We present a database of 264 cores mapped in the (J,K)=(1,1) and (2,2) lines of NH_3_. We list the core gas properties-peak positions, total ammonia column densities, intrinsic...

Results of an objective prism Schmidt survey are combined with IRAS survey data in order to assess the star-forming activity in the Cepheus Flare, a nearby giant molecular cloud...

We have used the multiobject mode of the Near-Infrared Spectrograph (NIRSpec) on board the James Webb Space Telescope (JWST) to obtain low-resolution 1-5um spectra of 22 brown...

Identifying and characterizing young populations of star-forming regions are crucial to unraveling their properties. In this regard, Gaia-DR3 data and machine-learning tools are...

We report the discovery of the Oceanus moving group, a ~500Myr old group with 50 members and candidate members at distances 2-50pc from the Sun, using an unsupervised clustering...

The Tucana-Horologium association (Tuc-Hor) is a 40Myr old moving group in the southern sky. In this work, we measure the rotation periods of 313 Tuc-Hor objects with TESS light...

We present an 870{mu}m continuum survey of 300 protostars from the Herschel Orion Protostar Survey using the Atacama Compact Array (ACA). These data measure protostellar flux...

We used the Immersion GRating Infrared Spectrometer (IGRINS) to determine fundamental parameters for 61 K- and M-type young stellar objects (YSOs) located in the Ophiuchus and...

Very young (t<~10Myr) stars possess strong magnetic fields that channel ionized gas from the interiors of their circumstellar disks to the surface of the star. Upon impacting...

Young stellar populations provide a record of past star formation, and by establishing their members' dynamics and ages, it is possible to reconstruct the full history of star...

We present the star formation activity around the emission nebula Sh2-112. At a distance of ~2.1kpc, this HII complex, itself 3pc in radius, is illuminated by the massive star...

NGC 602 is a young, low-metallicity star cluster in the "Wing" of the Small Magellanic Cloud. We reveal the recent evolutionary past of the cluster through analysis of...

We present the results from an Atacama Large Millimeter/submillimeter Array (ALMA) 1.3mm continuum and ^12^CO (J=2-1) line survey spread over 10deg^2^ in the Serpens...

We report the serendipitous discovery of an elliptical shell of CO associated with the faint stellar object SSTc2d J163134.1-240060 as part of the "Ophiuchus Disk Survey...

We present observations of the J=1-0 transition lines of ^12^CO, ^13^CO, and C^18^O toward the Galactic region of 153.60{deg}<=l<=156.50{deg} and...

The dynamical states of molecular clouds may affect the properties of the stars they form. In the vicinity of the Trifid Nebula (d=1180+/-25pc), the main star cluster (Trifid...

Historically, FU Orionis-type stars are low-mass, pre-main-sequence stars. The members of this class experience powerful accretion outbursts and remain in an enhanced accretion...

Identifying the young optically visible population in a star-forming region is essential for fully understanding the star formation event. In this paper, we identify 211...

Interpreting the short-timescale variability of the accreting, young, low-mass stars known as Classical T-Tauri stars remains an open task. Month-long, continuous light curves...

We have performed a high-resolution 4-13{mu}m spectral survey of the hot molecular gas associated with the massive protostars AFGL-2591 and AFGL-2136. Here we present the...
