SCHEDULE: NOV 12-18, 2011

When viewing the Technical Program schedule, on the far righthand side is a column labeled "PLANNER." Use this planner to build your own schedule. Once you select an event and want to add it to your personal schedule, just click on the calendar icon of your choice (outlook calendar, ical calendar or google calendar) and that event will be stored there. As you select events in this manner, you will have your own schedule to guide you through the week.

You can also create your personal schedule on the SC11 app (Boopsie) on your smartphone. Simply select a session you want to attend and "add" it to your plan. Continue in this manner until you have created your own personal schedule. All your events will appear under "My Event Planner" on your smartphone.

Study of the Moon-Solar Wind Interaction with Parallel Kinetic Plasma Simulations

SESSION: Research Poster Reception

EVENT TYPE: ACM Student Research Competition Poster, Poster, Electronic Poster

TIME: 5:15PM - 7:00PM

SESSION CHAIR: Bernd Mohr

ROOM:WSCC North Galleria 2nd/3rd Floors

ABSTRACT:
The interaction of the solar wind with unmagnetized astrophysical bodies, such as the moon, is quite different from that with magnetized bodies such as the Earth. This is because electric charge accumulate on the dayside surface of unmagnetized bodies while a wake tail is formed on the nightside. When the size of an astrophysical body and/or its magnetosphere is comparable to the ion gyro radius, ion kinetics plays a role for the global structure and dynamics of its electromagnetic environment. Fully kinetic plasma simulations, such as Vlasov and particle-in-cell (PIC) simulations, are essential approach to treat both electric charged accumulation/separation and ion gyro motion simultaniously. In the present study, we are developing parallel Vlasov and PIC codes for studying the electromagnetic environment due to the interaction between the Moon and the solar wind, which may scale more than 10,000 cores.
