Main Topics of the Conference

Importance of Binaries

• Fundamental stellar parameters
• Cosmic distance ladder
• Impact on stellar populations

Interacting binary systems

• Symbiotic stars, classical novae, contact binaries
• Mass transfer and outflow, accretion and colliding winds

Pulsations in binaries and active binaries

• Magnetic spot cycles, flares, granulation effects
• Pulsating components, tidally-excited pulsations, calibrating asteroseismology

Binary star evolution

• Post-common-envelope binaries and common-envelope evolution, Darwin instability, stellar mergers, blue stragglers, binaries with compact components
• Perturbations in close binaries

Multiple systems

• Multiply eclipsing stars
• Dynamical perturbations, stability of the systems, Kozai-Lidov cycles
• Origin and evolution
• Circumbinary exoplanets

Modeling

• New modeling software/new features
• Data treatment/preparation
• Modeling of eclipsing binary observations in the era of satellite data
• Common modelling tools of binaries and exoplanets

Observations

• Multi-dataset modelling
• Surface imaging
• Radial velocities, spectral fitting and disentangling
• New space missions and ground-based telescopes
• Binary stars in the upcoming exoplanet missions
