Brief Biographical Information:

Dr. Nakamura graduated from the Graduate School of Science and Technology of Kobe University under Prof. Tadashi Mukai in 1996 and held a position as a research associate at the Information Processing Center of Kobe University during the Leonid MAC 1998 mission. As of April 2000, Dr. Nakamura has moved to the Earth Observation Research Center of NASDA, Japan.

Current Research:

His main research interests are the origin and evolution of the solar system and observations of small bodies in the solar system. Notably, he has worked on in-situ imaging of asteroids, Martian satellites and the moon, ground-based observations of minor bodies in our solar system, and theoretical studies of circumstellar dust disks. He has worked on the optical properties of dust grains. Important for the Leonid MAC mission, he has acquired considerable expertise with the use of CCD imagers for precise measurements of faint diffuse glows, being able to discern the zodiacal dust bands from the background zodiacal light in scattered visible light.

Research on Leonid MAC:

Nakamura will head a conserted effort to study the faint glow of dust particles in the Leonid meteoroid stream that might be seen when the Earth crosses the dust trail of comet 55P/Tempel-Tuttle. For that, his team will image the true radiant position of the Leonid shower in a direction where the line of sight is along the meteoroid stream.

Results of this work are described here.
