Common-envelope systems: progenitors, mergers and survivors (a symposium during EWASS 2020).

The goal of the proposed symposium is to discuss the latest advances in the study of CE evolution in the context of stellar mergers and related phenomena. The meeting will combine observations and theory to probe where we stand in solving the problem of the CE and define avenues of future research in the field.

Topics: stellar mergers and CE transients , post-CE objects (central stars of planetary nebulae, cataclysmic variables, etc.) and merger remnants: blue and red strugglers, anomalous Cepheids, Be & B[e] stars, η Car, FK Com stars, etc. hydrodynamical modeling of the common envelope , common envelope evolution in population synthesis , radiation transport and shocks in the common envelope phase
