The discovery of large numbers of young low-mass stars and brown dwarfs over the past
decade has made it possible to investigate star formation and early evolution in a previously …

Determining the sequence of events in the formation of stars and planetary systems and
their timescales is essential for understanding those processes, yet establishing ages is …

We present results of a spectroscopic survey for new K-and M-type members of Scorpius–
Centaurus (Sco–Cen), the nearest OB Association (∼ 100–200 pc). Using an X-ray, proper …

Abstract The Taurus-Auriga complex is the prototypical low-mass star-forming region, and
provides a unique testbed of the star formation process, which left observable imprints on …

Transitional disks are objects whose inner disk regions have undergone substantial
clearing. The Spitzer Space Telescope produced detailed spectral energy distributions …

We present a detailed study of the evolution of giant molecular clouds (GMCs) in a galactic
disc simulation. We follow individual GMCs (defined in our simulations by a total column …

Giant molecular clouds (GMCs) are the primary reservoirs of cold, star-forming molecular
gas in the Milky Way and similar galaxies, and thus any understanding of star formation must …

The idea that non-steady accretion during the embedded phase of protostar evolution can
produce the observed luminosity spread in the Herzsprung–Russell diagram (HRD) of …

We present a study of the three dimensional structure, kinematics, and age distribution of the
Orion OB association, based on the second data release of the Gaia satellite (Gaia DR2) …

We have compiled a significantly updated and comprehensive census of massive stars in
the nearby Cygnus OB2 association by gathering and homogenizing data from across the …
