  • Low-mass population in {rho} Oph cloud

    Star formation theories are currently divergent regarding the fundamental physical processes that dominate the substellar regime. Observations of nearby young open clusters...
  • 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...
  • YSOs in DROXO (Deep rho Oph XMM obs.)

    X-rays from very young stars are powerful probes to investigate the mechanisms at work in the very first stages of the star formation and the origin of X-ray emission in very...
  • Red MSX Survey (RMS): bolometric fluxes of YSOs

    The Red MSX Source (RMS) survey is returning a large sample of massive young stellar objects (MYSOs) and ultra-compact (UC) HII regions using follow-up observations of...
  • Fermi sources with massive YSO associations

    Massive protostars have associated bipolar outflows that can produce strong shocks when they interact with the surrounding medium. At these shocks, particles can be accelerated...
  • 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...
  • 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...
  • X-ray view of IC348

    IC348 is a nearby (~310pc), young (~2-3Myr) open cluster with >300 members identified from optical and infrared observations. We study the properties of the coronae of the...
  • YSOs in 9 LMC star forming regions

    We introduce a new set of selection criteria for the identification of infrared bright young stellar object (YSO) candidates and apply them to nine HII regions in the Large...
  • 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...
  • X-shooter spectra of 12 young stellar objects

    We present high-quality, medium-resolution X-shooter/VLT spectra in the range 300-2500nm for a sample of 12 very low mass stars in the {sigma} Orionis cluster. The sample...
  • YSOs in Herschel-Hi-GAL survey

    The Herschel survey of the Galactic plane (Hi-GAL) provides a unique opportunity to study star formation over large areas of the sky and different environments in the Milky Way....
  • AFGL 2591 multi-wavelength maps

    While it is currently unclear from a theoretical standpoint which forces and processes dominate the formation of high-mass stars, and hence determine the mode in which they...
  • SINFONI K-band observations of IRS54(YLW52)

    Molecular outflows from very low-mass stars (VLMSs) and brown dwarfs have been studied very little. So far, only a few CO outflows have been observed, allowing us to map the...
  • Near-infrared variability in RCW 38

    We want to study the content of young stellar objects in the RCW 38 cluster by means of multi-epoch variability studies. We performed a three-month near-infrared (NIR)...
  • L1448 and HH211 CO(6-5) velocity maps

    Observations of CO rotational transitions in the 0.3-0.4 millimeter range, now possible from exceptional sites on the ground, provide the opportunity of studing the warm...
  • Transitions in OMC-2 FIR 4 in the far-IR

    Broadband spectral surveys of protostars offer a rich view of the physical, chemical and dynamical structure and evolution of star-forming regions. The Herschel Space...
  • Young stellar clusters in the Rosette

    The Rosette complex is a well studied region of the galactic plane which presents the apparent characteristics of a triggered star forming region. This is however still debated...
  • The VLTI/MIDI survey of Massive YSOs

    Due to inherent difficulties involved in observations and theoretical/numerical simulations of the formation of massive stars, an understanding of the early evolutionary phases...
  • NGC 1333-IRAS 4A C^18^O, NO and O_2_ spectra

    According to traditional gas-phase chemical models, O_2_ should be abundant in molecular clouds, but until recently, attempts to detect interstellar O_2_ line emission with...
