Mirek (Miroslav) Plavec, prominent stellar astrophysicist who conducted essential studies of mass transfer within strongly interacting binary systems, died on 23 January 2008 at his home in Pacific Palisades, California. Plavec received his Ph.D. in astronomy from Charles University in Prague in 1955. After thirteen years working in his native Czechoslovakia, he and his family emigrated to the United States, where he took up a post at UCLA. There he continued his research and taught astronomy for over 25 years.
