  • X-Shooter spectroscopy of YSOs in Lupus

    A homogeneous determination of basic stellar parameters of young stellar object (YSO) candidates is needed to confirm their pre-main sequence evolutionary stage, membership to...
  • Multiwavelength fluxes of RCW120

    The expansion of HII regions can trigger the formation of stars. An overdensity of young stellar objects (YSOs) is observed at the edges of HII regions but the mechanisms that...
  • Lupus YSOs X-shooter spectroscopy

    The mass accretion rate, M_acc_, is a key quantity for the understanding of the physical processes governing the evolution of accretion discs around young low-mass...
  • YSO candidates in IRAS 20319+3958

    Globules and pillars, impressively revealed by the Spitzer and Herschel satellites, for example, are pervasive features found in regions of massive star formation. Studying...
  • Accretion-rotation connection in NGC 2264

    The low spin rates measured for solar-type stars at an age of a few Myr (~10% of the break-up velocity) indicate that some mechanism of angular momentum regulation must be at...
  • A grid of 1D low-mass star formation models

    Numerical simulations of star formation are becoming ever more sophisticated, incorporating new physical processes in increasingly realistic set-ups. These models are being...
  • OMC-2 FIR 3 and FIR 4 [OI] maps

    We present the first detection of a jet in the far-IR [OI] lines from an intermediate mass protostar. We have carried out a Herschel/PACS spectral mapping study in the [OI]...
  • Far-IR lines in YSOs Herschel-PACS

    Gas plays a major role in the dynamical evolution of young stellar objects (YSOs). Its interaction with the dust is the key to our understanding planet formation later on in the...
  • IRAS08589-4714 molecular gas

    We present an analysis of the region IRAS 08589-4714 with the aim of characterizing the molecular environment. We observed the ^12^CO(3-2), ^13^CO(3-2), C^18^O(3-2),...
  • NH and AV Towards YSOs in the ONC

    We characterise the relation between the gas and dust content of the interstellar medium towards young stellar objects in the Orion Nebula Cluster. X-ray observations provide...
  • Spectral cube toward NGC 6334 I and I(N)

    The HF molecule has been proposed as a sensitive tracer of diffuse interstellar gas, while at higher densities its abundance could be influenced heavily by freeze-out onto dust...
  • HD 100546 and TW Hya model abundances

    The composition of planetary solids and gases is largely rooted in the processing of volatile elements in protoplanetary disks. To shed light on the key processes, we carry out...
  • Transition disk survey

    Understanding disk evolution and dissipation is essential for studies of planet formation. Transition disks, i.e., disks with large dust cavities and gaps, are promising...
  • HD61005 SPHERE H and Ks images

    Debris disks offer valuable insights into the latest stages of circumstellar disk evolution, and can possibly help us to trace the outcomes of planetary formation processes. In...
  • Vilnius photometry near Sh 2-205

    We present the results of CCD photometry in the seven-color Vilnius system for 302 stars in the 12x12 arcmin area in the vicinity of the dark cloud TGU H942 P7. Observational...
  • Giant molecular filaments in the Milky Way

    Filamentary structures are common morphological features of the cold, molecular interstellar medium (ISM). Recent studies have discovered massive, hundred-parsec-scale filaments...
  • Water lines spectra of 4 protostellar objects

    We present Herschel/HIFI observations of 14 water lines in a small sample of galactic massive protostellar objects: NGC6334I(N), DR21(OH), IRAS16272-4837, and IRAS05358+3543....
  • Perseus dust optical depth and column density maps

    We present optical depth and temperature maps of the Perseus molecular cloud, obtained combining dust emission data from the Herschel and Planck satellites and 2MASS/NIR dust...
  • VCNS II. The IR-excess-selected population

    We performed a deep wide-field (6.76 square-degrees) near-infrared survey with the VISTA telescope that covers the entire extent of the Carina nebula complex. Complementing the...
  • Catalog of dense cores in Aquila from Herschel

    We present and discuss the results of the Herschel Gould Belt survey (HGBS) observations in an ~11deg^2^ area of the Aquila molecular cloud complex at d~260pc, imaged with the...
