MAUVE : A UV-Vis spectroscopy facility dedicated to studying the magnetic activity of active stars

MAUVE is a small space mission by Blue Skies Space mainly dedicated to investigating the stellar magnetism of active stars (across a broad spectral range from F- to M-type stars). This concept is particularly of interest in the context of stellar systems hosting exoplanets, where the magnetic activity of the host star can substantially impact the atmosphere of exoplanets located within their habitability zone. MAUVE offers a broad wavelength range from NUV to VIS (200-700 nm, R~30-100), and will monitor 1000+ K- and M-dwarfs (ranging from less than an hour to long-term monitoring depending on the targets’ coordinates). This category of stars not only includes the best candidates for discovering exoplanets (due to their unique features), but also comprises the prime exoplanetary host candidates harboring life.

K- and M-dwarfs are particularly active stars and flare frequently, which in turn can either erode exoplanetary atmospheres, or intrigue prebiotic chemistry and initiate life on them. MAUVE strives to provide the very low resolution spectra of these complex events in UV and VIS spectral ranges, and contribute to the previous photometric studies of flares performed by Kepler and TESS in white light.

This unique opportunity thus not only adds a brand new dimension to the studies of flaring stars, but also enables investigating the simultaneous magnetic diagnostics of stars during this transiting phenomenon.
