  • Distribution of Serpens South protostars

    Clusters are common sites of star formation, whose members display varying degrees of mass segregation. The cause may be primordial or dynamical, or a combination both. If mass...
  • Probing midplane structure with DCO+ in HD169142

    We analyze the radial distribution of DCO^+^ in the protoplanetary disk around HD 169142, a Herbig Ae type star, with the aim of determining possible formation scenarios of...
  • Monoceros R2 filament hub FIR observations

    We present far-infrared observations of Monoceros R2 (a giant molecular cloud at approximately 830pc distance, containing several sites of active star formation), as observed at...
  • H_2_CO production in HD 163296

    We analyze the radial distribution of H_2_CO and C^18^O in the protoplanetary disk around HD 163296, a Herbig Ae type protostar, with the aim of determining possible formation...
  • 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...
  • G35.20-0.74N VLA continuum images

    Atacama Large Millimeter/submillimeter Array (ALMA) observations of the high-mass star-forming region G35.20-0.74N have revealed the presence of a Keplerian disk in core B...
  • SDC335.579-0.292 6, 8, 23 and 25GHz images

    Recent ALMA observations identified one of the most massive star-forming cores yet observed in the Milky Way: SDC335-MM1, within the infrared dark cloud SDC335.579-0.292. Along...
  • Maps and datacubes of NGC 7538 IRS 1

    NGC 7538 IRS 1-3 is a high-mass star-forming cluster with several detected dust cores, infrared sources, (ultra)compact HII regions, molecular outflows, and masers. In such a...
  • Sub-mm images of SSTB213 J041757.75+274105.5

    We observed the proto brown dwarf candidate SSTB213 J041757 with the Submillimeter Array to search for CO molecular outflow emission from the source. Our CO maps do not show any...
  • Herschel EPoS: high-mass overview

    Stars are born deeply embedded in molecular clouds. In the earliest embedded phases, protostars emit the bulk of their radiation in the far-infrared wavelength range, where...
  • IRAS 16293-2422 ALMA maps

    We focus on the kinematical properties of a proto-binary to study the infall and rotation of gas toward its two protostellar components. We present ALMA Science Verification...
  • Chamaeleon III 870um sources maps

    The nearby Chamaeleon molecular cloud complex is a good laboratory for studying the process of low-mass star formation because it consists of three clouds with very different...
  • Missing low-mass stars in S254-S258

    The aim of this study was to find an explanation for the remarkable morphology of the central part of the S254-S258 star forming complex. We performed a deep Chandra X-ray...
  • Youngest massive protostars in the LMC

    We demonstrate the unique capabilities of Herschel to study very young luminous extragalactic young stellar objects (YSOs) by analyzing a central strip of the Large Magellanic...
  • CO and HC3N maps of IRAS 20050+2720

    This is the third in a series of papers devoted to studying intermediate- mass molecular outflows and their powering sources in detail and with high -angular resolution. This...
  • Abundances of HDE 341617

    Detailed atmospheric abundances have been calculated for a sample of A-G supergiant stars with IR fluxes and/or high galactic latitudes. HD 172481 and HD 158616 show clear...
  • Protostellar cores

    Basing on the coagulation model of Ossenkopf (1993A&A...280..617O), we systematically computed and tabulated the opacity of dust in dense protostellar cores between 1...
  • AKARI Far-Infrared Surveyor YSO catalog

    We demonstrate the use of the AKARI all-sky survey photometric data in the study of galactic star formation. Our aim was to select young stellar objects (YSOs) in the AKARI...
