嘉宾简介:
Dr. Xianming Han is a professor at the Dept. of Physics and Astronomy, Butler University, Indianapolis, Indiana, USA, and served as its Chairman from 2008 to 2017. He is also a member of the SARA (Southeastern Association for Research in Astronomy) Telescope consortium. He received his B.S. from University of Science and Technology of China, and Ph.D. from University of Colorado, Boulder, Colorado, USA. His current research interests are in eclipsing binary star systems, asteroids, supernovae.
报告摘要:
Most stars are actually in pairs or triplets. Observing binary stars helps develope stellar evolution theories. If their orbital plane of a binary star system is more or less parallel to the light of sight, one star will block the other as they orbit around each other. This is known as eclipsing binary.
In this talk, we will discuss observations of eclipsing binary star systems and what information we can extract from their lightcurves. We will also discuss observations of Jovian satellites and asteroids using our SARA (Southeastern Association for Research in Astronomy) and Holcomb telescopes.
