Andrew Poppe: Plasma Physics of the Lunar Surface

May 18, 2010 @ 9:00 am PDT

Andrew Poppe will be the seventh speaker in NLSI’s Director’s Seminar Series. He will be speaking on observed lunar dusty plasma phenomena, with Plasma Physics of the Lunar Surface.

Plasma Physics of the Lunar Surface

OVERVIEW:

The lunar environment is a rich natural laboratory for the study of plasma processes that occur throughout the solar system. As an airless body, the surface of the Moon is directly exposed to the streaming solar wind flow, which gives rise to several phenomena, including: (1) the formation of a photoelectron sheath on the dayside and a kinetic sheath on the nightside; (2) the interaction of the solar wind with lunar mini-magnetospheres; and (3) the formation of the lunar wake and void. As Earth’s nearest example of a surface-bounded exosphere (SBE), the Moon is a relatively easy body to access, yet investigations to date have not fully measured and explained all relevant plasma processes at the Moon. Poppe will discuss past, present and future measurements and models of the lunar plasma environment. Further investigations can help scientists understand the plasma physics not only at the lunar surface, but also at a multitude of other bodies throughout the solar system, including Mercury, asteroids and airless moons (Ganymede, Phobos, Deimos, etc.).

SPEAKER BIO:

Andrew Poppe is a fourth-year graduate student in physics at the University of Colorado. He research includes simulation of the lunar photoelectron sheath with particle-in-cell code in order to understand observed lunar dusty plasma phenomena. In addition to his lunar simulations, he also works on the Student Dust Counter on the New Horizons mission, NASA’s first satellite to the Pluto-Charon system.
