Follow us on Twitter: @BaylorUMediaCom

Baylor University's Center for Astrophysics, Space Physics and Engineering Research (CASPER) will host a seminar featuring Dr. Mark Lewis, associate professor of computer science at Trinity University, at 1:30 p.m. Friday, Oct. 1, in room D110 of the Baylor Sciences Building on the Baylor campus.

CASPER hosts seminars with different speakers on Friday afternoons throughout the semester. The events are free and open to the public.

Lewis will discuss Saturn's rings and how negative diffusion can work to maintain narrow features in perturbed rings. He will show the results of several numerical simulations that show how effective negative diffusion is in different situations.

Lewis has been working in the area of numerical simulation of planets since his doctoral work in the late 1990s. He specializes in N-body simulations of collisional and gravitational systems.

Other CASPER speakers this semester include:

' Dr. Kristina Lynch, Dartmouth College, on Friday, Oct. 8
' Dr. Gregory Earle, University of Texas at Dallas, on Friday, Oct. 29
' Dr. Ralf Srama, MPI Heidelberg/University of Stuttgart, on Friday, Nov. 5
' Dr. Rainer Saundau, IAA Paris/ DLR Berlin, on Friday, Nov. 12
' Dr. John Fitch, Birkeland Current, on Friday, Nov. 19

All of the seminars are held at 1:30 p.m. in room D110 of the Baylor Sciences Building.
CASPER is an official Baylor research center formed by a partnership between Baylor and Texas State Technical College-Waco. Space research within CASPER has a proud heritage dating back to the 1960s, including flight projects from Explorer I forward. Personnel within the Center have been actively involved on a number of NASA and ESA flight missions.
