China’s Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) released its latest dataset on Tuesday, providing over 30 million spectra to domestic and international astronomers.
The dataset, named DR13, covers observations from October 2011 to June 2025, including 6,961 low-resolution and 3,404 medium-resolution observation patches. It also contains a stellar spectral parameter catalog with approximately 12.94 million entries.LAMOST continues to lead the world in the total number of released spectra, enabling over 1,900 users from 278 institutions across multiple countries to publish more than 2,200 high-quality research papers.
The telescope’s data has contributed to over 300 papers annually, with more than 40 percent authored by foreign astronomers. LAMOST’s spectra allow for systematic research on the Milky Way, compact objects, stellar physics, exoplanets, and quasars.Operating efficiently for 14 years, LAMOST is China’s first major national scientific infrastructure in astronomy, pioneering large-scale spectroscopic sky surveys and facilitating breakthroughs in global astronomical research.
