David Polishook

			I am a planetary scientist and astronomer, studying the physical nature of asteroids, their evolution with time, and the applications of these to Solar Systems formation and the safety of the Earth’s inhabitants. I am an AXA post-doctoral fellow at MIT’s Department of Earth, Atmospheric and Planetary Sciences working in the group of Prof. Richard P. Binzel. I received my PhD from Tel-Aviv University, Department of Geophysics and Planetary Sciences under the guidance of Prof. Dina Prialnik and Dr. Noah Brosch. June 2014: A new study finds that asteroid pairs have rubble-pile structure and the YORP effect modified their spin axes before fission – paper accepted to Icarus. More details here. Research Interests: - Near-Earth Asteroids close flybys. - Asteroids disintegration by rotational fission into separated pairs and binaries. - Thermal forces that modify asteroids (Yarkovsky and YORP effects). - Space Weathering of atmosphere-less bodies. - Mining Astronomy data through surveys and archives.
