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.

    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.
