Name: Tokovinine Andrei
I graduated from the secondary school in 1971. In 1971-1977 I was a student of the Physical Department of Moscow State University, then (1977-1980) - a PhD student at the Chair of Astrophysics of the Moscow University. The first (PhD) degree was awarded in 1980 for the thesis entited ``The potential of high angular resolution techniques in astronomy''.
I worked at the Sternberg Astronomical Institute of the Moscow University since 1980. My main scientific interests include multiple stars, astronomical instrumentation, interferometry, radial velocities, atmospheric optics and site testing. In 1980-1990 I made some 800 measurements of visual binary stars using the Phase Grating stellar interferometer of my design. In 1985 I built the correlation radial velocity echelle spectrometer and started the statistical survey of nearby K and M dwarf stars for binarity. This work was accomplished in 1991 and formed the basis of the second thesis (``Studies of binary stars in the solar neighbourhood''), the DrSci degree awarded in 1992. In 1997 I published the first catalogue of multiple (i.e. triple, quadruple etc.) stars. Presently I pursue several projects related to the study of multiple stars: discovery and study of close sub-systems from radial velocity data (some 30 new orbits are published), speckle-interferometry, CCD and adaptive optics imaging.
In the field of atmospheric optics, I participated in numerous site testing missions in the Central Asia in the 1980-s, making seeing measurements with the shearing interferometer of my design. Since 1991 I developed in collaboration with the Nice University a novel instrument, GSM (Generalized Seeing Monitor) for advanced measurements of the optical turbulence. Several successful measurement campaigns with this instrument were accomplished, including the ESO La Silla observatory (1997), the Gemini-South site in Chili (1998) and the Paranal VLT observatory in Chili (1998). Thus, for the first time a solid statistical data on the turbulence outer scale were obtained. A theoretical work on a scintillation turbulence profiler (in collaboration with ESO) is in progress, and has already resulted in the measurements of high-altitude turbulence above the Maidanak observatory.
My practical experience includes computation of the orbits of binary stars, processing of adaptive optics and corongraphic images (in IRAF or MIDAS environment), building a fiber-fed echelle CCD spectrometer and some other instruments.
About 90 papers have been published in the refereed journals in the period 1974-2000, plus several reports in the conference proceedings and two books: ``Stellar Interferometers'' (1986, in Russian) and ``New imaging methods in astronomy'' (1990, a review). Since 1979 I have been participating in the teaching activity of the Chair of Astrophysics of Moscow University (lectures on high-resolution techniques, direction of graduate and PhD students).
I am a member of the International Astronomical Union (Commissions 26 and 30), and actually a president of IAU Commission 30 (Radial Velocities). I am also a member of the Editorial Board of the journal "Pis'ma v Astronomicheskii Zhournal" ("Astronomy Letters") since 1994.
My long-term stays in other countries have been: Mount Stromlo Observatory (Australia, 1988, 3 months), Nice University (France,1991, 6 months as associate professor), Grenoble Observatory (France, 1994-1996, 3x4 months on the PAST position, processing of adaptive optics images), Lyon Observatory (France, 1998-1999, 1 year; development of a seismometer for real-time telescope vibration correction for Polychromatic Laser Guide Star project), European Southern Observatory (Garching bei München, 2000, work on Multi-Conjuhate Adaptive Optics). Since February 1, 2001, I work as an Associate Astronomer at the Cerro Tololo Inter-American Observatory in Chile.
I married in 1976 and have two sons, born in 1978 and 1981.
