Baylor University's Center for Astrophysics, Space Physics and Engineering Research (CASPER), the Office of Vice Provost for Research and the Institut für Raumfahrtsysteme will host Dr. Hans-Peter Roeser, director of the Institute of Space Systems at the University of Stuttgart in Germany.

The event, which is free and open to the public, will showcase Roeser's lecture, "A New View on Superconductivity and Superfluidity," at 3:30 p.m., Tuesday, April 6, in room C.206 at the Baylor Sciences Building (BSB) on the Baylor campus. A reception for Roeser will be at 2:45 p.m. on the second floor of E hall of the BSB

Roeser has found a "simple connection" between crystal geometries and the activation temperatures of high temperature super conductors. Superconductors are rare materials in which electrical resistance disappears suddenly and almost fully when cooled to certain temperatures. The activation temperatures are dependent on the material property and can change with the introduction of pressure or internal magnetic fields.

"Superconductivity also hold great promise from the perspective of Space travel," Roeser said. "Because a greatly reduced electrical resistance means at the same time an increase thermal conductivity."

Roeser's main interests are in the development and application of remote sensing instruments in the visible and infrared wavelength range for airborne and space-borne models. Since 2002, Roeser has been a professor at Stuttgart and managing director of the Institute of Space Systems. He received his bachelor's and doctorate from the University of Bonn in Germany and worked for 20 years at the Max-Planck-Institute for Radioastronomy, where he has held a number of positions. He served as the German spokesman of the US-German Stratospheric Observatory, also known as "SOFIA", which is a Boeing 747 with a 2.7 m telescope on board. He has authored more than 70 papers in international journals, more than 80 papers in conference proceedings and has received several prestigious international awards in physics and engineering.
