Lunch Session LS11  13 July 2023

Evolving Observations of Binary Stars Reveal Photoplanetary Discs, Circumbinary Planets, Transients, and Mergers

News: The conference registration and submission of papers is open now.

  • Posters are also welcome for this session.
  • The full list of invited speakers is now complete.
  • Contributed papers for this session may be submitted on the page of registration.

Aims and scope

Questions we aim to address in this special session are: How do exoplanets and close binary stars form from the same protoplanetary disc? How do exoplanetary systems in such constricted systems subsequently evolve? How can planets? orbits remain stable in the evolution of the binary?

In this special session, we will have rich discussions and/or emerging ideas on exoplanets in close binary stars, from formation to death.

Programme

  • Architectures of exoplanet(s) in compact binary systems
  • Exoplanet and binary star formation in common protoplanetary discs
  • Circumbinary exoplanets in close binaries
  • Information Algols yield on common envelope phase
  • Insights from Kepler, Alma, Tess, JWST, and Gaia observations of Algols, CVs, and compact binaries with exoplanet(s)
  • ALMA observations of protoplanetary discs in binary systems

Invited speakers

  • VLBA Architecture of GJ 896AB Compact Binary with Exoplanet, Gisela Ortiz-León, UNAM and the Max Planck Institute GERMANY
  • Common Envelope Evolution and Triple Dynamics as Pathways to form Gaia 0007-1605, Felipe Lagos-Vilches, University of Warwick UK
  • Precession and Polar Alignment of Accretion Discs in Triple Stellar Systems, Simone Ceppi, University of Milan IT
