Numerical simulations have become a major tool for understanding galaxy formation and
evolution. Over the decades the field has made significant progress. It is now possible to …

Although fundamental for astrophysics, the processes that produce massive stars are not
well understood. Large distances, high extinction, and short timescales of critical …

We compile observations of early-type binaries identified via spectroscopy, eclipses, long-
baseline interferometry, adaptive optics, common proper motion, etc. Each observational …

A comprehensive census of the stellar content of the OB associations within 1 kpc from the
Sun is presented, based on Hipparcos positions, proper motions, and parallaxes. It is a key …

This book discusses in detail all the relevant numerical methods for the classical N-body
problem. It demonstrates how to develop clear and elegant algorithms for models of …

We perform an extensive numerical study of the evolution of massive binary systems to
predict the peculiar velocities that stars obtain when their companion collapses and disrupts …

We introduce TIGRESS, a novel framework for multi-physics numerical simulations of the
star-forming interstellar medium (ISM) implemented in the Athena MHD code. The …

The high-precision astrometry from the second data release of the Gaia mission has made it
possible to greatly improve the census of members of nearby clusters and associations. I …

Black hole binaries formed dynamically in globular clusters are believed to be one of the
main sources of gravitational waves in the Universe. Here, we use our new population …

We use milli-arcsecond accuracy astrometry (proper motions and parallaxes) from
Hipparcos and from radio observations to retrace the orbits of 56 runaway stars and nine …
