Stellar multiplicity is a ubiquitous outcome of the star-formation process. The frequency and
main characteristics of multiple systems, and their dependence on primary mass and …

▪ Abstract Stellar clusters are born embedded within giant molecular clouds (GMCs) and
during their formation and early evolution are often only visible at infrared wavelengths …

A universal initial mass function (IMF) is not intuitive, but so far no convincing evidence for a
variable IMF exists. The detection of systematic variations of the IMF with star-forming …

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 …

Context. The fraction of binary stars is an important ingredient to interpret globular cluster
dynamical evolution and their stellar population. Aims. We investigate the properties of main …

We present results from the largest numerical simulation of star formation to resolve the
fragmentation process down to the opacity limit. The simulation follows the collapse and …

Aims. We take advantage of the second data release of the Gaia space mission and the
state-of-the-art astrometry delivered from very long baseline interferometry observations to …

We present a high spatial resolution multiwavelength survey of 44 young binary star systems
in Taurus-Auriga with separations of 10–1000 AU. These observations, which were obtained …

We use a homogeneous catalogue of 42 000 main-sequence wide binaries identified by
Gaia to measure the mass ratio distribution, p (q), of binaries with primary masses 0.1< M …

We present mid-infrared spectra of T Tauri stars in the Taurus star-forming region obtained
with the Spitzer Infrared Spectrograph (IRS). For the first time, the 5-36 μm spectra of a large …
