new polarimetric parameter
which turned out to be the source of information about the average size
of lunar regolith particles.
I performed the numerous laboratory photometric and polarimetric measurements
of structure analogs of the lunar regolith (more than 1000 different samples)
which provided a reliable experimental basis for the verification and selection
of the theoretical models for the opposition effect and negative polarization.
I contributed to theoretical models of the light scattering by the surfaces
with complicated structure. In particular, I proposed the model of the
negative polarization of light based on the mechanism of the coherent backscatter
enhancement.
At present my scientific activity is in particular focused on studies
of optical properties of the lunar surface on the base of Clementine data.

Nickolaj V. Opanasenko
Ph.D. thesis: “Simultaneous photometry and polarimetry of lunar sites”.
Scientific interests:
simultaneous telescope observations of photometric, polarimetric and
colorimetric characteristics of lunar sites;
obtaining images of albedo, color-index, phase brightness gradients
and polarimetric characteristics by digital processing of photographic
images;
investigation of relations between photometric, polarimetric,
indicatometric and colorimetric characteristics of atmosphereless celestial
bodies;
remote sensing of content and structure of the lunar surface by
its photometric, polarimetric, colorimetric and indicatometric characteristics;
using the ground telescope data for calibration and absolutisation
data obtained by spacecrafts.

Larissa V. Starukhina
Being a solid state physisist among astronomers, she
applies ideas, methods and achievements of her science to astronomical
objects. She consideres the surfaces of as physical laboratories with vacuum
so pure that any terristrial laboratory may only dream about it.
She studies the effect of cosmic environment on the
spectra of particulate solid surfaces. To work with complicated multiscale
structure and composition characterictic of the surfaces of atmosphereless
celestial bodies, she developped the theoretical model of spectral albedo
proposed by Yurij Shkuratov (1987) to
different types of inhomogeneity of the surface and particles. She
applied the model to the various objects, e.g., lunar regolith, Phobos,
meteorites.
Her recent studies are devoted to the ice on the Moon.
As the first announcement about the Lunar Prospector finding appeared,
she asked: "Is it really ice that was found?" As she calculated, the amount
of ice reported can be explained by chemical trapping of hydrogen in regolith
particles: near the cold lunar poles the trapping can proceed to
saturation. |
