BEIJING, March 25 (Xinhua) — China's Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) on Tuesday released its latest dataset, including more than 30 million spectra, to domestic astronomers and international collaborators, cementing its position as the research project with the largest number of published spectra worldwide.
The dataset, named DR13, covers the observation period from October 2011 to June 2025 and includes 6,961 low-resolution observations and 3,404 medium-resolution observations, according to the LAMOST Operation and Development Center of the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC).
The published 30.82 million spectra include approximately 13.47 million low-resolution spectra and 17.35 million medium-resolution spectra. The dataset also includes a catalog of stellar spectral parameters containing approximately 12.94 million records.
According to NAOC, the total number of spectra published by LAMOST and the scale of its stellar parameter catalog continue to hold world-leading positions.
To date, more than 1,900 researchers from 278 research institutions in various countries and regions, including China, the United States, Germany, Belgium and Denmark, have conducted research using data obtained from LAMOST, resulting in the publication of more than 2,200 high-quality scientific papers.
In recent years, LAMOST data have been used to publish over 300 scientific papers annually, with over 40 percent of these being written by international astronomers. Based on its overall scientific output, LAMOST ranks among the world's leading large astronomical telescopes in the 6- to 10-meter class.
As China's first major national astronomy research and development facility, LAMOST pioneered global, large-scale spectroscopic sky surveys and has been operating efficiently and reliably for 14 years. The spectra obtained through this project have enabled astronomers worldwide to conduct the most systematic studies to date of the structure and evolution of the Milky Way, and have led to several breakthroughs in fields such as the search for compact objects, stellar physics, exoplanets, and quasars. -0-
