  • Multiwavelength photometry of Sh 2-138 YSOs

    We present a multiwavelength study of the Sh 2-138, a Galactic compact HII region. The data comprise of optical and near-infrared (NIR) photometric and spectroscopic...
  • SVM selection of WISE YSO Candidates

    We explored the AllWISE catalogue of the Wide-field Infrared Survey Explorer mission and identified Young Stellar Object candidates. Reliable 2MASS and WISE photometric data...
  • JCMT Gould Belt Survey: W40 complex

    We present SCUBA-2 450{mu}m and 850{mu}m observations of the W40 complex in the Serpens-Aquila region as part of the James Clerk Maxwell Telescope (JCMT) Gould Belt Survey (GBS)...
  • MHO catalogue for Cassiopeia and Auriga

    We present the analysis of 35.5deg^2^ of images in the 1-0 S(1) line of H_2_ from the UK Widefield Infrared Survey for H_2_ (UWISH2) towards Cassiopeia and Auriga. We have...
  • Eruptive variable protostars from VVV EW

    In a companion work (Contreras Pena et al., 2017MNRAS.465.3011C, Paper I), we detected a large population of highly variable Young Stellar Objects (YSOs) in the Vista Variables...
  • NGC 7538 region YSOs

    Deep optical photometric data on the NGC 7538 region were collected and combined with archival data sets from the Chandra, 2MASS and Spitzer surveys to generate a new catalogue...
  • SAGE LMC point-sources classification

    The Infrared Spectrograph (IRS) on the Spitzer Space Telescope observed nearly 800 point sources in the Large Magellanic Cloud (LMC), taking over 1000 spectra. 197 of these...
  • Catalogue of eruptive YSOs and unusual stars

    We present a catalogue of 618 high-amplitude infrared variable stars (1<{Delta}K<5mag) detected by the two widely separated epochs of 2.2{mu}m data in the UKIDSS Galactic...
  • Young stellar objects in W49A and W51

    We have compared the star-formation properties of the W49A and W51 regions by using far-infrared data from the Herschel infrared Galactic Plane Survey (Hi-GAL) and 850-um...
  • The SCOPE 850um compact source catalogue

    We present the first release of the data and compact-source catalogue for the JCMT Large Program SCUBA-2 Continuum Observations of Pre-protostellar Evolution (SCOPE). SCOPE...
  • 139 high-amplitude variable stars

    We have determined the rate of large accretion events in Class I and II young stellar objects (YSOs) by comparing the all-sky digitized photographic plate surveys provided by...
  • New 1.1mm data of IC 348 circumstellar discs

    We present the most complete sample of mm measurements of protoplanetary discs in the star-forming region IC 348 to date. New observations from the Large Millimetre Telescope...
  • Infall and outflow on massive star-forming regions

    A total of 188 high-mass outflows have been identified from a sample of 694 clumps from the Millimetre Astronomy Legacy Team 90GHz survey, representing a detection rate of...
  • Runaway gas accretion and ALMA observations

    Due to recent high-resolution ALMA observations, there is an accumulating evidence for presence of giant planets with masses from ~0.01M_J_ to a few M_J_ with separations up to...
  • Young stellar population of metal-poor NGC 6822

    We present a comprehensive study of massive young stellar objects (YSOs) in the metal-poor galaxy NGC 6822 using IRAC and MIPS data obtained from the Spitzer Space Telescope. We...
  • Large-scale star formation in Auriga region

    New observations in the VI bands along with archival data from the 2MASS and WISE surveys have been used to generate a catalogue of young stellar objects (YSOs) covering an area...
  • Variable stars in the Sh 2-170 H II region

    We present multi-epoch deep (~20mag) Ic-band photometric monitoring of the Sh 2-170 star-forming region to understand the variability properties of pre-main-sequence (PMS)...
  • Crystalline silicate absorption at 11.1{mu}m

    Utilizing several instruments on 4-8m telescopes, we have observed a large sample of objects in the mid-infrared (8-13{mu}m). These comprise a few evolved stars, multiple...
  • IR and sub-mm variability in protostars

    We study the relationship between the mid-infrared (mid-IR) and sub-millimetre (sub-mm) variability of deeply embedded protostars using the multi-epoch data from the Wide-field...
  • The ASAS-SN catalogue of variable stars - VIII

    Some young stellar objects such as T Tauri-like 'dipper' stars vary due to transient partial occultation by circumstellar dust, and observations of this phenomenon inform us of...
