Vytautas Straižys

Vytautas Straižys (born August 20, 1936)[1] is a Lithuanian astronomer. In 1963–65 he and his collaborators created and developed the Vilnius photometric system, a seven-color intermediate band system, optimized for photometric stellar classification. In 1996 he was elected a Corresponding Member of the Lithuanian Academy of Sciences.[1] Straižys is an editor of the journal Baltic Astronomy. He is currently working at the Molėtai Astronomical Observatory. Asteroid 68730 Straizys in 2002 was named after him.

Since 2003, he is chief researcher of the same institute, Vilnius University. In 1992–93 academic year: visiting professor in Union College, Schenectady, New York.

Scientific activity

Main directions of the scientific research: multicolor photometry of stars, stellar physical parameters, stellar classification, interstellar extinction, interstellar clouds, star clusters, Galactic structure. One of the authors of the Vilnius photometric system for the classification of stars. In 1969–90 conducted the construction of the Molėtai Observatory in Lithuania and the Maidanak Observatory in Uzbekistan. Author of 324 scientific papers published in 1957–2009 and of three monographs: Multicolor Stellar Photometry (Vilnius, 1977, in Russian), Metal-Deficient Stars (Vilnius, 1982, in Russian) and Multicolor Stellar Photometry (Tucson, Arizona, 1992 and 1995, revised version, in English). In 1977–91 editor of the Bulletin of the Vilnius Astronomical Observatory, since 1992 editor of an international journal Baltic Astronomy. Scientific adviser of 22 doctoral dissertations.
