This week we are delighted to be hosting over 200 participants at DAD2021, the ‘Distorted Astrophysical Discs’ online workshop.

Recent high-resolution observations of nearly-Keplerian discs in a variety of astrophysical systems – protoplanetary discs, discs around compact objects, discs within and around binaries - have revealed a stunning richness of asymmetric and non-coplanar distortions: spiral arms, eccentricities, warps, azimuthal clumping, and so on. These omnipresent deviations from a classical planar and circular shape have important implications for their dynamics, as well as for the formation and evolution of objects inside and around them. The goal of the DAD2021 workshop is to bring together researchers working on non-axisymmetric distortions and warps in protoplanetary discs, galactic discs, discs in binaries, circumbinary discs, debris discs around white dwarfs, planetary rings, tidal disruption events, and so on, to enable focused discussion on the emerging puzzles and recent progress made in understanding such distortions. This forum will provide a venue for the exchange of ideas between theorists and observers from different fields and will cover both recent advances in the theory of non-axisymmetric and non-coplanar structures in discs and observational discoveries using new instruments (e.g. ALMA) and techniques.
