On April 14–18, 2025, the ISSI-BJ Workshop “Space-based Stellar Astrophysics in the Ultraviolet” was held successfully. About 50 leading scientists from a range of institutes took part in the event, which was convened by Profs. Martin Barstow (Leicester University, UK), Peng-fei Chen (Nanjing University, China), Richard de Grijs (Macquarie University, Australia; ISSI-BJ, China), Ana I. Gómez de Castro (Complutense University of Madrid, Spain), Li Ji (Purple Mountain Observatory, Chinese Academy of Sciences, China), Chao Liu (National Astronomical Observatories, Chinese Academy of Sciences, China), and Annapurni Subramaniam (Indian Institute of Astrophysics, Bangalore, India). 

The Workshop’s main topics encompassed stellar astrophysics in the ultraviolet; the Sun and stellar nucleosynthesis at ultraviolet wavelengths; accretion and outflows in the ultraviolet; ultraviolet radiation fields in stellar environments; transients and stellar activity as revealed by ultraviolet diagnostic tracers; star clusters in the ultraviolet; the impact of UV radiation on astrobiology; and synergies with modern UV ground-based and space-borne observatories.

As scientific output, a new volume of the Space Science Series of ISSI will be published covering the content of this Workshop, for distribution to both the science community and space science institutions.
