EDUCATION AND TRAINING

Space factors of disasters on Earth. Observations, analysis, informatization

Research Fields:
Astronomy

Previous and Current Research

Main field of research

  • Physics of comet
Other fields
  • Development of astronomy device, astronomical software
Current research interest
  • Potentially dangerous space factors
  • Spectroscopy and photometry of comets
  • Morphology of comets
  • Star occultations by moon
  • Anomaly meteors

   Our group carries out regular spectral and photometric monitoring of small bodies of the solar system for new and refine the known parameters of potentially dangerous space bodies. Research comets is main field of interest. We use simulation for research to obtain parameters of celestial bodies. The television base observations used were in studies of meteors, which made it possible to obtain kinematic and physical parameters of meteors up to 6.0 mag.



Future Projects and Goals

     We plan to extend the photometric, spectral and morphological characteristics of comets to determine their physical properties and differences of various groups of comets. We plan also to obtain estimates the size and albedo of asteroids with help of occultation observations. We plan to examine the evolution of certain families of asteroids to assess the possibility of passing to potentially dangerous orbit by numerical calculations with modern special software. Abnormal meteors will be explored and its physical models of appearance will be offered too. This will allow refining the dynamic evolution of physical characteristics and processes of destruction of small bodies of the solar system in terms of asteroid and comet hazard.

Methodological and Technical Expertise

  • Astrometry
  • Spectroscopy and photometry of Solar System Small Bodies
  • Astronomical observational technique and methods.
