Stellar distances constitute a foundational pillar of astrophysics. The publication of 1.47
billion stellar parallaxes from Gaia is a major contribution to this. Despite Gaia's precision …

The unprecedented quality of the astrometric measurements obtained with the ESA Gaia
spacecraft have initiated a revolution in Milky Way astronomy. Studies of star clusters in …

The nature and origin of free-floating planets (FFPs) are still largely unconstrained because
of a lack of large homogeneous samples to enable a statistical analysis of their properties …

We present the first results of the eXtreme UV Environments (XUE) James Webb Space
Telescope (JWST) program, which focuses on the characterization of planet-forming disks in …

Context. Stellar ages are key to improving our understanding of different astrophysical
phenomena. However, many techniques to estimate stellar ages are highly model …

The accuracy of stellar distances inferred purely from parallaxes degrades rapidly with
distance. Proper motion measurements, when combined with some idea of typical velocities …

While intensively studied, it remains unclear how the star formation (SF) in infrared dark
clouds (IRDCs) compares to that of nearby clouds. We study G351. 77-0.53 (henceforth …

Context. Chamaeleon is the southernmost low-mass star-forming complex within 200 pc
from the Sun. Its stellar population has been extensively studied in the past, but the current …

Physical Properties of 5000 Cool Large Magellanic Cloud Supergiants with Gaia XP Spectra:
A Detailed Portrait of the Upper HR Diagram Hints at Missing Supernova Progenitors …

Context. The Carina Nebula complex (CNC) is one of the most massive and active star-
forming regions in our Galaxy and it contains several large young star clusters. The …
