During the seven-year operation, some 9.37 million stellar parameters of high quality were disclosed by domestic astronomers and overseas partners, which is double the sum of other that found in other countries.
The LAMOST DR6 catalogue of stellar parameters has currently the world’s most complete sky coverage and the largest survey volume and sampling density, providing a powerful and basic data foundation for studies of the Milky Way, galaxy formation, and evolution, according to China’s national astronomical observatories.
A total of 769 clients from 124 institutions and universities in the US, Germany, Belgium, and Denmark are using LAMOST’s data for cutting-edge research. Some achievements have been made on the formation and evolution of the Milky Way, stellar physics, and special celestial search, China Central Television (CCTV) reported.
