All lectures are given at 1 pm on the dates listed.

• David Moffett, Ph.D. Radio Astronomer, Furman University
  Title: Radio Expansion Studies of Supernova Remnants
  Date: June 19
  Dr. Moffett is a radio astronomy and experts on the nature of pulsars.  He will present the results that trace the dynamics of two historical supernova remnants (SNRs), SN 1006 and Tycho, for the past two decades.  Radio observations at 21-cm of each remnant were recorded in 1983-1984, 1991-1994, and 2001 to 2003 will be presented and used to measure the mean radio expansion rate of the SNRs.  The rate agrees with a previous X-ray expansion study. And for the first time, we have measured the azimuthal expansion rate over the entire rim of SN 1006.
• J. Donald Cline, President, PARI
  Title: Pieces of the Universe
  Date: June 20
  Besides being the guiding force behind the establishment of Pisgah Astronomical Research Institute, Don Cline is one of the foremost experts on meteorites.  A record of the early Solar System is contained in meteorites.  Their organic chemical composition which includes hydrocarbons and amino acids may hold keys to the problem of the origin of terrestrial life.  The origins of meteorites will be described and examples of the different types of meteorites will be presented using exhibits from Don’s extensive personal collection of meteorites. 
• Brian Dennison, Ph.D.  Radio Astronomer, University of North Carolina-Asheville
  Title: The Dedicated Interferometer for Rapid Variability (DIRV)
  Date: June 21
  Dr. Dennison is combining the two PARI 26-m radio telescopes into a single unit as a two-element interferometer. The goal of his research is to use the interferometer for a long term study of a gaseous component of the Milky Way Galaxy for which there is little known.  He will present the theory and aspects of the instrumentation needed for his work.
• Christopher S. Brown, Ph.D. Research Professor of Botany, NC State University, Director, North Carolina Space Grant
  Title: Life In Space
  Date: June 22
  Dr. Brown is an expert in microgravity biology. He will present an overview of the biology of plants, animals and humans as related to gravity and the spaceflight environment. Topics include gravitational biology, spaceflight effects on living systems, aerospace medicine, bioregenerative life support systems, and astrobiology.

• John Meriwether, Ph.D., Physicist, Clemson University
  Title: High Velocity Winds in the Thermosphere
  Date: June 25
  Dr. Meriwether measures the velocities of winds in the thermosphere by observing the Doppler shifts of oxygen lines.  He uses a series of Fabry-Perot spectrometers around the globe for his reseach.  Dr. Meriwether will describe how the instrument works, the observtaiosn he makes, and results from recent studies.
