报告摘要：

～～～～～～～～～～～～～

I will discuss the primary challenge of practical asteroseismology—the difficulties in detecting and identifying high-degree, non-radial, small-scale modes and outline methods for overcoming this issue. I will report on the results of my spectroscopic survey of the search for and study of non-radial pulsations in bright, rapidly rotating A-type stars, pulsating components of eclipsing binaries, and stars with exoplanets.

报告人简介： 

David is a globally recognized authority expert in studying pulsating mass-accreting components in semi-detached eclipsing binary systems, particularly the oscillating Eclipsing Algol (oEA) stars - a class he originally discovered and classified. He has worked in several international astronomical organizations, including the National Astronomical Research Institute of Thailand (NARIT), the Astrophysical Research Center for Structure and Evolution of Cosmos (Sejong University, South Korea), the Crimean Astrophysical Observatory (Ukraine), and the Astronomical Observatory of Odessa National University (Ukraine). He has led or organized numerous international research and projects, including photometric and spectroscopic observations of pulsating stars, asteroseismology, exoplanets, and more.
