Over the past twenty years, photometry has undergone a revolution thanks to space-based missions including CoRoT, Kepler and TESS and will continue to improve with the launch of PLATO in 2026. The significant improvement in photometric precision and temporal baseline has led to a transformation in the fields of asteroseismology and binary star science. Specifically, as multiple star systems provide unique benchmarks for asteroseismology and because pulsations can both affect and be affected by an orbiting stellar companion, the combination of these two fields has provided extensive insight into many areas of astronomy, including stellar evolution and tidal theory.

To date, stellar science meetings have predominantly focused on either asteroseismology, or binary star science. The importance of pulsating stars in binary systems has been highlighted by the growing number of publications in the field. Symposium S8 is thus dedicated to the emerging field of asteroseismology in multiple-star systems. The purpose of this symposium is to enable experts in the currently distinct fields to foster collaborations and coordinate efforts. We invite the community to submit abstracts for oral and poster contributions.

Programme

The symposium is composed of six sessions. The first session will be dedicated to reviewing binarity and asteroseismology from both a theoretical and observational perspective (3 talks total). The remaining five sessions will have one or two invited speakers for short review talks. The remaining time will be devoted to contributed talks and posters.

• Review session
• Spectroscopy and astrometry: radial velocities, atmospheric parameters
• Main sequence pulsations in binary systems: solar-like, delta Scuti, gamma Doradus
• Multiple star systems as asteroseismic calibrators
• Interactions in close binary systems
• Post-main sequence pulsations in binary systems: red giants, subdwarf B stars, white dwarfs

• Review talks: 23 + 5 min for questions
• Invited talks: 16 + 4 min
• Contributed talks: 12+2 min
• e-posters: 2 min
