Context: This workshop aims to bring together state-of-the-art multi-wavelength observations, theory and modelling of winds in multiscale astrophysical systems, from single objects to accreting systems (binary systems, protoplanetary discs, AGNs…). Winds are present in many astrophysical objects and can play a crucial role in their evolution and strongly impact their environment.
X-ray observatories (e.g. XMM-Newton, Chandra, NuSTAR, NICER), ground- and space-based optical/NIR facilities (e.g. VLT, TNG, Gemini, Gaia), UV/optical space telescopes (e.g. IUE, Hubble) and the current radio instruments (e.g. MeerKAT, LOFAR) provide complementary diagnostics of winds, stellar ages, kinematics, compositions and circumstellar material. Recent high-resolution data from observatories like XRISM, ALMA and JWST are providing unprecedented constraints on wind properties and launching processes. Upcoming facilities such as ELT, NewAthena and SKA, where the French community plays a significant role, and recent development in numerical and statistical methods are expected to provide unique advances in the near future.
Objectives: The complexity of the data has highlighted the need for coordinated, multi-wavelength approaches that bring observers and theorists into closer collaboration. Building on French expertise across AT-PS, -PEM, -CG, and -PCMI (that are supporting this session), this workshop will foster such cross-community efforts. Presentations of state-of-the-art multi-wavelength observations, theory and modelling of winds across the stellar lifecycle – from birth (young stellar objects and protoplanetary discs), through main-sequence and binary evolution, to endpoints (XRBs) – and on to AGNs will be given. Our goal is to understand how mass, momentum and metals are launched, transported and recycled, and how these processes shape planetary formation processes, large-scale structures, and galaxy evolution.
