Many astronomical events occur on timescales of minutes, hours, and days, such as stellar pulsations, stellar flares, and exoplanet transits. Continuous photometric monitoring is necessary to detect these astronomical events and to study their physical mechanism and evolution over time. The Kepler space telescope, for example, has detected a wide variety of exoplanets, changing our view of the universe. In addition to detecting exoplanets, TESS is also contributing to the research field of astroseismology. Time domain astronomy can also be studied with the help of ground-based telescope surveys. This presentation will combine the author’s research experience, including processing data from the telescopes in Antarctica, and participating the construction of Time Domain Observatory in the west of China. Some time-domain astronomical sciences of ground-based telescopes will be discussed, including exoplanets, binaries, stellar flares and pulsations.
Ming Yang (杨明) is an associate researcher at Nanjing University. He holds a PhD in astrophysics from Nanjing University, and has gained his scientific and teaching experience through participating some projects led by the exoplanet research group of Nanjing University. His research fields include (1) detecting exoplanets and studying their formation and evolution, (2) eclipsing binary stars and pulsating variable stars, (3) celestial mechanics and N-body simulation.
