Due to the recent dramatic technological advances, infrared interferometry can now be applied to new classes of objects, resulting in exciting new science prospects, for instance, in the area of high-mass star formation. Although extensively studied at various wavelengths, the process through which massive stars form is still only poorly understood. For instance, it has been proposed that massive stars might form like low-mass stars by mass accretion through a circumstellar disk/envelope, or… Expand


Mid-infrared interferometry of massive young stellar objects. I. VLTI and Subaru observations of the
Context. Our knowledge of the inner structure of embedded massive young stellar objects is still quite limited. Thus, it is difficult to decide to what extent the mass accumulation onto formingExpand
The origin of mid-infrared emission in massive young stellar objects: multi-baseline VLTI observations of W33A
Aims. In this paper we aim to determine the structure on 100 AU scales of the massive young stellar object W33A, using interferometric observations in the mid-infrared. This emission could be causedExpand
A hot compact dust disk around a massive young stellar object
Near-infrared interferometric observations that spatially resolve the astronomical-unit-scale distribution of hot material around a high-mass (∼20 solar masses) young stellar object show an elongated structure with a size of ∼13 × 19 astronomical units, consistent with a disk seen at an inclination angle of ∼45°.

Visual/infrared interferometry of Orion Trapezium stars: preliminary dynamical orbit and aperture synthesis imaging of the θ1 Orionis C system
Context. Located in the Orion Trapezium cluster, θ^1 Ori C is one of the youngest and nearest high-mass stars (O5-O7) known. Besides its unique properties as a magnetic rotator, the system is alsoExpand
First L-Band Interferometric Observations of a Young Stellar Object: Probing the Circumstellar Environment of MWC 419
We present spatially resolved K- and L-band spectra (at spectral resolution R = 230 and R = 60, respectively) of MWC 419, a Herbig Ae/Be star. The data were obtained simultaneously with a newExpand
Outflows from Massive Young Stellar Objects as Seen with the Infrared Array Camera
The bipolar outflow from the massive star-forming cluster in DR 21 is one of the most powerful known, and in IRAC images the outflow stands out by virtue of its brightness at 4.5 ?m (band 2). Indeed,Expand
Infall of gas as the formation mechanism of stars up to 20 times more massive than the Sun
Observations of an ammonia line towards a high-mass star forming region conclude that the gas is falling inwards towards a very young star of ∼20M[circdot], in line with theoretical predictions of non-spherical accretion. Expand
AMBER, the near-infrared spectro-interferometric three-telescope VLTI instrument
Context: Optical long-baseline interferometry is moving a crucial step forward with the advent of general-user scientific instruments that equip large aperture and hectometric baseline facilities,Expand
Massive star formation in 100,000 years from turbulent and pressurized molecular clouds
It is shown that t*f is determined by the conditions in the star's natal cloud, and is typically ∼105 yr, which is sufficient to overcome radiation pressure from ∼100M[circdot] protostars, while simultaneously driving intense bipolar gas outflows. Expand
Tracing the young massive high-eccentricity binary system Theta 1 Orionis C through periastron passage
Context. The nearby high-mass star binary system θ 1 Ori C is the brightest and most massive of the Trapezium OB stars at the core of the Orion Nebula Cluster, and it represents a perfect laboratoryExpand
