Binary Stars in a New Era

Binary Stars in a New Era Conference 2025

This conference, organised by the Yunnan Observatories (CAS), will be held from 24 to 30 August 2025 in Lijiang, Yunnan Province, China

Binary stars lie at the heart of many key astrophysical phenomena. Various explosive cosmic events result from binary stars, as do close double black holes/neutron stars/white dwarfs, type Ia supernovae, X-ray binaries, millisecond pulsars etc. Relying on existing large scientific facilities, classical optical, radio and X-ray observations are discovering increasingly large numbers of such binary stars. A decade ago, the ground-based LIGO/Virgo detected the merging of two stellar-mass binary black holes, opening a new window in gravitational wave astronomy. In the future, with the support of next-generation astronomical instruments, we shall discover many more binary-related celestial objects. Against this backdrop, we convene this conference, inviting all international observers and theoreticians in the field of stellar science to participate in and exchange recent progress related to binary stars and to look forward to future collaboration and development of new directions for research.

Conference topics:

1. Binary star interactions: from mass transfer to common envelope evolution.

2. Supernovae: from progenitor modeling to explosion simulation.

3. Gravitational wave sources: from double black holes to white dwarfs.

4. Exotic stars: X-ray binaries, binary pulsars, luminous red novae, hot subdwarfs, cataclysmic variables, symbiotic stars, etc.

5. Binary population synthesis studies on binary objects.

6. Binary star observations from large facilities: Gaia, TESS, LAMOST, JWST, FAST, etc.
