  • Gal. midplane Spitzer/IRAC candidate YSOs (SPICY)

    We present ~120000 Spitzer/IRAC candidate young stellar objects (YSOs) based on surveys of the Galactic midplane between l~255{deg} and 110{deg}, including the GLIMPSE I, II,...
  • Nobeyama mapping survey of SCUBA-2 cores

    We present the results of on-the-fly mapping observations of 44 fields containing 107 SCUBA-2 cores in the emission lines of molecules N_2_H^+^, HC_3_N, and CCS at 82-94GHz...
  • MAPS III. Radial chemical substructures toward 5 stars

    The Molecules with ALMA at Planet-forming Scales (MAPS) Large Program provides a detailed, high-resolution (~10-20au) view of molecular line emission in five protoplanetary...
  • Gaia stellar flyby analysis for spiral arm hosts

    Scattered-light imaging studies have detected nearly two dozen spiral arm systems in circumstellar disks, yet the formation mechanisms for most of them are still under debate....
  • Multiple maser transitions from G358.93-0.03 burst

    The high-mass young stellar object G358.93-0.03 underwent an accretion burst during the period from 2019 January to June. Given its extraordinary conditions, a number of new...
  • C^18^O dense cores in Orion A molecular cloud

    The mass distribution of dense cores is a potential key to understanding the process of star formation. Applying dendrogram analysis to the CARMA-NRO Orion C^18^O (J=1-0) data,...
  • WISE Green Objects massive YSOs in the Gal. plane

    Massive young stellar objects (MYSOs) play a crucial role in star formation. Given that MYSOs were previously identified based on the extended structure and the observational...
  • NEOWISE variability of Gaia Herbig Ae/Be & Be stars

    Light variability is an essential attribute of young stellar objects (YSOs) at the pre-main-sequence (PMS) stage, which can be treated as an indicator to trace star formation....
  • Statistical study of NEOWISE 6.7GHz methanol masers

    We present a statistical study of infrared variability using the Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) database for a sample consisting of 1085...
  • Opt. spectra of blue MIR objects in LMC

    We present low-resolution optical spectra and classifications of 92 blue objects with mid-infrared excesses in the Large Magellanic Cloud. The majority of these objects were...
  • Extension of HOPS out to 500pc (eHOPS). I. Aquila

    We present a Spitzer/Herschel focused survey of the Aquila molecular clouds (d~436pc) as part of the eHOPS (extension of the Herschel orion protostar survey, or HOPS, Out to 500...
  • YSO candidates from LAMOST LRS DR9 & ZTF

    As astronomical data sets become too large for traditional analysis approaches, more machine-learning algorithms are employed in astronomy. A wealth of light variation data have...
  • NEOWISE variability analysis of ATLASGAL sources

    This study focuses on the analysis of mid-infrared variability in a sample of high-mass young stellar objects (YSOs) associated with the cataloged sources from the APEX...
  • T-ReX: the Tarantula-Revealed by X-rays

    The Tarantula Nebula (30 Doradus, 30 Dor) is the most important star-forming complex in the Local Group, offering a microscope on starburst astrophysics. At its heart lies the...
  • YSOs from LAMOST DR9 using deep learning

    Young stellar objects (YSOs) represent the earliest stage in the process of star formation, offering insights that contribute to the development of models elucidating star...
  • YSOs in Camelopardalis

    Using photometric data of infrared surveys, young stellar object (YSO) status is verified for 141 objects selected in our previous papers in the Cassiopeia and Camelopardalis...
  • Kinematic distance ambiguity

    We investigate the use of HI data to resolve the near/far ambiguity in kinematic distances of massive young stellar object (MYSO) candidates. Kinematic distances were obtained...
  • Young stellar outflows near-IR imaging

    We have carried out a near-infrared imaging survey of luminous young stellar outflow candidates using the United Kingdom Infrared Telescope. Observations were obtained in the...
  • Red MSX survey (RMS) massive young stars

    The Red MSX Source (RMS) survey has identified a large sample of massive young stellar objects and ultra compact HII regions from a sample of ~2000 MSX and Two Micron All Sky...
  • AMI 1.8cm observations in c2d small clouds

    We perform deep 1.8-cm radio continuum imaging towards 13 protostellar regions selected from the Spitzer c2d small clouds and cores programme at high resolution (25-arcsec) in...
