Tsevi Mazeh is Professor of Physics & Astronomy at Tel Aviv University, where he has served as researcher and lecturer since 1979.
Throughout his career Prof. Tsevi Mazeh has functioned as both theorist and observer. Early on, as far back as his graduate student days at the Hebrew University of Jerusalem, Mazeh became interested in the dynamics of interacting multi-body stellar systems. His PhD dissertation was a theoretical study of the ``induced eccentricity" of an inner stellar binary-pair by a distant bound perturber star. This effect has been observed not only in binary stars, but also in the evolutionary dynamics of the recently discovered planetary systems. Mazeh's early interest and expertise in stellar dynamics played a crucial role in the discovery of extra-solar planets.
In 1984 Mazeh initiated the first ever "radial-velocity" search for extra-solar planets in pursuit of his paradigm-shaking hypothesis that massive planets could exist close to their parent stars, at that time widely believed to be impossible. Mazeh's observations, carried out with Dave Latham (Harvard) and in cooperation with Michel Mayor (Geneva) provided the breakthrough discovery in 1989 of the first known massive candidate for extra-solar planet HD114762b. In 2000, Mazeh led the research and discovery of the planet around the star HD209458, enabling its subsequent detection as the first known transiting (eclipsing) planet.
Mazeh is leading an international effort to detect planets and brown-dwarfs by novel relativistic effects. This research is supported by a highly prestigious 2M euro Advanced Grant awarded to Prof. Mazeh by the European Research Council (ERC) in 2010. Mazeh's team has already detected the first known relativistic beaming planet – Kepler 76.
Prof. Mazeh is a popular writer and public speaker on Astronomy, History of Science, and Science and Religion. He published a book "Introduction to Special Relativity" (2005); Edited, together with Pinchas Leizer, Drishat Shalom - Reading Peace and Justice in the Torah (2010). Hr chaired the left-wing political movement "Netivot Shalom" for five years.
