报告摘要：

～～～～～～～～～～～～～

Mauve is a small satellite equipped with a 13-cm telescope and a UV-Visible spectrophotometer (with an operative wavelength range of 200-700 nm) conceived to measure the stellar magnetic activity and variability. It is scheduled for launch in October 2025 and is currently under construction. The Mauve science program will be delivered via a multi-year collaborative survey program, with thousands of hours each year available for long baseline observations of hundreds of stars, unlocking a significant time domain astronomy opportunity. Mauve’s mission lifetime is 3 years with the ambition of 5 years, and will cover a broad field of regard (–46.4 to 31.8 degrees in ICRS) during this period.

This facility was conceived to support pilot studies and new ideas in science and is fully dedicated to time-domain astronomy. The main surveys to be executed by Mauve are long baseline observations of flare stars, Herbig Ae/Be stars, exoplanet hosts, as well as contact binary variables (RS CVn variables, symbiotic stars, Algol-type stars, etc.). Besides these major science themes, the spectrometer data can be utilised to support and complement existing and upcoming facilities as a pathfinder, or conduct simultaneous/follow-up observations.
