Binary stars: observation and theory

Principal contact: J. Southworth (

Organisers: H. Bruntt (Paris Observatory, France), R. Izzard (Utrecht, The Netherlands), J. Southworth (Warwick, UK)

Binary stars present a huge variety of opportunities, from forensic probes of stellar evolution and high-precision distance measurements, to exhibitions of many weird physical phenomena. These sessions will showcase the cutting edge of binary star studies, from high-precision parameter determinations of visually resolved or eclipsing systems to studies of stellar remnants, substellar objects, accretion processes, magnetic phenomena, and violent eruptions such as novae and Type 1a supernovae. An equal emphasis will be placed on observational studies of binary star systems and the theoretical understanding of the physcial processes which govern their evolution.
