Description

Title: Overview of the LAMOST-Kepler project and the 1.93-m telescope of BNU 

Speaker: Jianning Fu 

 
Abstract: The NASA Kepler Space Telescope continuously monitored the Kepler field from 2009 to 2013, and then observed 20 K2 sky regions along the ecliptic from 2014 to 2018. It obtained unprecedented, almost continuous, ultra-high precision light curves for a large number of stars, making revolutionary breakthroughs in research on exoplanets and stellar physics. However, the lack of reliable stellar atmospheric parameters for these stars affects and restricts the in-depth scientific application of Kepler photometric data. Hence, we launched the LAMOST-Kepler project in 2011, with the aim of using LAMOST to observe low resolution spectra of large sample stars in the Kepler field, initialized low resolution spectroscopic observations for 15 K2 sky regions using LAMOST in 2015, and started a time-domain medium resolution spectral survey of 20 LAMOST fields of view in the Kepler and K2 fields in 2018. 

 

In this report, I shall introduce the motivation and scientific objectives of the LAMOST-Kepler project, the survey strategies, the observation progress and data processing, the derived stellar atmospheric parameters and radial velocity measurements, and the scientific applications of the data in the research fields of stellar pulsations and asteroseismology, exoplanets, stellar magnetic activity and flares, peculiar stars and structure of the Milky Way, and binary stars. Finally, an introduction will be given to the 1.93-m telescope of Beijing Normal University which is going to be built at the Muztag-Ata site in Xinjiang. 

 

 
Bio: He graduated from the Department of Physics of Peking University in 1987 with a bachelor's degree. In 1997, he received a doctor's degree from Beijing Astronomical Observatory of Chinese Academy of Sciences. From 1998 to 2005, he successively engaged in scientific research at Observatoire Midi-Pyrénées in France and University of Brussels in Belgium. In 2005, he was introduced to the Department of Astronomy of Beijing Normal University as a professor. He was selected into the New Century Excellent Talents Program of the Ministry of Education of China in 2007. In 2015, he was chosen as an outstanding scholar of the national major scientific facility LAMOST. 

 

Academic background: 

       His main research areas are stellar pulsations and asteroseismology. He has published over 190 academic papers, including 130 articles in SCI journals. He hosted the general, key, and major projects of the National Natural Science Foundation of China. He is a member of the International Astronomical Union, a member of the Chinese Astronomical Society, a member of the expert group on space astronomy and astrophysics of China's Manned Space Engineering, an associate director of the Science Center of the National Astronomical Observatory of China's Space Station Survey Telescope; a member of the Science Committee and the head of the Medium Resolution Spectral Survey Working Group of the national major scientific facility LAMOST, a member of the Strategic Planning Committee of Xinjiang Astronomical Observatory of Chinese Academy of Sciences; a review expert of the National Development and Reform Commission, the Ministry of Science and Technology, the National Natural Science Foundation of China and the Chinese Academy of Sciences.
