We present a technique-led review of the progression of precise radio astrometry, from the
first demonstrations, half a century ago, until to date and into the future. We cover the …

We present an overview of the Large Program," Early Planet Formation in Embedded Disks
(eDisk)," conducted with the Atacama Large Millimeter/submillimeter Array (ALMA). The …

High dust density in the midplane of protoplanetary disks is favorable for efficient grain
growth and can allow fast formation of planetesimals and planets, before disks dissipate …

Aims. We aim to study vertical settling and radial drift of dust in protoplanetary disks from a
different perspective: an edge-on view. An estimation of the amplitude of settling and drift is …

We present a uniform catalog of accurate distances to local molecular clouds informed by
the Gaia DR2 data release. Our methodology builds on that of Schlafly et al. First, we infer …

Annular structures (rings and gaps) in disks around pre-main-sequence stars have been
detected in abundance towards class II protostellar objects that are approximately 1,000,000 …

We address the problem of the origin of massive stars, namely the origin, path, and
timescale of the mass flows that create them. Based on extensive numerical simulations, we …

Context. Complex organic molecules (COMs) have been detected in a few Class 0
protostars but their origin is not well understood. While the usual picture of a hot corino …

Observations indicate that molecular clouds are strongly magnetized, and that magnetic
fields influence the formation of stars. A key observation supporting the conclusion that …

The orientation between a star's spin axis and a planet's orbital plane provides valuable
information about the system's formation and dynamical history. For non-transiting planets at …
