Context. The ESO public survey VISTA Variables in the Vía Láctea (VVV) surveyed the inner
Galactic bulge and the adjacent southern Galactic disk from 2009–2015. Upon its …

Context. Star-forming regions, stellar associations, and open clusters are fundamental stellar
systems where predictions from star-formation theories can be robustly contrasted with …

Early expansion plays a fundamental role in the dynamical evolution of young star clusters.
However, until very recently most of our understanding of cluster expansion was based only …

Sun-like stars are thought to accrete most of their final mass during the protostellar phase,
during which the stellar embryo is surrounded by an infalling dense envelope. We present …

The VISIONS public survey provides large-scale, multi-epoch imaging of five nearby star-
forming regions at sub-arcsecond resolution in the near-infrared. All data collected within the …

during which the stellar embryo is surrounded by an infalling dense envelope. We present …

It has been long understood that star and planet formation starts from the collapse of dense
cores of material embedded in the more diffuse interstellar medium. As these collapse under …

(blue channel), H (green channel), and KS (red channel). The top left panel displays the …
