  • Classifier catalogue of class II YSO posteriors

    A naive Bayes classifier for identifying Class II YSOs has been constructed and applied to a region of the Northern Galactic Plane containing 8 million sources with good quality...
  • Catalog of Star-Forming Regions in the Galaxy

    This Catalog of Star-Forming Regions in the Galaxy contains coordinates and fluxes of young objects in the radio and infrared, as well as data on the radial velocities of...
  • Galactic kinematics from YSOs sample

    Based on published sources, we have created a kinematic database on 220 massive (>10M_{sun}) young Galactic star systems located within <3 kpcof the Sun. Out of them,...
  • Gas Survey of Protoplanetary Systems. I.

    We describe a large-scale far-infrared line and continuum survey of protoplanetary disk through to young debris disk systems carried out using the ACS instrument on the Herschel...
  • Near-infrared survey of bright rimmed clouds

    We conducted wide-field near-infrared imaging observations of 32 bright rimmed clouds (BRCs). Given a detection limit of 17.7mag at the K-band, we identified 2099 objects as...
  • Faint companions around YSOs in TMC

    We have conducted near-infrared spectroscopy of 26 faint objects around young stellar objects in the Taurus molecular cloud. These objects were detected during a course of...
  • Chandra X-ray flares in rho Ophiuchi

    We report on the results of a systematic study of X-ray flares from low-mass young stellar objects, using two deep exposure Chandra observations of the main region of the {rho}...
  • YSOs in Perseus Molecular Cloud

    We present an analysis of 288 young stellar objects (YSOs) in the Perseus molecular cloud that have well defined g and r-band lightcurves from the Zwicky Transient Facility. Of...
  • M120.1+3.0 molecular cloud CO observations

    We present large-scale (2{deg}x2{deg}) observations toward the molecular cloud M120.1+3.0, using ^12^CO, ^13^CO and C^18^O (J=1-0) data from the Purple Mountain Observatory...
  • Long-Term Multicolour Photometry of YSOs

    Results from long-term multicolour optical photometric observations of the pre-main sequence stars FHO 26, FHO 27, FHO 28, FHO 29, and V1929 Cyg collected during the period from...
  • JWST observations of M33

    Young stellar objects (YSOs) are the gold standard for tracing star formation in galaxies but have been unobservable beyond the Milky Way and Magellanic Clouds. But that all...
  • ALMA 3-mm sources in the Orion-KL region

    High-energy processes are ubiquitous even in the earliest stages of protostellar evolution. Motivated by the results of our systematic search for intense centimetre radio flares...
  • M33 massive young stellar objects

    We present a supervised machine learning classification of stellar populations in the Local Group spiral galaxy M 33. The Probabilistic Random Forest (PRF) methodology,...
  • CQ Tau images in near-infrared

    We present new high-contrast images in near-infrared wavelengths ({lambda}c = 1.04, 1.24, 1.62, 2.18, and 3.78 um) of the young variable star CQ Tau, aiming to constrain the...
  • Polarimetric study of LDN 1616 background stars

    The Lynds' Dark Nebula (LDN) 1615/1616 and CB 28 (hereafter L1616) together form a cometary globule located at an angular distance of about 8{deg} west of the Orion OB1...
  • NGC 6822 massive young stellar objects

    We present a supervised machine learning methodology to classify stellar populations in the Local Group dwarf-irregular galaxy NGC 6822. Near-IR colours (J-H, H-K, and J-K),...
  • Chemical abundances of the Orion Complex

    Due to its proximity, the Orion star forming region is often used as a proxy to study processes related to star formation and to observe young stars in the environment they were...
  • VLA compact radio sources in the ONC

    We present a newly enlarged census of the compact radio population towards the Orion Nebula Cluster (ONC) using high-sensitivity continuum maps (3-10uJy/beam) from a total of...
  • XGBoost ML classifier of BASS DR3 sources

    The Beijing-Arizona Sky Survey (BASS) Data Release 3 (DR3) catalogue was released in 2019, which contains the data from all BASS and the Mosaic z-band Legacy Survey (MzLS)...
  • The Gaia view of the Cepheus flare

    We present a new census of candidate pre-main-sequence stars in the Cepheus flare star-forming region, based on Gaia EDR3 parallaxes, proper motions, and colour-magnitude...
