Stellar population in Chamaeleon I
I present a new census of the stellar population in the ChamaeleonI star-forming region. Using optical and near-IR photometry and follow-up spectroscopy, I have discovered 50... -
A database of dense cores mapped in ammonia
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... -
Cepheus flare molecular clouds
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... -
Spectra of brown dwarf candidates in ONC from JWST
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... -
Membership analysis of the region around Tr37 with Gaia
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... -
The Oceanus moving group members from Gaia DR3
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... -
Tuc-Hor members with TESS LCs & Gaia data
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... -
ACA 870um continuum survey of 300 HOPS sources
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... -
The IGRINS YSO survey. III. Oph & Upper Sco
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... -
Brackett emission lines in young star APOGEE sp.
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... -
SPYGLASS. II. Cepheus Far North candidate members
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... -
Stellar contents in the Sh2-112 cloud complex
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... -
CO molecular clumps and YSOs in NGC 602 region
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... -
ALMA 12CO obs. of YSOs in the Serpens region
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... -
VLT-KMOS NIR sp. of SSTc2d J163134.1-240060
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... -
MWISP CO obs. toward a 153.60<l<156.50{deg} Gal. reg.
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... -
Chandra obs. of the Trifid region & ARCoIRIS sp.
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... -
Photometric light curve of V1515 Cyg
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... -
Young stellar objects Gaia EDR3 properties
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... -
LDT UBVRI photometry of 14 T-Tauri
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...
