SUMMARY:CASPER Seminar: Zdzislaw Musielak, Department of Physics, UT Arlington, "Orbital Stability of Earth-like Planets in Extra-Solar Planetary Systems"
DESCRIPTION;ENCODING=QUOTED-PRINTABLE:The existence of planets orbiting more than 400 solar-type stars is now a well-established observational result. The main technique used to detect these extra-solar planets is the cyclic Doppler shift of stellar spectral lines. This technique is most sensitive to massive planets, so most detected objects are giant (Jupiter-like) planets.  Orbital stability of Earth-like planets in stellar habitable zones is necessary for the evolution of any form of life. The results of our studies of orbital stability of terrestrial planets inside the habitable zones of single stars and in stellar binary systems with newly discovered giant planets will be presented. This study is of special interest because it can assist in the selection process of the extra-solar planetary system for current and future NASA and ESA missions aimed to search for Earth-like planets. Dr. Musielak received PhD in Physics from the University of Gdansk, Poland, in 1980. From 1980 to 1983, he was an assistant professor of astrophysics at the University of Gdansk. He left Poland in 1982 and spent one year as a visiting scientist at the Institute of Theoretical Astrophysics at the University of Heidelberg in Germany. After arriving to the United States in 1983, Dr. Musielak worked as a researcher at MIT Center for Space Research for 3 years, and then for 3 more years as a Senior NRC Associate at NASA Marshall Space Flight Center in Huntsville, Alabama. From 1989 to 1999, he was a professor at the University of Alabama in Huntsville (UAH). In 1999, he joined the faculty of the University of Texas at Arlington (UTA) as Professor of Physics and was appointed Director of the UTA Astronomy Program one year later. Dr. Musielak is the recipient of numerous teaching and research awards, including the prestigious Alexander von Humboldt Prize, Germany, received in 1997, and additional Humboldt Follow-up Research Award received in 2005.
