“Two in a Million” - The Interplay between Binaries and Star Clusters: Second Announcement

Published: 04 May 2023

The conference “Two in a million” - The interplay between binaries and star clusters will be held at ESO Garching, Germany, between 11-15 September 2023. Both in-person and online participation will be possible. Please note that the list of invited speakers has been updated.

A substantial fraction of cosmic star formation happens in star clusters, and binary populations residing in extreme cluster environments are fundamentally different from those in galactic fields. Each binary in a star cluster will evolve through a multitude of interactions with other cluster members. A better understanding of this evolution is required to answer some of the most pressing questions in modern astrophysics, from the origin of black-hole mergers to the characterization of galaxies in the early Universe. Historically, star clusters have always been cornerstones for our knowledge of stellar evolution. With this workshop, we aim to continue this legacy by establishing them as cosmic probes for binary studies. The workshop intersects four main fields of modern astrophysics: star formation, stellar and binary evolution, star clusters and their dynamics, and gravitational wave astronomy. With this scientific overlap, the workshop wants to bring scientists of all of these fields together and facilitate the scientific exchange that will lead to new insights and scientific breakthroughs.
